I just bought this machine and did a fresh install of windows, now I went to play a game and just randomly restarted on me, tried again did the same thing, thought I'd test out 3Dmark to see if I could replicate the issue and I get it again :( , with Vantage and 2011 3d mark versions. I turned off automatic restart but for some reason it wont show me the blue screen, it just kind of halts on a black screen when I did that instead so all I have got to go by is what I get when I come back to windows with the "Windows has recovered from an unexpected shutdown" with its error which I'll paste here below, any help would be GREAT as I have no idea, I did a quick google search and someone (in yahoo answers) said it was registry related, tried 2 cleaners / fixes didn't do anything, same problem still. Oh PS I tried installing the latest drivers and flashing the latest bios also, still doing it :( Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 3081 Additional information about the problem: BCCode: 116 BCP1: FFFFFA8013ABA4E0 BCP2: FFFFF8800FD25AA4 BCP3: FFFFFFFFC000009A BCP4: 0000000000000004 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\043012-18174-01.dmp C:\Users\V\AppData\Local\Temp\WER-62041-0.sysdata.xml Read our privacy statement online: http://go.microsoft.com/fwlink/?linkid=104288&clcid=0x0409 If the online privacy statement is not available, please read our privacy statement offline: C:\Windows\system32\en-US\erofflps.txt

Additional Information! I download BlueScreen View, got the Bug Code 0x00000116 (so the same as the 116 above) and the additional information. Caused by driver : dxgkrnl.sys Caused by address : dxgkrnl.sys+5d000

The Stop 0x00000116 (VIDEO_TDR_ ERROR) indicates that an attempt to reset the display driver and recover from a timeout failed. The dxgkrnl.sys file is a kernel driver that controls the underlying video driver stacks to provide fully featured display capabilities. Try downloading and installing updated drivers for your video card, if available. Bye.Luigi Bruno - Microsoft Community Contributor 2011 Award

Ah sorry I did mention I did have the latest drivers installed etc (Nvidia drivers installed straight from the website), thought it might have been an issue with the drivers so tried the previous version, same thing, then I just tried removing them all (even with driver sweeper etc after the uninstall) and installed the straight windows update driver and STILL does the same thing :(

Found the problem it was an overheating issue I think, I'll update if its not but I did the burn test and the video card reached 105 degree's with the fan speed full then system rebooted, gave it a clean (as I bought it off someone else) and the dust omg, now it doesn't reach over 65 degree's at max fan speed.
