Windows 7: EVGA GTX 460 SSC driver crashing and kernel 41 (63) reboots

EVGA GTX 460 SSC driver crashing and kernel 41 (63) reboots


I really hope there is someone that can figure out how I can fix this:

I built this PC a few months ago and it was fine in the beginning. Yet recently I have been having these kernel 41 (63) reboots during games and nvidia drivers crashing outside games. Though I wouldn't be surprised if these are related. I have been reading so many suggestions on forums without fixing this problem that it is really getting me down so I thought it was time to make my own thread.

NOTE#1: I haven't overclocked anything, I wouldn't even know what I was doing if I wanted to.
NOTE#2: I set it so windows doesnt autoreboot and creates minidumps. I can't send you a minidump however because the pc crashes and reboots regardless before it makes a minidump.

OS: Windows 7 Home Premium 64
CPU: Intel core i5 2500K with stock cooler.
MOBO: ASUS P8Z68-V --> bios 0706
RAM: G.Skill Ripjaws X F3-12800CL9D-8GBXL
GPU: EVGA GTX 460 SSC --> nvidia drivers 285.38 for Battlefield 3
PSU: OCZ Modxstream 600W
SSD: Crucial M4 128GB --> firmware 0009 (no raid setup atm)
HDD: Samsung Spinpoint T166 500GB (HD501LJ)

I had crashing problems with my previous PC. There it was suggested it was my videocard so I bought the GTX 460. It didn't fix the problem, same with the PSU. So I thought I would make a whole new pc since it was outdated for (for example) Battlefield 3 anyway. I also used the 500GB HDD from my previous PC.

My curent BIOS settings have speedstep, turbo mode, bluetooth and epu disabled, fans on turbo and RAM manually set to 9-9-9-24-2 with voltage on 1.50V

What I have tried from suggestions on other forums:
- I have all updates on windows installed.
- Updating all mobo drivers (bios, lan, audio, etc)
- Disabling onboard audio
- Disabling turbo and speedstep
- Memtest86: 5passes, no errors
- Prime95 test 1 (small FFT) no errors
- Prime95 test 2 (large FFT): Kernel error reboots. Changed some bios settings to decrease the heat (turn off speedstep, intel turbo mode, fans profile on turbo). Forum suggested it was RAM issues. I manually set the RAM in BIOS to 9-9-9-24-2 and voltage on 1.5V as suggested on Gskill website instead of "auto". Ran stable for over an hour with ~66-70C then I turned it off.

And now my PC just freezes instead of auto rebooting (still no minidump though). Sugesstions are welcome.

Just downloaded Furmark 1.9.1. Will let you know what happens.
