I moved my PC, two monitors, keyboard, speakers etc...almost two feet to the left, onto my new desk. Everything functioned fine before I decided to organize today. When I powered on my PC to browse the forums among other things, everything was fine...until about 60 seconds later. The Monitors Shut off. The System Still Hummed, and it was almost like it went into hibernation.

I thought it was because of the dual Monitors hooked into my ATI all in wonder card. I unplugged the VGA 2 monitor, The Main Monitor still shut off after 60 seconds. I switched monitors, even pulled out an old ****ty CRT to test it, and it still shut that one off. monitors are not the problem.

I booted from a linux CD thinking that maybe it was Windows XP giving a bogus command to hibernate or something...nope, still at about sixty seconds or a little bit after, it shut down.

I pulled my video card and hooked the monitor into the on board video. Still Did it.

I thought that maybe all of the dust had shifted in the case, and I needed to clean it, maybe it was overheating/shorting out etc...so I just spent the last hour breaking down, cleaning and reassembling my PC.

I just booted it up, and the monitor still shuts off after the same amount of time. Just out of curiosity I went into the BIOS setup to see if there was a way to disable the on board video controller, but I couldn't get very far in sixty seconds. And there wasn't any options like that as far as I can tell.

What the hell could it be? I'm thinking that it has to be a motherboard problem. If I eliminated the Monitors, Video Card, and OS as the problem, it has to be the mother board, doesn't it? But why would it act up after I shift it two feet to the left? I can't think of any other outside factors that it could be.

Here's my system specs:

-ECS Motherboard P4M800PRO-M V1.0A
-Intel P4 2.66 Ghz processor
-4gb RAM DDR2
-ATI All in wonder video card

If there's any kind of troubleshooting I can do that I'm missing please let me know! I'm just trying to find a way to avoid buying a new motherboard. Please help if you can...

edit: I'm writing this from my laptop if you're curious.

Possibly an overheating issue. Boot into the BIOS and check your temperatures and voltages.

You've eliminated enough possible problems that I can suggest trying a different power supply.

Power supplies are still very much older hardware devices, and yes moving/bumping your computer can upset them.

The fact that the build has an ECS board, tells me it probably wasn't matched up to a very sturdy power supply.

The Power supply is a Siverstone SST-ST50EF, I sacrificed on the mother board quality To get a cool case and power supply, I really didn't think that was the problem, but since nothing is for sure I did check anyways, and got the problem continued. So the only thing left was indeed the motherboard. Yes, my low quality Motherboard was the problem.

So today I bought myself Gigabyte P35C-DS3R and the problem was fixed. But now I have to (begrudgingly) eventually upgrade to SATA hard drives. But thanks for all your help. Now I have new issues with getting the dual monitor function to work. Thanks for your suggestions.

That wasn't a bad plan per se, but there are cheaper power supplies that you can trust just as much as the Silverstone that would have left you with enough budget to buy a better motherboard.

I'm glad you got it sorted out though.

Good luck with the Gigabyte. I love their boards.
