Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)

MB: MSI P35 Neo2 FIR

PSU: Seasonic M12II 500W

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

My PC suddenly shut off and wouldn't turn on, but the mouse and motherboard lights were still on. A tech took my PC and ran some tests. I assumed that either my Power supply or my Motherboard was unfunctional but he called me back telling me that it was neither, and that the problem was coming from "a part" that gave power to the motherboard. The replacement of this part would cost $80.

Am I getting ripped off? What part could possibly cost $80 and isn't the Power supply?

OK I ll try to get it right I have an Intel Ghz Duo Core on an ASUS Motherboard Gig RAM and all about six years old running Windows Pro When I do a cold Power what? OS? or Motherboard? .... supply? bootup from the power OFF condition the PC freezes at the BIOS message and will sit there forever If instead I press DELETE on bootup it will boot right through to the BIOS settings page blue white screen whereupon I do the ESC and EXIT bit get Power supply? Motherboard? OS? .... or what? presented with quot Start Windows Normally quot and all is then OK If I do a reboot using the reset push button it will only proceed to the BIOS part where the HARD DISC is checked and again will sit there for ever Now to confuse it further if I turn the PC OFF and ON using the front deck push button it will do a normal reboot right through to starting Windows correctly Whilst the PC runs reasonably well thereafter it is quite common Power supply? Motherboard? OS? .... or what? for it to do a complete and total shutdown for no reason whatsoever or the keyboard or mouse to suddenly stop working On the back of the deck is yet another ON OFF switch and using this to reboot the PC results in a normal bootup So something stinks using the RESET Pb on the front of the deck or a normal cold bootup I replaced the Motherboard battery pushed and pulled all the wires - as you do - all to no avail It is far from a happy PC and I suspect either the power pack is playing up or the Motherboard is on the way out It is quite common to be tapping away quite happily when BANG the whole thing does a complete shutdown following a keystroke or adding a USB device such as a camera or such For no apparent reason on a bootup it will decide to reinstall a whole stack of drivers that have been working satisfactorily to date It may be the Windows software as after I took it to the local repair shop now defunct I keep getting messages that Windows is not the genuine version When I asked the Techie on this one he said thay had used one of quot their Windows discs quot to effect some repairs - yeh I have everything backed up so am very gtempted to format the whole wretched thing and try again I know the above explanation is a but hard to follow but hoping someone can see a glaring problem Is there any disgnostic software I can download to do a check on the hardware or is this a waste of time Thanks nbsp

A:Power supply? Motherboard? OS? .... or what?

Sure. Start by going into the bios and checking your temps and voltages; specifically the cpu temp, system temp, 12V, 5V, and 3.3V values. Post those here.

Next download and run memtest This runs from bootable media ie CD, floppy, etc. You need to make the bootable disk and restart with the disk in the drive [CD set as first boot device in the bios]

Test the hard drive with the drive maker's diagnostic. You download this from whomever made the drive ie WD, Seagate, etc. Most of the time you have a choice between a windows version and a dos or boot version; get the boot version. Again it runs from bootable media.

One other thought; have you cleaned the system at all? If not, open the case and give it a good cleaning with a can of air [available at any office store, computer store, even walmart]

My computer was working great.  I went out of town for a week and upon my return, it would not turn on.  The green light on the power supply was lit but that was as far as it went.  I purchased a mobo but this did not fix the problem.  I am not real computer literate but have experience.  Does this mean that the power supply is gone since no power seems to go beyond the light?  If not, can you tell me what to try?

Hi, I'm on a mission to patch together some kid's emachines T2682 P4 pc. I'm pretty sure the motherboard is toast, I managed to get it running once, began a defrag, then the screen went to "no signal" (I could hear it was still running) and on reboot, no beeps, no post, no signal. The fans run, so I think the power supply is ok. I removed the ram, still no beeps, no video signal. I'm set to order another board, but I read where in most cases the power supply is what causes the mboard failure. Should I get a power supply and try that first? Is there a way to just check the ps?

A:Power supply or Motherboard?????

I would replace the power supply at the same time as the mother board. I had a faulty supply that seemed to work, on an Emachine that was under warranty. It blew the motherboard and keyboard and a wirless adapter that was pluged into the usb port at the time. they replaced all the parts but the wireless adapter because that was my own part. They put in a used power supply and just after the warranty it went out again an took the motherboard with it again. I took out the harddrive and threw the rest in the garbage. No more emachines for me. It was cheap and used as a second computer for the grandkids so no loss.

A:Power Supply or Motherboard?

Hello there and welcome to Techspot!

I feel your pain. We've all been there. Not that sympathy makes things any better, but you have mine.

It is hard for us to tell what is wrong with your system without looking at it of course. But maybe we can help you confirm a few things.

You say you can see the green LED light is lit up on your motherboard. That's a good thing. When you push the power button, no fans are spinning at all? Not a good thing.

It could be any number of things, and the tests that need to be done involve removing parts to help troubleshoot. Do you feel comfortable doing these types of things?

Try unplugging and reconnect your power supply connections to the motherboard.

I would also test your computer case's power-on button. This is done by disconnecting the small 2pin cable from your case that goes to your motherboard, then using a screwdriver to quickly touch the two pins that that cable was connecting to. This will short the pins, and hopefully start your computer. If it does, then your power switch on your case needs replacing.

Other than that, I would try this test to see if you can get the power supply fans spinning:

If the fans on the PSU don't spin, then you have (another) dead power supply.

If the fans on the PSU do spin, then we have narrowed you down to either a dead motherboard or a dead CPU (probably motherboard)

I was replacing a fan in my case because it made a high pitched sound. I took it out to test it to make sure there wasnt too much pressure from the screws inside the case that were causing this noise. I unplugged one of the molex connectors from my gfx card to test it. It still made the sound so i plugged the molex back into the 2 molex to 6 pin connector and the computer shut off immediatly. Now when i hold down or just push the on button my led flashes and fans spin and stop repeatedly. Any Help would be just the best thing right now.

~Thank you


A:Motherboard or Power supply

NEVER unplug or plug in anything except maybe case fans inside a computer with it powered up! Pull out the video card and see if the computer powers on. If it powers on you have fried the video card. If the computer still doesn't power on, the power supply should be changed before you suspect the motherboard

Hey fellas. My mother in law had a power outage quite some time ago. When it happened her pc would not turn back on. Is there any way to check to see if the motherboard is still good? I would like to get it working as a secondary computer. Also, how can I tell what kind of power supply is required for that motherboard? Because I have tried a couple power supplies, and one was from a OLD 166mhz pc, while ther other was from a 866mhz, but it seems like the ends or where it plugs into the motherboard are different in shape. Any suggestions? This is a HP 900mhz pc, it would be nice for web browsing and other task. Thanks for any help!

I was looking through motherboards and noticed that this one has an 8-PIN power connector.

What am I missing? How do you connect a 4-PIN PSU to an 8-PIN board?

A:Either Power Supply Or Motherboard went out

Maxtors fail way too frequently. Next choice is the power supply. Watch from the back with a strong light when the <ON> button is pressed. Does the fan blade turn four revolutions or less. That is a bad power supply.
There is no relationship, really, between heat and a BSOD. It can just as easily shut down as give you a BSOD.
I'm betting it is power supply, memory module, or Maxtor failure.

Hello, I need your advice please.

I have a system based on a Epox 8KHA+ with the latest BIOS. 512MB RAM, AMD XP2000+ not overclocked, running at 56 degC., Windows XP fully updated.

The problem is the system keeps turning itself off. After about an hour of running, it suddenly dies as if the power plug had been removed. If I try to restart using the power switch nothing happens. If I then unplug the power lead and replace it, it then starts up OK.

Any ideas please?

My pc won't properly boot up (i.e. all the fans turn, but there's no video input), so I have troubleshooted all parts. Eventually I put my PSU in another computer, to find that that one didn't boot at all. I concluded the PSU had to be broken.

As a last test I used a multimeter to manually test the voltages of the 24-pin connector and found that they were all next-to perfect.

Does that indicate that the PSU is healthy, and my motherboard must be dead?

No. It just means that under essentially no load the PSU is delivering the proper voltages. The voltages supplied under load may dip well below what they are supposed to be.

I am working with a friends Emachine T2042 2ghz Celeron. She told me that the machine wouldn't turn on - no lights, POST, etc. I replaced the PSU and am having some problems. Once I connect everything, only the PSU fan and the fan cooling the CPU are operative. No HD lights, POST, etc.

I've checked the 20 pin connection to the MOBO. It seems to be seated correctly. Any other ideas?


A:Power Supply - Motherboard problems

Hate to sound brash, but you're yet another person with a bad emachine. The bad news is emachines are notorious for horrible quality computers. This problem is posted ALL the time. The components and construction in emachines are of the cheapest quality. Their PSUs often blow out - often taking the motherboard along with it. If the computer is still under warranty, send it in. If not, test the PSU. You might be able to replace the PSU - however don't be surprised if the motherboard is also fried. If not- you're lucky. If it is toast , you might be able to salvage components and/or data by building another computer yourself.
You can buy a PSU tester for $12 at circuit city.

To all others: AVOID emachines period!

Hey guys,

My motherboard has recently blown and I've had to replace it. My only issue is that it has a different internal power source to my former motherboard and I'm not sure if I can utilise my old power supply with it. I've included pictures of the motherboard connection (the blue one) and the power supply connection. Power supply connection is for a larger connection but it works perfectly with the motherboard, except it is inserted into 4 slots rather than 8.

Is this safe? It seems to be working fine.

My question is , when I looked it up on, there were two....there is a ASUS A7n8x-x going for @ 74.99 and also a ASUS deluxe for about 118.99 , they both have nvidia nforce2 utra 400 + Mcp, is there a big difference between the two as far as perfomance? I also saw a ASUS A7v8x-x with a VIA chipset ( my comp ran a VIA before) and I just wanted to make sure that I can run a nvidia chipset.
Also.... I looked into my power supply and it's a 250 W max. I am not sure what wattage max I can ,or should go to . Any help would be great. thanx

I recently bought a new computer from Dell and a new graphics card from newegg The computer is a Dell Inspiron and my graphics card Supply Motherboard and Issue Power is a Nvidia Geforce GT The graphics card requires a minimum of a watt PSU which unfortunately Dell only gave me a watt PSU So I replaced the watt PSU with a watt PSU that I purchased from a store near my place but when my computer is shut off the motherboard would make static noises The noises sound like a cross between clicking static that appear around minutes after my computer has been shut down and start to fade away after an hour The noises would only go away if I switched off the power on my PSU I replaced the new PSU with my old PSU and the static noises went away The power supply that I purchased was this http www coolermaster-usa com product php product id I called Dell about my problem and they said that the motherboard could not handle a power supply of more than watts I bought the computer and graphics card online so it would be a real pain to return and I m not really fond of replacing my motherboard I was wondering how I would be able to get rid of the static noise nbsp

A:Motherboard and Power Supply Issue

Dell lied to you, the motherboard has no idea on the wattage of the power supply, it simply draws as much as it needs. That said Dell's are cheap systems.

The power supply you got isn't of the best quality, and it may also be faulty. Return it for a higher quality brand and see if that resolves your problem.

I made a thread this summer regarding problems charging my iPod. I had been assuming it was an issue with my motherboard, but recently began thinking that it could very well be my power supply. I was just wondering which is more likely, and if there's a simple test I could do. I'd easily be able to get my hands on a DMM.

This is the thread from this summer:

A:Motherboard or power supply problem?

Only thing I can think of is to test the PSU in a different computer - or better still, put a known working one in your PC. Seems strange that the iPod not charging is the only symptom of either however.

I currently have a dell E310 dimension w/ a 230 w power supply
i want to upgrade to a ATI Readon 9250 PCI video card which requires more power
I have a Thermaltake Purepower 420w power supply which has a 20 pin connector--the motherboard has a 24 pin socket. there is also a 4 pin plug from the power supply . will the computer work with the 20 pin connector or do i need all 24 connections? --is the 4 pin connector supposed to make up for the extra connections?

A:20 pin power supply to dell 24 pin motherboard

Should work fine with the 20 pin, but there is another spot on your board for the other 4pin

the power supply should have 2 cables, the 20pin(or 24pin) and another cable with 4pin, both of those go in differnet spots,

and from what i know it shouldnt be a problem with the 20pin going in the 24pin.

I have a power supply of ATX 12V V1.3 and my motherboard has a label says "24-pin ATX V2.2 Power Supply." Are these two components capable? Will there be any kind of problems that might occur such as pc shuts off itself and automatically restarts?

A:incapable power supply with the motherboard


Are you sure you don't mean "compatible"? If the PSU has a 24 pin plug for the main connection to the board, then it is. Earlier PSUs have a 20 pin plug for the mother board. some PSUs have something called a "20 plus 4 connector" which will work for both new and old motherboards. Since there is only 1 plug (the main board connector) coming out of the PSU with anywhere near that many pins, simply count 'em. 2 rows of 10, no worky, 2 rows of 12 in like Flynn.

A:Does the CPU's W have to match the power supply or the motherboard?

When looking at a new CPU's compatibility to a system, check whether:-

1) Your CPU supports the socket that your motherboad has.

2) Your motherboard's BIOS supports your CPU, if it doesn't, check the manufacturer's website for updates that'll allow support.

3) Your current cooling setup (Heat sink and fan) supports the new CPU.

4) Your Power Supply Unit (PSU) is powerful enough to handle the CPU. This is what you meant in your above.

Fill up your current system specs and tell us which CPU it is you intend to upgrade to so that we can advise you further.

It was in perfect working order previously, with all cables and equipment functioning, and the BIOS and everything was up to date.

Alright, well I'm looking at purchasing this motherboard here:

If you'll look at a couple of the reviews, they mention this:

I neglected to get a 20+4 pin power supply for I dont know what reason, but once I had that everything worked. If you have a GPU which 256MB dedicated RAM or above it is reccomended that you get at least 14 amps on the 12 volt rail.Click to expand...

I have a 256MB GPU. My question is, what does that guy mean by the 14 amps/12 volts/20+4 pin power supply, and what do I need to get one? The case I'm looking at buying is this: Computer Cases

Does that include enough power, or should I be looking at another power supply in addition? Thanks in advance for the help.

A:Motherboard Power Supply Question

I'd recommend taking out the power supply that comes with that case and getting yourself a reliable one. Powmax are not really PSU makers, they are case makers (who include PSUs with their cases). In other words their PSUs are made with very cheap parts. You do not want a cheap psu. Read through this forum and you will see many people with really hard to diagnose problems that most of the time are the result of going cheap on the PSU.

To answer your questions briefly:

PSUs put out different types of power, as different parts on you computer like different flavors of power. There is 12v power for some parts, 5v power for others and 3.3v for the rest. A cheap PSU is not very good at making these different types of power, specifically the 12 type. A good PSU should be putting out at least 24amps as a minimum.

And the other question, your motherboard uses a 20pin connection from the PSU. Most new PSUs are a 24pin connection, but a lot of them have adapters that come with them, or better yet, the 24pin connector actually allows you to "snap" off 4 of the pins to change it to a 20pin connector.

I'd recommend getting a PSU from a company like enermax, fortron or Antec. Have a look at this thread for some great info:

I have tried it every different combination that I possibly can. The led on the mb is on. Any suggestions? I can't even get it to do anything. This computer worked until I took out the old parts and replaced them wiht new. Is it possible the MB is bad?

A:problem with power supply and motherboard

Yes, the board could be bad; but, more testing is in line before deciding that.

Are you certain you have the power-on switch connected to the proper pins on the board? Thoroughly checking this is a must. Study it carefully.

Is it possible you have the CMOS-clear jumper set to 'clear'? I have bought boards that had this setting out of the box. I never could figure why they would do that; but, they did.

Are you certain the processor is fully seated into its socket? And, are you certain there are no bent pins?

If you have checked all of the above and found nothing amiss, disconnect everything from the board and remove all add-in cards and see if it will power up.

The only response is a red light on the mobo.

Both p/s are atx that plugs into 12V socket.

I find the following on the mobo for mfr: ASUS ASB100/SIS963/ATA 133. Not sure where the product ID is on this mobo so wasn't sure what ps would be compatible.

I bought a Chaintech CT-7AJA2/AJA2E Motherboard and an Athlon 1.2 gig proccesor. I hooked everything up, then the power supply blew. I believe that I hooked the power button cord reverse polarity, not sure.

On intial start up, looked like it was going to run just fine. I am not sure what I did, but I need help badly.

Got a new power supply, made sure the polarity was correct and plugged it in. Nothing happened, no led light-up or sounds, nothing, Heck the power supply didn't even blow up this time.
p.s. By blow up, I mean burnt out. Smoking and such.

A:Replaced motherboard and power supply now I freeze.

start by checking all the jumper settings.If there ok or resetting them doesn't work try flashing the bios if you can. make sure all cards,connectors tightly inserted,If problems persist remove devices one at a time.if it works when you remove a device then that device is the problem and needs to be replaced.If any of these are shorted they could cause freezeing.

I'm currently running a machine with an 8-core processor and a 550W Power Supply.

The machine won't run on all 8 cores. It gets to the "Windows Startup" screen and shuts down. It's not running hot as far as I can tell, and if I manually shut down a pair of cores in the BIOS it runs just fine. I am currently running it on 6 cores, but would like to run it on all 8.

Is my Power Supply not powerful enough, or do you think it's another problem?

My System:
Processor: AMD FX 8120 (8-core), 3.1GHz Socket AM3+
Motherboard: ASUS M5A88-V EVO
Power Supply: Logisys 550W ATX12V
Video Card: *Currently using onboard*

A:What size power supply do I need for my CPU/motherboard combo?

Your 550W PSU should run that system just fine. Is your BIOS up to date?

Hi we are building a pc and have the following problem.
Internal LED from power supply stays on - so good, however pc was running now wont turn on. The 24 pin connector from the psu to the motherboard when partly pushed in makes the pc flash on and off - when fully in pc wont turn on at all, led stays on. Power supply is good as we tested it.
Any help would be greatly appreciated.

A:Internal power supply problem to motherboard

Is the motherboard in the case? Are you sure that the motherboard is standing well off from the metal case? If not you may have caused some damage by pushing the connector hard and shorted the motherboard onto the chassis.
How have you tested the power supply? No load tests may not show up a problem.

A:Need input from power supply/motherboard guru ..

First, I believe that Intel chipset 850 is the immediate precursor to the 8X5 chipsets, with Northwood P-4 CPUs, (845,865, ya da ya da yadda). However, I've seen references to an older socket, (423), as well as the socket 478, with 850 boards.

(Edit; I just researched this. It seems there is an adapter to allow the use of socket 478 CPUs in the 850 boards, which are socket 423).

PSU failure is very often accompanied by a failure to wake up from standby. The seem to run OK, but when you shut them down, the seem to "die of natural causes".

The, "you gotta pull the plug, and plug it back in before it will start" behaviour shows a failure in the "soft off" circuit.

I think there's an amount of +5 volt current required on standby. This is to keep USB "alive".

Before I would plug the 6 pin "aux" connector into anything, I would check the voltages. The red should be =5 volts, and the 2 orange wires MUST be 12 volts. The 3 blacks are grounds, keyed to the hot wires.

In a rhetorical sense, if the 6 pin block would plug in correctly, with the two orange wires to the 4 pin CPU block, (and they were in fact +12 volts), it would probably be fine.(Don't forget proper orientation, the positive terminals should be marked on the board).

In the real world sense, I'd definitely spring for another PSU, and not experiment with it.

I don't think the +12 supply directly to the CPU back then, was as critical as it is today. Once upon a time, CPUs had a much lower current requirement. (Which is why they also ran cooler).

All of that said, I seriously doubt that your old PSU was fine.

Currently, I turn my computer on, and nothing happens, except green light on mother board and yellow light on computer "On" switch. I started testing power supply. That obviously works. I disconected everything from power supply and started to reconnect everything one by one.
Everthing seemed to allow the test switch on power box to power everything except when i came to connecting the 2x2 auxiliary atx 12v power connector (P9), into the mother board. It quickly shorts everything out, and i'm back to square 1 with just having the yellow "on" switch and green light on mother board, and fans shut off again.
Whats the problem?

Any help would be greatly appreciate.d...


A:Connecting 2x2 connector from power supply into motherboard shorts everything out?

If you don't own a power supply tester take your tower to a local shop and have them test the power supply. Even if the power supply tests good, have them "jump" a known good power supply to the board and see if the problem continues.

I have people bring towers in quite often for testing. It takes 20-30 minutes and the cost should be minimal perhaps $25-$30. You need to find out if your problem is with the power supply or the motherboard.

Customer has brought me a Sony Vaio PCV-C11L and an ATX power supply that he wants installed to replace 'blown' PS.

Motherboard is ASUS P4SD-VL and the existing PS has additional power plug (P2 3-pin) that plugs into port immediately adjacent to main power (P1).
While the physical dimensions will offer a problem to installation...... I think that can be overcome. My greatest concern is just what the P2 is for, since the replacement PS doesn't have that plug . Have not been able to locate a 'map' of this motherboard -- Sony doesn't have any info.....

Hello, I the power supply light of my Media Center m1050y is blinking and the PC does not turn on at all. So I tried the troubleshooting sequence posted here in the HP Support site, and after unplugging all the cables and replugging them one by one, it turns out that the light blinks only when the PS is connected to the mother board (the connection is a white, wide plug with about 12 pins - pardon my ignorance on the actual name). I looked on the internet about trying to narrow the cause on the motherboard and I unplugged the front USB ports, the fan, and other "solutions" without any luck. Does this mean the motherboard is fried and either I need to replace the motherboard or look for another PC? Thanks!

For a little while, I was periodically getting the blue screen of death... more frequently lately. When I checked the Event viewer in Vista it had an error each time it happened that said something about Power Management kernel error and Processor 0. Also I sometimes heard beeps before the blue screens would happen that sounded like it could be coming from the power supply, but it was hard to tell. Now the computer just freezes at the motherboard splash screen and will not boot (can't even get into BIOS). Could this be caused by a bad power supply?

A:PC freezes at motherboard splash screen, could it be power supply?

Not likely. It is more likely the hard drive is failing... or you have a problem elsewhere.

Usually the power supply will either work or quit all together.

A:Power supply requirement for ECS KM400-M2 motherboard: 350kw or 400 kw?

Kilowatt? Thats a PSU with balls! 400-500 watt should be fine. Has anyone told NASA? All this time they've tried to spend millions on glorified supplys fort they're system,s and all they had to do was throw a few hundred bucks towards the lovely people at whoever makes those PSU's

Is the version of Windows XP 64-bit by any chance? If so, that could explain the intermittent behavior...

You might want to go with a 400w power supply from a trusted manufacturer

Hi all.

I recently picked up a computer, here are the specs:

Pentium 4 1.7GHz CPU
Asus P4B-MX motherboard
20GB hard drive
10GB secondary hard drive
32MB AGP video card (don't remember the brand, but it is not an onboard card)
400W power supply
Windows XP Pro SP2

It all works properly as is. Now, I tried to replace the video card with a LeadTek WinFast A280LE 128MB card (I cannot tell whether it is nVidia or ATi). This is where the problem begins. It starts up properly about 10% of the time. The other 90%, at the POST for the BIOS, it does one long beep, then 3 short beeps before continuing on to Windows with nothing appearing on the screen. Interestingly enough, Windows still works.

Offhand, I have discounted the problem being drivers (at the very least it should go through the POST) and device conflicts (ditto). Can anybody help?

During a recent storm lightning struck very close to my house and we lost power immediately after the lightning strike Once power was restored my HP Pavilion a would not re-start The computer and all the peripherals were protected I thought by two surge protectors On closer inspection I found that the green LED on the power supply was blinking I disconnected all the connections coming from the power supply and when I did the green light went from blinking to steady on I re-connected the leads one by one and the light stayed on until I connected the pin connection to the motherboard As soon as I connected the pin lead to the motherboard the solid green LED went back to flashing I assume from the diagnostics that something on the motherboard was fried by the lightning is Connector Power Pin Starts 20 to Supply Blinking When LED Attached Motherboard on I know how to replace a power supply but have never dealt with motherboard issues so not sure how to proceed The computer is only months old and LED on Power Supply Starts Blinking When 20 Pin Connector is Attached to Motherboard I would like to save it but don t know what I might be looking as far as expense and time involved to repair Any help you can provide would be greatly appreciated nbsp

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A

A:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!
Maybe you can exchange it?

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

A:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

Yesterday in my house,electric fuse was switched to turn on cooker in my kitchen. During this power delivery was stopped for 4-5 second only.
When power back on then pc automatically turns on and just before bios show me :"?Power supply surges detected during the previous power on ASUS anti-surge was triggered to protect system from unstable supply unit.
Press F1 to continue.? And then pc booted fine to Windows.

Is this normal ? Did it damage something? Why i get that message is this normal?
