Computer Locking Up

Similar to this guy's thread but I'm not getting a BSOD so I figured I'd start another thread.

I can pass Prime95 for a long time but if I play a game (namely BFBC2) for around 30 minutes sometimes less the system will just completely lock up and freeze leaving everything on the screen but making the terrible buzzing sound through the speakers like it's looping the last half second of audio over and over and over and over.

Windows event log shows Kernel Power & Event ID 41

I've got a 4-rail PSU that's 2 years old and I'm suspect that it may be the culprit. Any ideas? I've reset my bios to default everything. Just got a Noctua cooler so I know it's not running hot and my card isn't too hot so I'm not sure what the issue is.

if its around the same time usually related to heat or voltage
if the game run well and has no strange on that like slowing i guess not the software
have you check the heat of your vga, update your driver and does it happen on other game?

Haven't really played any other games like it to find out. It hasn't always done it. I've had the 6970 a while and it's never done it until recently. I attributed it at first to my CPU voltage being too low but even since I've reset the bios settings to default it'll still do it. That's why I'm leaning towards the psu not being able to keep up.

If the psu was failing would I get lock ups or spontaneous restarts or bsods?

thought I'd update this thread with my solution (since I hate it when I find people's similar problems with no solution).

I am running two different rails to the video card now (one 8-pin from cable #1 and one 6-pin from cable #2) and it hasn't hung up in several nights of multi-hour gaming sessions. I'm convinced I wasn't providing the 6970 with enough power. Not sure why this didn't crop up in the 2 weeks or so before now that I had the exact same setup but it just didn't. This has eliminated my problem though.
