A few months ago I built a system for a friend of mine consisting of the folowing:

X2 3800
Zalman CNPS7000B-ALCU LED CPU Cooler
DFI Lanparty UT nF4 ULTRA-SLI (sorry, not sure which bios)
BFG GeForce 7900 GT PCI Express 256MB
WD 250Gb HDD (x2)
Corsair TWINX2048-3200C2 2GB Kit DDR400
Silverstone Strider 600w PS
XP Pro

I had the system running stable @ 2.4 GHz (memory on a 5/4 divider, if I remeber correctly) for a week before I delivered it to him. By stable I mean dual prime overnight, memtest, and hours of COD2 without crashing. Now he has had it for a few months and he is reporting that randomly it will completely shutdown. He primarily uses it to play WoW and so far that is the only time it has crashed. It has not crashed during any other activity but he really doesn't use it for much else. It will usually crash 5 minutes into game play and after a restart it will be stable for the rest of the day. Ocassionally it will crash a few hours into game play. When the behavior first started it would BSOD. Now it just turns off with no warning. After restart it works fine. When it shuts down the standby LED on the MB remains lit but the DRAM power LED does not. I have updated the Graphics drivers to the latest 90 series beta drivers. That did not affect the problem.

To me this sounds like a graphics driver problem. But I am not sure that it is. I thought it may be in the power supply (since the whole system abruptly stops), or it may be in the power management settings in Windows, or in the power management settings in the BIOS. I don't think it is a heat issue, because the system doesn't get very hot and it works well after the restart.

Any solutions or trouble shooting ideas would be appreciated.

apart from saying i dont think thinks its a grfx driver problem i have no clue..

the system is unstable for some reason.. just try slowing things down one by one and hope u find the problem.. the works fine after a restart is odd.. or do u just mean till it bombs the next time..

I mean that it only occurs once during a session. it will crash and then after a restart will run for hours with no problem.

there have been news about preoverclocked nvidia cards from XFX and BFG that had higher fail rates then standart spec cards, see if the card is preoverclocked and if it is, try to lower it to standart 7900GT specs

the 7900gt's have problems after a while from being pre-oced, i think its the cooling not being up to par for the prolonged amounts of time at the oc
