I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Need to select new mobo - and power?

A motherboard doesn't come with a processor. If you want an AMD processor search for an AMD motherboard. Socket AM2 or AM2+ 64 bit processors and a motherboard that supports AM2 or AM2+ CPU's are good. Just choose a board and processor that suits your budget. If you are in the US you can start looking here http://www.newegg.com and look at the motherboard specs for the type of memory it takes. DDR2 memory may be what you need to get. Everything else may work... A SATA hard drive may be needed too for this upgrade. A good 450 watt power supply should work fine

I would like to replace one of my system MOBO, and need help selecting a good one. I want to replace one of my ASUS A7V8X boards with something that will run the latest AMD CPU's but need at least 4 or more PCI slots (2 for SCSI cards; 1 for Promise card; 1 for USB card). I can live without an AGP slot if onboard video is good. Would need onboard sound, NIC, and have never used Sata drives (prefer scsi 320). Any help would be great!

Thanks in advance.

Hi everyone! Recently did a reinstall of windows (yikes, what a pain), recently did all critical updates and installed SP2.

Now, when I attempt to shut down and select "Turn off Computer" from the start menu it no longer powers down completely, it gives me the "It is Now Safe To Turn of Your Computer" screen,,,,ugh!!

I've not messed with my bios....APM is enabled.

I've gone into Power Options and selected to not enable hibernation and I've selected Always On power schemes with all options to never.

By the way, before the install of SP2 it would shut down normally, please help so I don't have to use the power button!!

Thanks!!

Hello I Reboot boot and change device proper select power after recently heve moved to the UK from the US My PC was running on Reboot and select proper boot device after power change power converters to start until I could replace the power supply with a UK version My first problem is that I burned up the power converter I was using I ordered a replacement that would work with UK power I replaced the power supply and have double checked all connections and started up my PC to get the error message quot reboot and select proper boot device quot I have tried checking the boot order in the bios and it is prioritizing my hard drive st I have tried disabling the cd dvd drive as well I have tried removing the motherboard battery and reinstalling it and trying but besides telling me it needs a set up the results are the same I'm now in a pickle here as I am using a tablet to request help I have no boot disc or method of burning one and I need to save recover the software on the hard drive at the least though I really do prefer to make it all work like it was None of my back ups will arrive for a few weeks Any advice My PC stats are on my user info Thank you

A:Reboot and select proper boot device after power change

At this point i would suggest double checking all the cable(s) going from the hard drive to the motherboard to see if something possibly came loose during shipping(even if it was packed well it still could happen). If that does not do anything; then its quite possible since you moved here to the u.s. from overseas that you need u.s. power supply as the electric grids in the u.s. are much different than overseas due to the voltage they operate on.

Ok so i do know what the no Power and supply 100%, mobo are power problem is this is more about what i can do to use my computer until i can fix the problem Ill start off with what the problem is My computer wont turn on from the get go i knew the power supply was okay Power supply and mobo are 100%, no power because the mother board has a green light on it showing that its getting power of course just in case i tried putting a new supply in but there were no changes At first glance the mother board looked good No blown resistors or anything of that sort i sent it to a friend to check it out though once again just to be thorough and sure Finally after Power supply and mobo are 100%, no power hours of tedious searching i found the problem The chip that the power button plugs into has blown out Very happy thats all it is Now my question to all of you is is there anyway to bypass using that board so i can run my computer until i replace it if i just unplug the little board that the button is a part of the computer obviously does not turn on when i attach the computer to power and i dont know how i can trick it into turning on without having the use of the power button Any info would be greatly appreciated Thanks Ryan nbsp

A:Power supply and mobo are 100%, no power

There are some motherboards that have a power on button directly on the motherboard. I don't suppose you have one of those? There are some BIOS' that can enable the keyboard to power on the PC by pressing any key. I'm using one of them now. Of course, the problem with that is to get the PC started in the first place so you can change the BIOS setting (if it has that setting).

What motherboard do you have?

I just bought an Abit VI7 mobo, and an Antec SP 500W PSU, and put them both into my box. I put in my CPU (an Intel 2600 PIV), my video card (an Envidia Geforce 6200) and one of my HDD's (120 GB WD). I'm not sure how exactly to hook up the power switch, the HDD light, and the reset switch, so I just left those un-connected. When I turned on the power switch in back, I get a small green light on the mobo, and the three lights blink on the keyboard. But my fan to my CPU doesn't spin; nor does my HDD spin up. I'm flummoxed! I can't think of anything that would let power through to the keyboard, yet not power up the HDD. I'm fairly sure all the power cables are connected correctly. Help! What could cause this?

I received a pc to look at with no power, I replaced the psu but still no response at all, disconnected the power switch and shorted across the mobo connections but still no power.
I concluded it must be a problem with the mobo so replaced it and the cpu but still no sign of life from the pc. I then tried the old mobo, psu and memory out of the case but still no signs of life. Tried some other memory but still the same.I shall try the same with the new mobo but am not hopeful.
Have any of you guys any suggestions?

Hi All

I believe my PSU may have blown up (really odd coz wasn't even on at the time!) and damaged my mobo. I have an ASUS K8V SE Deluxe, which has an LED in the bottom corner to indicate power, this no longer comes on. I have swapped PSUs and still nothing.

Does this mean my mobo is dead? If so how likely is it that my CPU has been damaged?

Thanks in advance
 

A:No power to mobo!!??

It actually could be a couple of different things.

How long have you been running your current configuration.

What leads you to believe your PSU blew up. Was there an electrical surge/brownout.

I see the following as possibilities
1. PSU - you said you tried another PSU (known working I hope)
2. Mobo - do you have another mobo you can try
3. CPU - I have seen this before with CPU problems.
4. RAM - not very likely but possible.

Try the following ( remove all unessential devices cdrom/dvdrom/hdd/floppy/sata/pci/
1. Unplug power from pc PSU connected to mobo. Hold in power button for aprox 60 seconds, this will drain any residual power from the mobo capacitors ( caps have a tendancy to work like batteries at times where they can have a "memory" and when power is applied they will not fully operate. ( I wouldn't have believed this myself if I hadn't seen it fix many pc wont power on issues when working HP techs support about 5 years ago)

2. remove cmos battery, or set clear cmos jumper and clear the cmos for a good 30-45 seconds.

3. Reapply power and see what she does.

4. try removing one stick of your RAM if you have 2 sticks, ( again unlikely but possible)

5. is the mobo properly grounded?

Just a quick question for some opinions but I think I know the answer, I had a pc with no power so changed the psu but still no power, checked all connections and tried bypassing the on/off switch but still no power so decided mobo was faulty. I replaced the mobo but still no power, tried another psu and no power, suspect new mobo may be faulty.
I have checked and rechecked all of the connections. the mobo is a socket 478 from Asrock.
Any other suggestions you guys may have would be appreciated.
 

A:New mobo - no power

I think it`s either a dead mobo or possibly a dead cpu.

I suggest you take the cpu to your local pc repair shop and have them test it. It will only cost a few dollars to have this done.

I just bought new mobo, p4 and psu. when i installed everything and tried to boot nothing happened. both the psu fan and the cpu fan started but nothing else. the monitor wouldn't even reconize that the computer was on. Ive double checked all the connections and they are fine.

the only thing that concerns me is the psu connector is 24 pins and the mobo is 20 pin but i was told it would hook up fine just wont use the four extra pins.

I have no idea what to do now any suggestions

is the 4pin atx12v line connected to the motherboard.? you should go over the motherboard's manual for installation and make sure there wasn't a spot you messed up or forgot.

Did you renew the thermal paste between the CPU and the heatsink?

If not, it will overheat and shut down quite quickly to prevent damage.

A:Power Loss -> Bad Mobo / CPU?

Eh fluctuating power is never a good thing, motherboards are very sensitive.

You need to start checking the continuity of your parts. Do you have another PSU you can use temporarily?

Does the green power good LED on the motherboard light up?

A:Can I use this power supply with my mobo?

Okay, so I did a little more research into the "new" power supply (basically looked up what all the Amps and Volts meant). It seems to me from the sticker that there are two +12V rails that are rated as such:

Ultra ULT-V600DR
+12V1: 18A
+12V2: 20A
Max combined wattage: 420W

Across all of the listed voltages, the Max Combined Wattage is 600W. Now I read where the ampere ratings don't directly add up, however there is some formula I found in another thread on overclocking.net that leads me to think that 18+20A would be something above 30A, but it's limited by the combined wattage. My concern is that the box for the 5770 says the minimum required for a 12V rail would be 40A (to be fair, the ASUS box also says it requires a 500W PSU when it really needs 450W by ATI's specs).

To top it off, I found another single post in a PSU/5770/XPS thread where someone simply posted "I've got a 5770 in my XPS 420 with my stock 375W PSU and it works no problem." I can't find the thread again to link it, but that was the gist of it. By the sticker on the side of the stock 375W unit, it wouldn't have anywhere near the required 40A rail...

Confused thoroughly,
Nate

A:Is my MoBo dead or is it power or something else?

Same thing

My computer is doing the same thing, except, I switched my hardware from one case to the other and power up was attempted, a fan would spin, a led would pop on and nothing else. I switched back to the original case and the same thing happens. The RAM led is lit on the motherboard and network port is lit and flashing so I know the MOBO is getting power, but it just does not want to power on the whole way. I had the same problem when I first built the box, but it was resolved by another friend when I wasn't looking and I neve asked the technical details on how he fixed it. My specs are below.

MOBO: Gigabyte GA-8IPE1000 Pro Intel P4 3.0G HT
VC: ATI Radeon x800 PRO 256MB AGP
PSU: Turbolink Switching Power Supply (stock with full tower)
Memore: 1.5G of Corsair Value Select and HP stuff
HDD: Seagate Barracude 120GB

http://www.giga-byte.com/Motherboard/Products/Products_GA-8IPE1000%20Pro%20(Rev%201.x).htm

I have fooled with the front panel wiring to see if that is the problem. Tried powering on sans video card, soundcard, HDD, fans, etc. I am completely lost. Cleared CMOS as well.

Any help/advice would be greatly appreciated.

i bought the GIGABYTE GA-EP45-UD3R a few days ago. After reading some reviews, I noticed someone said something about having an up to date power supply. I looked into it and saw that this motherboard requires an 8-Pin and 24-Pin power cable. I currently have the power supply that came with this JPAC Computer case. (i am very aware that this case is a p.o.s. I only bought it because of its price on ebay). The power supply in the case only has a 4-pin and 20-pin power cable. Do i need to buy a new power supply? Or can I use one of the 4-pin to 8-pin and 20-pin to 24-pin adapters like this one.

Here are my specs.

I have an Emachines Etower 500i that doesn't power up. When the power cord is attached the fans on the ps and cpu spin and then stop. Then it won't do anything, until the power cord is unhooked and hooked up again. I've tried a different psu and motherboard. If I unhook everything from the mobo except the power switch connector, it will turn off and on with the power switch. But as soon as I plug any drives in the power switch won't turn it on or off and the power cord has to be unplugged and plugged back in then the fans spin for a couple seconds and stop again. If the memory is in when I plug the power cord in I get 2 quick beeps and then 8 more beeps. Everything I've seen about these symptoms points to either ps or mobo, but I've switched both with the same results.
 

A:power supply or mobo?

You may have had a catastrophic failure that has taken out the processor, ram, video card(if not integrated, and/or the hard drive or CD drives. You'll need to have those parts tested or swapped out to narrow it down.

Try this;

Disconnect the machine from the power source, and press the Power On button for about 10 seconds to drain any residual charge from the capacitors.

These instructions ONLY apply to INTEL coolers that were shipped with pre-applied Thermal Interface Material or Thermal Interface Compound.

Without removing the cooler take a flat blade screwdriver and turn the locking pins counterclockwise to the unlock position. With all the locking pins loose, without lifting up on the cooler assembly "gently" turn the cooler assembly left and right a couple of times (Just a couple of degrees each way). Turn the locking pin assemblies until the notch on the locking pins is perpendicular to the heatsink. Re-align the locking pins with the holes in the motherboard. Push down HARD on 2 pins at a time diagonal from each other, until all 4 pins are fully down and locked. After all 4 pins are down and locked push down HARD on each pin individually.

Re-connect the power source, power on the machine and see if it will boot.

I'm trying to recycle my older computer parts to build another one. I picked up a Foxconn 915A01 motherboard today but it uses a 24-pin power supply and I have a 20-pin. As I understand it the other 4-pins are for the PCI-e slots (which I won't be using). I've read the manual can't seem to find anything about using a 20-pin.
 

A:Using 20-pin power supply on 24-pin Mobo

you are usually OK using a 20 pin supply on a 24 pin board, you do have to pay attention when fitting the connector and DONT FORCE IT, if it doesnt fit then you have the incorrect orientation, rotate and try again!. The connector shape will prevent you from connecting it wrongly tho

My neighbor has a desktop that is having a strange problem. If the PC is shut down it will not start properly. The green light on the back of the PC (power supply) is dim and blinking. In order to get it to start, you have to open it, remove the plug from the PS to the MB. Then while power is on, plug the PS back into the MB and move it a bit until the green light is solid. Any ideas as to what it may be?

sounds likely that your power supply went out on you, try swapping it with a spare known good one. if you haven't the parts on hand, i reccomend taking it to a local pc repair shop, where they will have plenty of parts and experience to solve your problem. good luck.

OK so this has been going on for a bit: my machine is running fine, sometimes for hours, but then all of a sudden the screen goes black and the monitor switches to power saving mode. The computer is still running but can't be woken up and has to be restarted.

What I've tried:
1) New video card- it was a good excuse. Went from 9800gtx+ to HD 4870.
2) trashed Vista, clean install of Windows 7 beta 7000.

3) in control panel, turned on "balanced" rather than power saving.

The machine: MSI P7N 750i motherboard. 4 gigs of corsair xms ddr-800. Xfinity 600 sli PSU. E6850.

So I am thinking next step is to replace the PSU....but I thought I'd check here first for ideas as the old budget is hurting a bit and a decent PSU does cost.
Your thoughts?

A:pc not power up but led light on mobo is on

Have you tried booting up the system without the ram? Take the ram out and see if anything happens when you turn on the puter. However, it could also be that you've accidentally damaged the mobo while swapping the ram... If that has happened, it might explain why nothing is happening and you will have to replace it..

Try removing and re-fitting the PSU connections again and also remove and re-fit the memory and CPU. If that does not work, then your mobo is most likely dead.

Hi

Going for my 2nd ever mobo install,
this one into a new case & new power supply.

Going ASUS P4C800-E and a P4 Northwood

Reading up on the board, I noted it might be
a good investment to make sure the power
supply voltage is stable, to avoid spikes.

I then found a main power cable that has a
large capacitor wired into it to absorb voltage
spikes.

Is this a valid concern and a worthwhile investment?
Only a few $.

Thanks!
 

A:Mobo power stabilization ??

If $ is not a problem this capacitor cannot hurt.You did not state the make and model so I can't comment .
Generally , any brand name power bar with voltage surge protection will be fine .Look for the brands that offer a warranty covering your equipment replacement is a good bet.

What power supply are you using?

Did you first connect all of your hardware outside the case and do a burn-in test?

Remove everything from case.
Grab motherboard box.
Place motherboard on top of box.
Connect everything.
Power up board.
Let it run for a couple hours like that, if nothing asplodes put it back in the case, if it don't work, you probably have a short behind the motherboard.

Hi, I am tying to sort a PC for a friend. The PSU appears to be fried, so swapped that for a spare one. The spare provides power to the mobo in that the on board LED lights up, AGP powered fan spins up, as does the CPU fan and the case fan. However this is as far as I get, the is no video output. I am wondering if the mobo is fried too. One other thought is that the 20 pin connector on the original PSU contains 20 cables, whereas on newer PSUs there are only 19. Could it be that as the PC was built with a PSU which provided 20 cables into the 20 pin connector that a 20 pin connector fron a newer PSU which only contains 19 cables might not work? Sorry if this is a bit garbled.

earth

i have had that problem so many times. all of those times it was because the motherboard was earthing. something about the mobo touching a part of the case is shouldnt. but to make sure the mobo hasnt blown take it out the case altogether, sit it somewher (say on a pillow) , put power in2 it an get a screwdriver, an uno the little bit wher u plug the power cable switch, along with teh hdd light, reset switch (i dont know the name of this bit,jus aloada pins lol) put a screwdriver in there, just so its touching the bits of metal and teh mobo should start up. if it doesnt the mobo might have blown. if it does the mobos fine. you just gotta be careful when your puting it in. try and test it everytime you put a screw in, and use risers if you can. everytime i have had this problem i took out the motherboard an put it back in and it was fine.

p.s. it dont matter when or how it happens, you dont have 2 hit it. what im saying is you could be sitting and for no reason it powers off and wont start back u, liek what happened to me. try what i said above and you should be fine :grinthumb

I have a ASUS P6T mobo with a i7-950 CPU.The mobo has a 8 pin power cable connection for the CPU, but 4 of the pics are covers. Not 4 on one side, but 4 on one end.

I have the machine running, all is well, but I'm wondering if I should get an 8 pin cable and use that instead of the 4. I don't do any gaming or real heavy usage projects. A #2 pencil and a sheet of lined paper would do most of what I do.

I have looked on the ASUS forum but not found a positive answer one way or the other, maybe there isn't one.

1 x 4-pin ATX 12V power connector


Are you saying your power supply doesn't have either? What power supply are you using?

Hello, i have some simple questions. My system randomly turns off. no blue screen. No crash dump. no windows shutdown screen. This isnt really about the shutdowns.

1 - What happens when the 4pin connector of a 20+4 pin mobo power plug is disconnected

2 - Does the 4pin connector give more stability to a pcie2.0 x16 Graphics Card?

3 - What damage could have been done?

Ive swapped the graphics card out with a Power Color HD4850. The shutoffs happened with both.

I have four ram chips. i took out 2 and it still shutoff. Im now trying the other two.

Thank you for your time.

A:4pin of a 20+4 pin mobo power was n0t plugged in. What happens?

To answer your questions, I really don't know. But, I would suspect the +4 pin will supply more power to the motherboard. The 20 pin will supply enough power for it to run but not quite as much as it should have. I would not worry too much about any damage to the board. The GPU gets most of it's power from the pcie conntections, but the extra 4 pins may help. As far as the memory, I would suggest running memtest86 to test the memory. The link is to a tutorial on how to run it. You are looking for bad ram sticks or defective dimm slots.

It would help no end if you could write intelligible English.

You don't say what your old motherboard is.

The new motherboard probably has a new 24-pin power connector instead of the old 20-pin connector.

The new board is: "8S661FXMP-RZ is a highly value-oriented P4 platform with excellent performance and impressive features. Empowered by the latest SiS 661FX/964 chipsets, and Gigabyte's R&D..."

I've wanted to know the difference in useing ATX power connector and ATX 12V connector. my mobo and psu both support ATX and ATX 12V. standard atx i kow has been around for awhile. so what the difference?
 

A:Solved: Mobo Power connector

1.2. Key Changes for ATX12V Version 2.0 and later as Compared with ATX and Pervious Versions of ATX12V Power Supply

This section briefly summarizes the major changes made to this document that now defines ATX12V power supply. With the move to 12V voltage regulators for the processor, ATX guidelines for 5V as main power are no longer provided.

1.2.1. Increased +12 VDC output capability
System components that use 12V are continuing to increase in power. In cases where expected current requirements is greater than 18A a second 12 V rail should be made available. ATX12V power supplies should be designed to accommodate these increased +12 VDC currents.

1.2.2. Minimum Efficiency
Minimum measured efficiency is required to be 70% at full and typical (~50%) load and 60% at light (~20%) load. New recommended guidance has been added to provide direction for future requirements.

2.03 is the current version of the ATX Specification as of this writing. Future references to the ATX Specification in this document imply version 2.03 or later, as applicable. ATX12V Power Supply Design Guide 8

1.2.3. Main Power Connector:
The 2 x 10 main power connector has been replaced by a 2 x 12 connector. This was made to support 75 watt PCI Express*requirements. Pinout assignments are based on the SSI recommendation.

With the added 12V, 5V, and 3.3V pins the need for an Aux Power connector is no longer needed and the guidance for this connector has been removed.

1.2.4. Separate current limit for 12V2 on the 2x2 connector:
The 12V rail on the 2 x 2 power connector should be a separate current limited output to meet the requirements of UL and EN 60950.

Here's the document that may explain it better: http://www.formfactors.org/developer\specs\ATX12V PSDG2.01.pdf

So I ve been having some problems with the power button I m not sure if its the mobo or the cases problem? (mobo) Power button button itself Obviously i hope its the button but everytime I want to turn on the PC i have to press the power button several times to make it turn on It almost always requires - button pushes for it to recognize i want it to turn on Any ideas if this could be a button mobo or maybe even a psu issue thx for any help EDIT Power button (mobo) problem? I have checked the PSU with SIW to see if there s any psu related problems All rails are reporting within almost EXACT specs Infact I have never seen the rails look so close to the min-max as they do before now So it can t be the psu EDIT I m not sure if this will help in any way but I ll just say it Upon pushing the button down the CLICK on the button thats on the case is pretty loud There has never been once a time where the click has never came out It has always clicked of the time Its just to rule out any possibility someone might think that the button might not be making sufficient contact with whatever it needs to turn on the pc nbsp

A:Power button (mobo) problem?

Which case brand do you have. We have seen power switch problems with at least three popular brands of computer cases..
Unfortunately, we have found no obvious fix because the case makers to not repair switches or replace parts.
On some a small plastic part breaks. On others the switch grounds itself against the case wall or panel.

I just went way out on a limb and bought a new ASUS A7V8X-X mobo with an ATX Case including an XPower LC-B350ATX power supply. I have all jumpers at default. The CPU fan appears to be seated correctly and is plugged into the mobo. When I turn on from the switch on the power supply i get nothing. when i go to the front panel and hit either the reset or power button i get nothing. i checked both switches and they have continuity when depressed and lose continuity when released. i assume this is correct. i read in one of these threads about someone that said the mobo book was wrong for plugging in the front panel stuff and he used the markings on the board instead. my board markings match my book. do i need to change any jumpers? i dont even get the led light on the mobo to light. very depressing.

Hi All,

You may have seen my ramblings earlier on a six month old thread.... :blush:

Well, I've sorted out the case to motherboard wiring best I can but when I power up, the CPU fan spins for less than a second then nothing.

I have tried an alternative ATX power supply (300W, I think the original was 250W) which I know works in another machine but with no joy.

Can anyone give me a few pointers to look at our is something on the motherboard goosed.....

My computer just shut or mobo you power supply problem think? do what off by itself last week And it would not power back up I stripped down the computer to the bare essentials one stick of ram video card etc Through trial and error I have noticed that the PC will power up again but only if the keyboard is not plugged in When I try to attach the keyboard in the mobo or power supply problem what do you think? off position I start to hear weird fizzing noises Nevertheless with the keyboard in it will not power up Also noticed that the floppy mobo or power supply problem what do you think? has no power to it I cleared the CMOS JUMPER as well but that did nothing I have an AMI bios I got beep followed by although there was a very slight pause between the nd and rd I have checked out AMI s codes and everything seems to point to the mobo Has anyone ever experienced this sort of problem before Do you think my mobo is the problem or do you think it may very well be that the power supply is creating this problem Any input would be greatly appreciated thx nbsp

A:mobo or power supply problem what do you think?

Considering it's much easier to swap in a keyboard, I'd try that first. Are you getting video out? If BIOS is beeping this usually means it knows it can't write to the monitor, so it beeps fail codes instead. Although some BIOS will not complete POST past whatever fault they find, in your case the keyboard.(my guess).and therefore won't load video driver.

If it's not keyboard, then it very well might be the mobo connection at the keyboard or something in the interface chips dealing with the kb. In that case it's new mobo required. But before I did that I would try the PSU, again relatively easy to remove/install new one. What kind of computer is this?

A:Mobo, Processor, or Power Supply? Or all 3??

You can approach this in two ways. One is just to replace the PS. The other would be to remove everything non essential for posting. Just leave the HS/fan/CPU, RAM (if you can or it applies one stick at a time) and video adapter. If that doesn't work try the same set up with the MB out of the box on a non conductive surface. Then when it still doesn't work replace the PS.

The fans turn about a 1/4 of a turn every 7 seconds like its trying to boot up but nothing. Im using the old power supply (250w) but im only running a harddrive and cd drive. Im thinking thats the problem but if anyone has any ideas let me know!
 

A:New Core Duo And Mobo Wont Power Up?

There's a 4 or 6 pin molex power connector near the CPU that many people forget to connect. Are you one of these people? Maybe your 250 watt power supply doesn't have the molex connector, does it?

It might. My 24 pin MSI motherboard will accept a 20 pin power supply although you need to know which end of the connector to line up. Check the manufacturer's website if you don't have your motherboard's manual.

That said, you could also use a 20 pin to 24 pin adapter. About $4.00 or so.

Burnt smells are really not a good thing, and indicates that your PSU is pretty much 'toast'. Get it. "BURNT" "TOAST" HILARIOUS!!

Sorry, that was really bad.

Anyway, your PSU is not safe to use anymore. Get a new PSU and see if it solves the problem. If it does, then you're good to go. If not, it's likely that your motherboard was damaged as well. Processors rarely fail, so I'm more apt to believe that it's the PSU and/or motherboard.

Hi
I have my motherboard sat on a cardboard box attached to hard drive with OS installed,graphics card,2 sticks of memory,keyboard and mouse and everything seems to be working fine apart from powering/starting up problems.
On pressingthe power button on the case sometimes it starts sometimes it doesn't.
I have also tried another PC case thinking it might be a dodgy power button but the same thing happens with the other case.
Sometimes i have to disconnect the power from the wall socket before it will start up.Once it starts up it is absolutely fine and stays on with no problems.
Do I have to change something in the bios
The mobo isn't a new one it is a MSI 6526 ver 3. and I have a pentium 4 1.8gHz CPU
Any advice would be gratefully appreciated
Thank you
 

A:Bench test mobo, power-on problems

Always disperse the internal voltage (by removing the power cord, then holding in the ON switch for 30 secs)

Make sure to disconnect everything internally (ie all addon PCI devices, and CD/DVD connection and floppy connection (if you have one) from the motherboard

Actually here's a good BenchTesting guide.

One last possibility, I have had faulty case and CPU fans cause boot up issues.
And faulty Power Supplies (doing strange things)

You should also reset CMOS to defaults

I purchased a new computer but thought I would just try to fix the old one....Replaced both Power and new MOBO and I believe I put all the jumpers on correctly(also removed old CPU and put in new MOBO) Powered it up and CPU fan comes on...No power to the CD or DVD and no image on the monitor.

Questions: Did the CPU go as well? How do I determine if I need to buy a new CPU?

Does the CD and DVD power go through the CPU first or do I have some jumpers put on incorrectly?

Thanks for assist
 

A:Repairing a emachine 2895 MOBO and Power

Usually when the PS in an eMachine goes bad it sends too much voltage through the ATX power connector so there is a chance the CPU was damaged. Call around and see if any shops in your area can test CPUs. Also make sure your new mobo is compatible with the old CPU. Also try clearing the CMOS on the new mobo.

If I need a new supply, is 300 watts "better" than 235w or 200w? If I need a new case, any thoughts on what's the best value? Does an ATX power supply fit into some AT cases (if there is such a thing) or is a dedicated ATX case/power supply needed?

Thanks to anyone taking time to offer an opinion.
 

A:Will old AT power supply and case support new ATX mobo?

you will most likely need a new case and power supply. Some AT boards will take either a AT or ATX power supply but I have not seen an ATX board that will do both. There may be some exceptions but it is a good bet that you will need to buy some new equipment.

This is a long story I have a Amptron M MR with P cpus, mobo? screens: power, or blue EB and MB DIMMS The system is also configured with a single IDE disk for boot and a highpoint SATA RAID controller with GB drives running RAID Also in the box are three NICs and a dual-head Matrox AGP card The machine has run reliably since May this year and the case had hosted a dual-PPro board reliably for a blue screens: cpus, power, or mobo? couple years prior to that The machine dual boots Win Pro and RedHat Windows got infected with some Nachi variant weeks ago so I cleaned it and installed SP Since then the machine blue-screens in Windows and hangs in certain apps on Linux The Windows blue screen messages vary sometimes I get STOP F messages but more frequently I ll get quot Hardware Error Contact your vendor quot or something like that Linux just locks up no reboot or crash message I ve found that if I swap the processors the system doesn t bomb as often blue screens: cpus, power, or mobo? and if I remove the original CPU of from the system it s much more reliable at least it s been up for nearly hours under fairly heavy load Before I start buying replacement hardware I want to solicit some opinions I m wondering if the power supply has gotten flaky if the motherboard is losing it or if I need to buy another pair of processors I can offer more information later I m at the office now and don t have access to the hardware nbsp

Unless your Dell is quite old, it will have a standard ATX power supply. The drive bay power supply is a great idea. It just might work perfectly for you. The PCPower supply would work too

Aloha,
I have a ASUS P4C800-E Deluxe mobo with a Antec SL450 watt ATX12V power supply and I messed up. My 3 1/2" floppy didn't work so I checked the small 4 pin power cable to see if it was ok. I removed the plug from the floppy and reconnected it. I couldn't see very well so I connected it 1 pin off on the back of the floppy and powered up. Nothing happened so now the fun begins. Is there a fuse on the mobo or power supply?? I know that the start button connects to the mobo and somehow it activates the power supply so did I blow the mobo or power supply? Is there a way to check the power supply without it being connected to the computer? I just hope that I didn't blow the Mobo and power supply. All suggestions will be greatly appreciated. TIA

Mahalo,

my PC did not power up when I pressed power button. The motherboard has lights (leds). turning power on at psu lights up leds. pressing power on pc button fires up the fans for < 1 second and then nothing.fans stop, boot process doesnt proceed but lights remain on board.

So I buy a new psu (another 800 watt). I unplug all but bare essentials on board. same issue. I then take out the 8 pin adapter (so only the 24 pin is connected) and leds remains on and boot up starts (yipee). I then put the 8 pin in again and it fails in the same manner as before.

Gigabyte GA EP45 DQ6 mobo
4 hard drives
2 dvd
intel q550 ( I think)
4 x 2 gb RAM
800 watt psu

any idea where fault lies? I assume board.

A:Power button not working... mobo issue?

Not the switch. Could be the motherboard or PSU, but I don't have any good insight.

I would unplug the PSU and flip the 120/240V switch to 240V, then flip it back before plugging it in. To me, this doesn't make any logical sense, but over about 16 years of playing with PCs I have seen it work twice.

When i try and connect the 4 prong power source to the motherboard, the fans and lights quickly flash and stop spinning after about 1/4 of a turn.
When i disconnect the 4prong power cable, and only leave the larger power cable in, the pc turns on like normal and stays on, but displays no picture on the monitor and also the mouse doesnt light up?
Am i right in thinking that the processor has broken? and that the pc needs the 4prong power source to function properly?
please help,
thanks
 

A:My pc only turns on when the main power is connected to the mobo.

You should have to have all of them plugged in. Did you miss another power connection on your mobo that gives power to the CPU?

I have a Compaq Presario 2100. well the power jack broke off the motherboard, while trying to solder it back in place, one of the prongs bent, so I was taking it out again to start over, when my friend bumped into me. I accidently pulled it out of the motherboard. While inspecting the prongs, it looks as though a copper looking "sleeve" was still soldered to the prong. Is there anyway to fix this?

Also, the original jack was lost. I have another one, it's not a replacement, but it fits the plug. How can I solder this to the mobo for it to work?

Please help me.

A:Installed new cpu and MOBO - power constantly on / wont do anything

Welcome aboard Paul, hopefully we can help. First things first, when you change out a motherboard (mobo) it requires, under most circumastnces, that you do a complete, fresh install of windows. Sometimes windows will accept a new mobo and CPU just by loading the new drivers but then there are a multitude of little problems that plague the user forever.


So a few questions:
1. Did you reload windows after fully formatting the Hard Disk Drive (HDD) or just plug the HDD in and load the new drivers?
2. Did you install this in a OEM (Original Equipment Manufacturer) type case (like Dell or HP) and if so is this the original Power Supply Unit (PSU)?
3. What kind of video card are you using?

If this is in a Dell case as an example then that may be the problem as their cases are not wired like others.

Hello all, My question relates to this motherboard -Asus cuv4x-c.
The orignal psu did burn out, I pulled it apart to find scorch marks around some of the components I dont know the history of this board I assume this is a power surge problem!?
I connected it to 500w Gigatech atx, connected the cvd-rw, harddrive, floppy and power supply to the board itself. Switched on the power and no l.e.d s lit, the fan in the power supply started but the fan on the proccessor did not, there are no other fans in this box. On inspection of the board( after dissconecting from power) there seems to be no obvious signs of burnt out parts, none of the Solder has melted or scorched, the circuit board looks intact.
What is the best way forward here- test with multi meter perhaps, what else should I be looking for?? Any advice would be appreciated. Thanks in advance.
 

A:Asus cuv4x-c. mobo wont power up.

My guess is that you've had a power surge or lightning strike that has fried both the powersupply and the motherboard. This can also happen if you plug something into the board (e.g. a PCI card, or stick of RAM) while power is applied to it, as this may short it out. There don't necessarily have to be any visible scorch marks on the board for it to have been damaged by a surge, the powersupply took the brunt of it. Do you have insurance?

Hi, I recently picked up this computer second hand. 

Every so often, sometimes after 6 hours sometimes after 36, the computer will act as though it has lost power. The power button is unresponsive and has no indicator light showing, the status LEDs on the power supply and the ethernet port are solid (I did not note what colours they were, I shall update next time it happens).
To get the machine to reboot I have to remove the power cable and then hold the power button until the PSU and network light go out (They turn off suddenly rather than dim). After this I can reattach the power cable and the computer will boot and act normally for another period of time.

Any ideas?

A:Solved: New mobo with power no post or display

The Asus Uk site says you need Bios version 0705 or later to use the FX-6100 Cpu.

There have been 4 Bios versions, 0404, 0506, 0705 and the latest 0813.

So I think you are probably correct and your Bios is too old for that Cpu.
Unfortunately I don't know of any way you can find out what Bios you have now if the PC won't POST.
So I think your plan of buying a cheap compatible Cpu and then flashing the Bios is your best bet.

I'm in the middle of assembling a new computer (first one) and I just realized that my current PSU does not have an 8-pin ATX power connector for the CPU on the motherboard. Is it safe to use a 6-pin and half of a 4-pin connector to power the CPU? I've attached a picture and as you can see half of the 4-pin is just hanging off the end.

A:Using a 6pin and half of a 4pin for 8pin CPU power on new mobo?

Well, first you get the annoying lecture : If you are building a new system the power supply is the LAST thing you want to skimp on. You should buy a new, modern PS for the system.

Now that's out of the way.

There is nothing technically wrong with how you want to do it. The power supply delivers 12v to each yellow wire regardless of where they actually go. So if the MB needs four 12v wires (and 4 black grounds) to run you can accomplished that your way.

There could be a problem - resulting in odd behaviors and system problems - if the 12v leads came from different 12v rails on a multi-rail power supply. This could result in "dirty power", where the amperage (as opposed to voltage) is not the same across all 4 wires at the same time. This could even happen in a single rail system, depending on the internal circuitry of the PS and where those two separate wire bundles connect.

The only thing that concerns me from your picture is that 3 of the yellow wires are in the back row and that one (plus the extra one hanging off) is in the front row. This seems to be a problem with polarity and I am surprised the system runs like that. I think that all 4 yellow wires should be in all the rear slots.
