My friend is having a problem

[Cake Faice]

Every time he plays any game, at random, usually within 20-40 minutes, the game freezes, the sound loops every millisecond, and his whole computer locks up, thus forcing manual restart.

And I built his computer for him. We've tried switching out power supplies, changing memory slot positions, graphics cards, hard drives, using multiple -dxlevel tricks and the works of it. Yet nothing I can do will solve that issue. I'm starting to feel bad that he spent $900 by the parts I told him to get at our local electronics shop. Here's what we got:

550W PSU
ASUS Radeon HD 5770
Antec case
ASUS P8 P67 EVO motherboard
6GB of RAM
1TB Samsung hard drive
Windows 7 home edition

And yet his computer is fine without playing games, but once started, it starts the locking up stuff. Any suggestions?

This happened to me when my PCI-E 16x got burnt.

Oh damn, haven't thought of that one. Usually the games run fine, Gmod goes up to 300fps, Source games around the same rate.

Mine would work perfectly. Fucking fine beautifully. But it'd sometimes get so goddamned fucked up I'd smash my CRT monitor. That LG Studioworks 710e was a beast.

You could try running it WITHOUT the GPU.

If that way, the Pc runs perfectly, then it's definitely the slot.

Alright, I'll tell him to try that suggestion. And if it turns out to be the case, hopefully the PC shop will exchange his mobo for the same exact thing.

Yeah, that's what I did with me old PC. Had an ASRock that cost around 40 dollars, which, together with my GeForce 9500GT is now my family's PC.

The mobo I bought him costs around $120. It would severely suck the heads if we had to buy a new one.

Well, it happened to me after the warranty was over. Also, as far as I know, they should replace it. It's fucking impossible to fry the slot and ONLY the slot.

*ONLY the slot in purpose.

Well we've tried the onboard thing, no dice. Still froze. So I guess I'll have to take the whole motherboard back to the store to exchange it. Anyone else got any last minute ideas?
