Windows 7 Kernel error 41 while paying "intense" games

[NoviceHardware]

I have been running into a problem where my PC will shut off (then automatically boot back up) while playing "intense" games. I checked my event logs and it looks like I'm getting kernel error 41. I have tried the standard stuff to fix this issue, uninstall and reinstall drivers, blow out PC, re-set my GPU, defragging, repaired windows, updated windows, and cleaning registry. The odd thing is that my PC runs perfectly while I'm not playing a game, I can use it for weeks with no problems but once I try to play a game it shuts off and boots back up, after it boots up it works fine (till I try to play a game again). Months ago I was able to play games (include the ones that are now causing it to shuft off) just fine and I was not running into this problem. I recently (within the hour) ran a Prime95 stress test (In-Place large FFTs) for 30 minutes all cores at 100% with no problems.Also I had some monitoring software running when the crashes happened and tempatures were all in acceptable ranges, any assitance in this issue would be greatly appreciated

event 41 is the result of a report windows runs at start up. If it finds PC didn't shutdown properly previous time, it creates an event 41. Its a reaction, not the cause. It means windows doesn't know why it restarted and points towards hardware

download hwinfo32,
install and open it,
check "sensors-only",
click "run".

what are your voltages like? might want to run this while playing one of those games and see what it shows. See what temps you get as well

could run free version of http://www.memtest86.com/ on your ram, one stick at a time. Any errors are too many, stick needs replacing if you get more than 0 - memory normally causes freezes, not restarts though.

It can mean a faulty PSU. if you didnt hold down the on/off button
