My friend's PC is ... dead AGAIN?

post #1 of 10
Thread Starter 
Hello!
My friend has a weird problem with his PC. He used to own intel configuration DFI Lanparty P35 motherboard and an intel dual core e6300 . He used to clock it with no problems to , idk something from 2,6 to 3,3 or something , irrelevant. However , he sometimes (most of the times) when he rebooted the PC got no video input on his screen. Then he had to remove the CMOS battery and hope to god that it boots again... Few days ago the battery trick didn't work anymore and the screen stayed black with "No Video Input" on it... So he bought a new mobo and CPU thinking it's the mobo that's causing all this (i tested his gfx card in my pc and it worked).
He bought this AMD set : ASRock 790 Extreme4 with an Athlon II X3 445 which we unlocked to X4 on stock speed and voltage , stable!
After 5-6 reboots it worked great , installed new windows etc , and then same error again "No Video Input"
I really don't know what's wrong anymore... Maybe PSU?? HD drive? GFX?? That's the only components he didn't change..

Power Supply.

As above check the PSU with a known good one, thumb.gif

You say you have already checked the GPU in your machine, so chances are, that is good.

New MB and CPU, so chances are very slim there as well.

If a HDD fails or is failing you will still get video display during POST. But Windows will not boot, or will with problems.

If it is ram you should get an error during POST.

So I would be more then suspicious about the PSU.

I could have been a loose connection - just a plug not connected right. Or the PSU is being overloaded, tripping out, and resetting when you have it out the machine, or disconnected from power for a few minutes. I think it's all pointing to a PSU problem. smile.gif

sounds like the PSU to me as well. as they get older the capacitors in them start to leak or dry out, in turn they put out less power. now he has added a little to the power draw. some times it might be enough to boot, some times it might not be. only other thing i would say is check and make sure everything powers up when you get the no video problem, if so then do a easy cheap check and replace the cable from the vid card to the monitor. i have had that happen as well.

its also about quality a crap psu will die before a decent psu will
post #9 of 10
also it depends on a lot of factors. quality of parts, venting of heat, power load that was ran on it. how close to the limit was it ran. there are just so many factors that can make a psu stop working properly, or trip the protection. it could even be it is loaded with dust and something shorted out from it if it got moist.

It may boot with a bad PSU - but as you find, it dies as it gets loaded up with programs, all which add to the draw in power. Plus. if it has crashed due to power problems, then the integrity of the windows install comes into question. I'd bet, if you ran chkdsk or SFC /scannow (system file checker), you would find errors in the install. And it can get progressively worse each time it crashes/reboots. You'd have to do a fresh install, on a good PSU.
