PC build doesn't power on

Q: PC build doesn't power on

Hi guys I ve spent today building a pc for myself However on pressing the on button there s no reaction at all My machine specs are M B - Gigabyte GA- A-UD Processor - AMD RAM - Corsair Gb DDR Case - Zalman Z Graphics card - Gigabyte HD PSU - Corsair CX M W Wi-fi card also installed but can t remember the name and seem to have temporarily lost the box in a pile of packaging So far I ve checked the CPU and motherboard power sockets the wall plug sockets and the power cord to my PSU I ve also checked the connections between my case and the motherboard and these all appear to be correct on power build PC doesn't As part of this final point I switched the power on LED with the power button they both originate from the same location so thought they may be mixed up Anyhows I got a solid LED which suggests to me that a there s power running through the switch circuit and b the pc isn t booting when told to as a PC build doesn't power on solid LED would indicate PC build doesn't power on circuit completion which would be the equivalent of holding in the on button If anybody could shed any light on where to go next I d be eternally grateful currently searching the house for a paperclip to test the PSU nbsp

I have an ASUS notebook running windows 7 64-bit. I am using the QuietOffice power profile, however the screensaver won't kick in no matter what I do, and the display does not turn off even though I set it to be after 5-minutes of inactivity. I don't know if there is something running in the background... I have turned off my usb wireless mouse, and nothing....

Any ideas?


A:HELP: power option doesn't work - screen saver doesn't start!

This is another case of factory bloatware interfering - in this case a useless factory utility overriding Win7's superior built-in version.

Googling the Quiet Office feature of Asus there are multiple reported problems. Best to default to the Win7 built-in Power Options in Control Panel. Set up a Balanced Plan unless you're a gamer then use High Performance.

Here are other tips for cleaning up factory bloatware

Hi, since the power of my Y3P with display at max birghtness does not hold very long it would like to build a powerbank for it. Since the Power Adapter is 20V 2A I wonder if I could put 4 x 5V (2A) Power Banks in serial and have 20V and enough amps to fuel the Y3P. I also ordered a cable with the right plug to connect to the Y3P. However it has 3 wires inside. When mesuaring with a meter one is ground and two deliver about 5V. How could that be? How would you wire it to power the Y3P. Does anyone has any idea?PS: I know this is gonna wipe warranty.

Hello everyone - I have just assembled a new build It will not power up I need a suggestion to figure out if the problem is the case or the motherboard This is a mini-itx build power-up: power New or Build MB? no supply case's The case is New Build no power-up: case's power supply or MB? Linkworld LC - B This case comes with a volt watt external laptop-style power supply that plugs into the rear of the case just like New Build no power-up: case's power supply or MB? a laptop power supply plugs into a laptop - a barrel connector Inside this power connection connects to a power supply component that is not like a regular ATX power supply but is on a printed-circuit board New Build no power-up: case's power supply or MB? mounted on the case This has several capacitors and other stuff From that comes the -pin and -pin power supply lines for the motherboard I assume the -volt power supply for this external power supply unit is right since it came with the case It was watt The processor is an IBM t with TDP of watts Lower-powered CPUs can be put in a small so I assumed the power supply might be under-powered I ordered a -watt volt power supply with the right size barrel - and same polarity pos inside The MB is an ASRock H MV-ITX It is mini-itx form factor Still same problem Everything is connected correctly When I press the power-on button an external CD drive I have plugged-in spins up for a while But no power light comes on in the front of the case there are no POST beeps the fan for the CPU does not spin up No other signs of life So power is getting into the MB - the external CD drive is plugged into a USB socket in the rear panel of the MB After trying a watt and watt power supply I believe the problem cannot be the power supply cord Can it be that I have too little load I don t think so I plugged in another mm fan and an ol-fashion floppy drive just the power connection to add more load - same thing no power-up no POST nothing but the CD drive will spin up when I open-then-close it yet again So here is the help I need what else can I try -assuming the MB and case are fine is it more likely the case power supply is bad or the MB --Thanks nbsp

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

The system's fan was very loud so I put in a new power supply and then everything booted up fine. Unfortunately, that didn't solve the problem. It was the Motherboard fan making all the noise.

So, I put the old power supply back in and now the system doesn't power up at all. I checked all connections & I replaced the power cord and tried a different electrical outlet.

I even put the new P/S back in and nothing changed. It still doesn't power up. It's dead!

Any suggestions?

Do you mean the CPU fan ?
If so then I wonder if the CPU has been cooked

I would start by dispersing all internal voltage.
Detach the power cord
Press the power button in for 20 seconds
Re=attach the power cord
Try again

If it didn't fix then remove all addons, usb devices really anything attached (except screen and keyboard and power cord)
And try again

If it didn't fix then, confirm all internal connections are secure (even detach the dvd drive{s}

If it didn't fix then try disconnecting all fans (what !) for about 10 secs (turning on) I once had a fan of all things, that stopped my computer from turning on (unbelievable, I know)

Lastly, check the CPU for heat damage !

Everything turns on, fans and everything. It's a completely new build. No input detected from a Samsung monitor.

I've swapped ram sticks to see if one of them is dead

Hey guys, I currently have Windows 7 Ultimate (RC Build 7057), and was thinking of replacing it with 7600. I don't have the option to back up my files, and was just wondering.. is the jump from 7057 to 7600 worth the loss of data? What features does 7600 have that 7057 does not? Any answers would be appreciated. Thanks

Basically just what the title states I purchased a Gigabyte Sumo Y and finished completing the build Only issue is the only way I was able to plugged Fan/LED into cable build doesn't PSU with New launch boot it up the first time was by unplugging the plug which connected the case fans and LED I believe to the PSU There are case fans Front top back and side and Fan Headers on the Motherboard As a note before I start all the other components are working The PC booted GPU is going good CPU and it s fan are good as is the power supply fan I New build doesn't launch with Fan/LED cable plugged into PSU m no expert at doing this as it is the first build I have ever done I m not sure what to connect to what and all the manuals and googling have shown up with nothing After unplugging everything I initially did that I thought would work the fans the only things left in the desktop hanging loose are a single Male Female Molex power cable It has male on one side and female on the other near where all the Power reset fan speed buttons come from There is also another male female Molex power cable hanging off the side panel of the desktop which includes a fan and LED light One more cable hangs off the side panel which seems to be an LED plug but it seems that it is only for extensions for lighting The cables I have left are cables which each have on them a -segment power plug four female Molex power cables and a -socketed plug which I believe to be a Fan Header The other cables which I have left and I found odd are the two cables I got with my graphics card There are two of these cables and each of them have an -segment power plug and two male molex power cables which only have prongs in them despite having room for a fourth So with all that would somebody be able to help What should the setup be for the cables I have Is there a reason why it wouldn t boot with that power cable plugged in Sorry if I overdid it but just trying to give the most information possible Thanks in advance nbsp

A:New build doesn't launch with Fan/LED cable plugged into PSU

1. Welcome to Tech Support Guy
2. It is impossible to advise you until we know the make of motherboard and its full model
and the make of PSU and its full model
3. Re this
Is there a reason why it wouldn't boot with that power cable plugged in?

Click to expand...

presuming you refer to the case fans and led, my guess is that you have a wrong connection possibly live to ground
You say there are four case fans and three fan headers on the motherboard
I would suspect that one of those fan headers on the board is for the CPU fan

I tried to get a hit on gigabyte Sumo Y at the gigabyte site but cannot do so - to get spec
As to the rest of your post I appreciate that you have done your best to describe the connections available and the connections from the PSU, but it is as I said impossible to advise on those details

The cables with the graphics card are provided to cover the connection for graphics power when the PSU does not provide two 8 pin graphics power leads
The reason the molex only had three pins is because the fourth pin on a molex is 5v and tat is not required for graphics power

You have to reinstall from the chrome website, thereby getting the latest Chrome version. You will keep your Bookmarks automatically.

A:Build 14251 - Chrome doesn't work

After totally uninstalling Google Chrome including all registry entries and folder containers in normal and hidden folders, and the reinstalling Chrome, Google Chrome does not open. There is an exception in the event viewer, the contents of which means the following:
Computers have limits, they cannot divide a number by zero, nor read memory that isnt there, (and lots of other things).

They use a generic mechanism called Exceptions, to signal the software that it cannot do the operation it was requested to do, and some information as to why not.

Straight out of section 3.1.9, table 3-2 of Intel Processor Instruction Manual
0 #DE—Divide Error DIV and IDIV instructions.
13 #GP—General Protection Any memory reference andother protection checks.

Peruse this excerpt from the IA-32 Intel? Architecture Software Developer's Manual, Volume 3: System Programming Guide (bear with me, it gets better)


Exceptions are classified as faults, traps, or aborts depending on the way they are reported and whether the instruction that caused the exception can be restarted with no loss of program or task continuity.

Faults A fault is an exception that can generally be corrected and that, once corrected, allows the program to be restarted with no loss of continuity. When a fault is reported, the processor restores the machine state to the state prior to the beginning of execution of the faulting instruction. The return address (saved contents of the CS and EIP registers) for the fault handler points to the faulting instruction, rather than the instruction following the faulting instruction.

Traps A trap is an exception that is reported immediately following the execution of the trapping instruction. Traps allow execution of a program or task to be continued without loss of program continuity. The return address for the trap handler points to the instruction to be executed after the trapping instruction.

Aborts An abort is an exception that does not always report the precise location of the instruction causing the exception and does not allow restart of the program or task that caused the exception. Aborts are used to report severe errors, such as hardware errors and inconsistent or illegal values in system tables.

a #GP is a general protection fault. That means the program tried to access memory that is 'protected', it could not, and as you read above is handed to the fault handler.

Now.. If you've been in the game since Win98, you may have seen a GP_FAULT once or twice. Same thing, only now in NT/XP we get DrWatson complaing about an ACCESS_VIOLATION. This begs the question, what did it try to access that was a violation of normal runtime?

The operating system knows that programmers make mistakes, and make a special DMZ/No mans land at address 00000000 through address 0000FFFF, so that programs who try to reference NULL (a C programming way of saying Zero or Empty) will fail, rather than corrupt themselves and die horribly after corrupting your data.

Prove it, you say?? Can do.. i fire up my trusty debugger and examine this memory

A:New build - no power?

This sounds suspiciously like a dead motherboard. But the noise from the PSU it not something I have heard before.

Strip the PC back to the bare minimum of components so all you have connected is the mobo, PSU, monitor (use the onboard graphics if it has any) and the on/off reset switch. Remove the RAM, hard drive, CD drive/s, keyboard speakers etc. This should give you the POST screen when you switch it on. If it does not do that then the mobo or CPU is faulty. I would then return both of them for replacement.

It is possible that you have accidentally caused some damage from static, you should always earth yourself when touching anything inside a PC and the wearing or a wrist strap attached to an earth point is highly recommended, they are not expensive.

Check that your system isn't being shorted out by any of the motherboard mounting screws. Try testing outside of the case if in doubt. Other than that it sounds like you could have a DOA component.

Motherboard: DP35DP
Power: Neopower 650
Case: Antec P182

The pushbutton power switch must be pressed in twice to get the unit to power on.

Calling Antec they say to a) update bios or b) try another power supply or c) change the motherboard.

All of which seems extreme, with everything else ready to go now. I was thinking the "2 step switch" was a safety feature so the unit could not be accidentally turned on but no such luck.

What is the likely problem?

A:new build - power up problem

Re-check all your power and switch connections to the motherboard, unplug then replug them a few times.

If no joy, time to start suspecting a bad case switch, mobo, power supply.

Just finished putting together a PC. This is my first time, but I'm pretty confident I know what I'm doing.

Everything connected and I turn on the power button, and nothing.

My only thought is the power supply. The 24 pin connector is missing one of its pins. Is this normal? I took a pic so you can see what I mean. It's like the wire was never put through the hole if you know what I mean.
Thanks for the help.

Hey everyone,

I built a new system (or rather am in the process) I just got my mobo (EVGA 680i T1). I took it outta it's box, installed the CPU (core2 duo) and heatstink/fan, and then connected the 24-pin and 8-pin power cables from it's awaiting powersupply (750w).

The standby light came on, then when I press the power button (the board power button) the CPU fan / power supply fan came on for a few seconds, then turned off and now it wont turn on at all, though the standby light remains on.

I already tried to reset the CMOS, I haven't tried pop'n out the battery which I read somewhere might fix it, though it seam unlikely. and I tested the power supply which seams to be running fine.

Anyone have any clue what might be going on, and please don't tell me my shiney new board is toast .

You can get 1000watt psu's now, they arent hard to find, check thermaltake, silverstone, I know they have good ones. 850 would probably be minimal for that thing you're running.

I just built a new i3 SB machine with a gigabit board. It was working fine for 3 dys put win 7 on it, but now all of a sudden it just shuts off as soon as i press the power button.

I took the board out and looked at it and i powered it on outside the case but it still does it. Everything looks kosher to me.

A:New PC build turns off within a sec of power on

Could be a few issues, maybe the power button is getting stuck in and just powering down the machine.
Mobo or PSU might be defective.
What I would do is unplug all hardware and just use the bare minimum and see if it still powers down.

Just in the process of building a gaming rig but having problems getting the computer to power up.

mobo - gigabyte Z77-D3H
Processor - i5 3450
Memory - Kingston hyper x DDR3 1600mhz CL9
PSU - powercool x-viper 450W and generic 650w
case - Zalman Z5
Hard drive - Kingston hyper x 3k SSD 120gb

- Tested powercool PSU using antec PSU tester - pass
- Changed over to generic 650w PSU with no power on button. plugged in and hit case power on button to make sure that i had all the connectors in correctly. PSU fans powered up but still nothing through the CPU, no fan, no post.
- removed motherboard from case (possible shorting issues??) again PSU powers up but nothing from the CPU or fan and no posting bleeps?
- added post test card but returns 00 no errors.

Help and comments appreciated.

A:new build - no power to CPU i5 3450

Check the 24 pin power connector to make sure its being fully inserted. Same way with CPU Power (8 pin).

You can get a false positive with a PSU tester as it does not test the power supply under load. You could have the correct voltages with no load but under load one or more voltages could fail.

I have an Abit KN8, AMD 3200 XP, Antec 400w Smart power, 1 Crucial 512 dimm, an ATI 300X PCIe video, a floopy drive, an ide hard drive and a usb mouse and keyboard. All parts are known to be good. As I turn on the power the LED on the board lights, the power supply fan-cpu fan and auxillary fan all spin for just about 2 seconds and stop. The power light in the case stays on. I have reset the CMOS and changed the battery, reset the power cord connection and reset memory dimm. I have rechecked all connections.

Does anyone have suggestions of things to try. Hate to take the board out to look for shorts.

Hi all, seasons greetings to you all.

Have just purchased an Elite K7S5A mo/bo and AMD Athlon XP1800+ CPU, along with a new case and memory module.

The problem I have is that although I am certain that I have followed the build instructions to the letter (this is my third self build compo) the computer will not power up.
I have installed two hard drives, CD and DVD, sound card and video card from my old (working) compo.
Does anybody know if there should be power at the 12V output from the PSU at all times, or only when the power switch is depressed? I am only getting about 0.5V, and nothing at the 5V output.

Anybody any ideas?

Cheers to all, thanks in anticipation

Rebuilding from array of old parts. When old PC was taken apart all I needed was a new case, but I revamped alot and ended up with most everything needed for a new PC leftover. Rebuilt PC from the old parts. Couple of problems here. The new case has elevated areas where the standoffs for the motherboard should go. If standoffs are used the MB sets too high in the case. (Like its designed not to use standoffs. And there were no standoffs packaged to use.) So when all put together sans standoffs, No power. None period, no beeps or anything. The fan in the power supply dons't run either. Does this sound like a problem with grounding on the case or just a faulty power supply?

Welcome to the forum. A daft one but this often happens is there any jumper on clear cmos pins I have know boards come with them set on normally you only put that jumper on for a second or so. Failing that disconnect hd,cd and any addon cards that are not needed with keyboard plugged and try then. If it still doesnt work try it out of the case often its a short when putting it in the case

A:My newly build wont power on

Here's a list to work on from member TVeblen:
Strip it down and then add components back, one at a time, to try and isolate the offending component.

The test (power off, power cord unplugged):

• Disconnect everything externally connected except the mouse and keyboard (printers, USB devices). If you are not using a wired mouse and keyboard see if you can borrow one.

• Disconnect the power and data cables from all the drives inside the computer (Hard drives, DVD/CD drives).

• Remove all the cards installed in the PCI slots including the video card.

• Remove all the RAM sticks (same rules as above).

Now connect the power cord and turn the PC on.

• The motherboard should start beeping. You should get a beep code that tells you there is no memory. This is good, it means the processor is functioning and the motherboard is good so far.

• Now add one stick of memory in Slot A1 and power on. More beeping: "no video card" beep code. This is good.

• Then add the video card and connect it to the monitor. You should get no beeping and you should see the BIOS screens, ending with the message that there is no boot device.

If you get no video then switch the one memory stick installed for another one and test.

Continue adding components one at a time.

If at any point the PC fails the the last component added was the problem one.

If you removed everything and there is only the Motherboard (with integrated video), processor, and power supply to contend with and it does not POST or show anything on the screen, then the problem is one of those three.

If you have tested by using another power supply then you are down to two. CPUs rarely fail, so motherboard is the most likely guess.

Try performing a CLRTC or Clear CMOS as a last ditch effort, and check the 3v battery. Both long shots, but what do you have to lose at this point.

The Corsair line of power supplies is excellent. If you are not comfortable with the 650 try the 750; what do you need from the 12v in amps/wattage for Crossfire? Will you be overclocking?

By the way, love the cpu and 4850's in Crossfire and those WD Blacks have a good reputation. Is your system minus the psu ready to be assembled?

Hi, Guys (And Gals) I'm attempting my 1st PC build and HAVE used the various online power supply calculators... however I'd like to hear some feedback from you all. No matter where I look online I always like to come here to be sure. My specs for the build are as follows:

HDD: Seagate 1TB Serial ATA HD 7200/64MB/SATA-6G

I would really like to use one of the 350W or 400W power supply I stripped from my previous PC's. I'm thinking of hooking it to an HDMI or VGA projector eventually though (Haven't bought it yet) Can I get away with one of these and play a game like World of Warcraft? or do I need to order something like the

A:New PC build - won't power on with EATX12v plugged in, no video without it


Correction to my original post: The video card fan is spinning and receiving power apparently. The big issue here is that the PC will not power on when the EATX12v is plugged in. If I'm not mistaken, that powers the CPU, does it not? Which would explain why there is no video when I turn the PC on without the EATX12v plugged in.

Is the mobo damaged? I just can't figure any other reason that the PC won't power on with the EATX12v plugged in and will power on without it plugged in.

I recently built a new PC.
I had issues powering it on, then I realised I forgot a 4 pin power connector in the corner. Next boot, everything booted up fine, to start. After 3 seconds it powers down, then powers back up and stays up. I think every thing is powered on, disk drive works forsure, the only issue is I get no picture. I am using a BFG 9600GT and used the dvi to vga adapter to connect to my old gateway 2000 vivitron monitor, though I will probably be getting a new monitor soon. I was thinking the problem could be either my video card, video card/monitor non-compatibility(or something to do with the dvi-vga connector) or maybe something else. Or could it be the power problems discussed before?

I am using an Asus P5QL-PRO mobo, 4GB(2X2GB) Gskill memory, 9600GT, E8400 processor and an Antec earthwatts(500 watt).

Hi all,

I've been doing some research on my new build and started looking into power phases. After reading some articles, it seems like the less power phases you have, the more susceptible your motherboard is to failing, especially if you're overclocking. Plus you also have to worry about components on your motherboard overheating such as the mosfets. Is all of this something I should be worried about?

The motherboard I want to get has 8+2 power phases (Asrock P67 Extreme4 Gen3). So if I plan on overclocking, should I step up to a 12+2 or 16+2 motherboard or will I be safe at 8+2?

Thanks in advance

A:New Sandy Bridge build - power phases

The ASrock P67 Extreme4 Gen3 is an excellent board. It overclocks impressively. People have managed to hit the 5 GHz mark at around 1.45V with a good aftermarket HSF.

More power phases do not guarantee better performance. Generally, more phases should make for smoother voltage output, but it is only one of several factors in the design of the CPU voltage regulator.

Well, I'd be real reluctant to fire that up with a 400W supply. When a supply goes, it frequently takes stuff with it.

I currently have this (and don't want them to collect any dust:
Asus Motherboard
Quad Processor
DDR Memory

Plus a couple hard drives, but absolutely nothing else. Since this is new to me, I'm asking:

1 - Is there a way the more experienced users would suggest going about a new case and how to know the appropriate power supply to buy.

2 - I bought the MB used from, and it didn't come with any wires/connectors. Can you tell me what I'd need to fully be ready when I have all the components?


A:New build case & power supply recommendations

I havnt done this in a while but here it goes.....

If you dont have the propor heatsink/fan combo you will need one of those for your processor.

For your needs just get a quality 500w PSU by Antec, Silverstone, Thermaltake ect ect. No $20 bargain buys. If you plan on putting in some super fancy graphics card, take the minumum requirments for that card off the box and add 100 watts.

Wires you will need are just your SATA cables.

The PSU should come with all you need to connect it to your motherboard.

I wanted to change my power and sleep settings for my display.

At first it didn't seem to work. Working through it methodically however, I found there are FOUR places that can be set for the same thing!

(1) Win10 Start/Settings/Display/Power&Sleep. I set it to never

(2) Below that in Additional Power Settings I was taken to the Control Panel. Checking the Preferred Plan settings the screen setting didn't reflect the change above.

(3) From the CP is another option: 'when to turn off display'

(4) Finally there are the "advanced power settings".

This is ridiculous. Surely all I need set is the initial (1) Settings? And this doesn't even include setting the Screen Saver which seems to be over-ridden by the other settings!

Obviously Microsoft have got their knickers in a bit of twist with some settings undertaken in Settings and others still in CP.

Hey everyone!semi new build(upgraded mobo), after installing everything, the pc will not post, I am not getting any power to the keyboard/mouse and the psu fan as well as other fans seem to be running kind of sluggish. Previously I had an issue where the hdd light would stay constant however that was solved with reseating the cpu a few times and resetting the cmos.specs are found here:, previous motherboard fried after plugging in earphones to front header. Could the psu have gone as well? Tested the new mobo today with known working ram and graphics card to no avail, so I have ruled those out.

Nickdangelo6, This is not a direct answer to your problem with you new build. Instead, I am going to talk about how to approach your vendor and ask for help with doing return on an item the did not work ever.Just tell the vendor that you have worked with personal computers parts before and you have friends that advice you. Tell them you were very careful when putting things together and used only compatible things.Do not mention anything that might even suggest you did anything wrong. Because you did not do anything wrong.Be polite and talk in a manner that shows you are confident and want the vendor to arrange for a way to replace the bad board.I do hope that will help you.,155953.0.html

I have an HP Pavilion 8562 I just bought off someone. It came without the HD, but with all the other original componants. When I hit the power button nothing happens, the light might flash, but the power supply does not start up. When I got it the big 8-pin thing was oput of the mobo, but I plugged it back in. It will not scan thdrives, or go to bios, or even make any noise or bring anything up on the screen. Assuming it is not dead, any suggestions? This is why I hate manufatured computers.

A:Doesn't Power Up

Can you move the suspect power supply to another box and test ? Can you move a good PSU to the failed box and test ? The PSU is the first component I would prove/disprove. (It would be better to test the suspect one on another, working box, as the failed box could have multiple problems which a good PSU might not fix and the results, therefore, could be misleading.)

also, have 2 processors and it doesn't work with either
the motherboard was sent back to the supplier to check for faults but it works fine apparently.

GeForce6600GT AGP = Bullshi*

Hi, I'm having a little trouble with my GeForce 6600gt (club3d) agp videocard.

I first plugged it in, beeps. I noticed my Power Supply didn't have enough output for the card (put my Radeon 9600 back in, ordered new one)

Well, later I received a new Sweex 400W power supply.

The GeForce worked fine, until it complained about not getting enough power.


I unplugged my floppy disk drive, it didn't complain about it on Windows startup, but later, after playing some games it started to complain *again*.

Is this a trouble within the card or do I just need to get a new power supply (again)?

A:GeForce6600GT AGP - Doesn't get enough power

it could be a defective card or it could be the power supply yuo bought is substandard. all PSU's are not equal. many of them deliver less that HALF of what their ratings say once they have warmed up. that is why it is best to buy a good brand name PSU, like antec, Vantec, etc.

A:Satellite Pro M60-164 doesn't power up at all


It seams that this has nothing to do with power mains but with an internal hardware problem on the mobo.
I think you should firstly check the both memory modules inside the notebook.
If the notebook would not power up even using new modules, then other parts like CPU or motherboard should be checked.

Sorry but this is everything what I could suggest you.

Hi CS,
did you clear the CMOS by removing, and moving a jumper pin?....if you did make sure that the metal insert (the part that connects the pins) in the jumper didn't fall out or come out of the plastic casing and stay on the second set of pins when you reset the CMOS.

A:HP laptop doesn't power up

Some laptops won't power up if the battery is not working, but I doubt that's the issue in your case. So far I've only seen that on Medion laptops, and I own a HP myself - pretty sure it should work without a battery.

That is indeed a rather intriguing issue. Seems like you're stuck in a difficult position.
I would normally suspect some kind of hardware fault such as motherboard failure. It could be something much simpler such as faulty power jack, which I doubt since the little light comes on.

Here are my suggestions:

1. Try a different charger, was yours ever getting very hot?

2. Remove the battery AND the CMOS battery and do a hard reset, then plug the charger in (without CMOS or the laptop's battery) THIS WILL ERASE YOUR BIOS SETTINGS. Doing so on my laptop would cause it to power up without having to press the power button.

I have read through the forum and most of people's problem was with the PSU or MB. Any idea what could be the problem in my case? Or anywhere I can go to have someone troubleshoot my PC for me?

Hi New member - please be gentle if I haven't followed the correct procedures Okay I rebuilt my PC completely following a mobo failure retaining the hard drives I was really impressed Win Ult x booted straight into the desktop I removed old mobo drivers added new ones errors state) Build BSOD Machine 9F power randomly New (driver Had a few glitched with the USB ports which I think I fixed by deleting and reintalling new drivers I have had some BSODs - one after the other just New Build Machine BSOD 9F (driver power state) errors randomly now and at least earlier one while the machine was unattended In each case it was a BCCode f and I got the error message driver power state failure Now I have the crashdrump logs I think it has zipped but I know the most recent one related to the crash I just saw is called - On a whim in the interim I have also just now uninstalled the Asus AI Suite that came with the mobo Asus z pro gamer as I know it has an energy management module and even though I have tried to disable that anyway I thought might be a cause for error I would be most grateful for help in tracking down the cause of this error and advice on fixing it please Thanks

Hi guys I ve had this problem with my PC now for the last few weeks When I power up my computer it doesn t switch on immediately and didn t come on until around mins later This mins then doesn't power up immediately Computer became mins When the computer did power on however everythign was fine and I could access all my files etc properly I suspected that it may be the PSU or MB I opened it up and first took the MB s battery out and then put it back in again after mins This didn t do anything At this point I had brought the computer downstairs Then I decided to make sure the whole tower was free of dust etc and then try it All of a sudden it started to work correctly i e I could switch it off and then when I switch it on again it would come on right away I Computer doesn't power up immediately took it upstairs again and the same problem started again During Computer doesn't power up immediately all this however the motherboards green power light is always on and I can t see any warning lights or obvious areas of damage to it My dad then took the battery of the MB out again and put it back in again and then it started coming on immediately again However I went to try it again and guess what it s not powering up at all now again What do you think may be the cause of this Is a new PSU in order When I manage to get into BIOS In the Hardware Monitor section the voltages are all indicated as being correct i e where it says it should be it is and where it says it is etc The CPU s temp is around C and the motherboards is C I havent installed any new software etc and dont think I have any viruses as I hardly have anything on my computer as it is But I installed a Netgear USB Wireless device which kept hanging forcing me to keep on having to switch my computer off from the power button as opposed to shutting it down through windows I have since uninstalled this Your ideas suggestions will be much appreciated Thanks Sukhraj Intel P GHz Asus P S X MB MB RAM Windows XP IDE Gb HDD nbsp

A:Computer doesn't power up immediately

There is a jumper you can reset so you don't have to remove the battery for 5 minutes every time.

I don't know what the problem would be, but it is easier to replace or try another PSU than it is to replace the motherboard.
