BSOD CPU and CPU fans at high speeds when playing games.

Just ran prime95 torture stress test for just over six hours , is that sufficient?>

okay so to sum up your original post - no errors in all tests , all instructions followed.
back to square 1 D: .
going to install a new beta driver just incase theres a one off chance of it helping.. i dobut it though.

If a reinstall of windows doesnt fix the problem , am i safe to say theres a good chance its the P.S.U?

-btw thanks alot for your help so far.

updated to latest drivers , no luck as usual , the game crashes before any image appeared on my screen( the usual case) on reccomended settings.

It was worrisome that after your computer crashed, the fans then went full speed.

If you are crashing from heat it may be because the BIOS is not handling your fan speeds correctly. You may be able to fix it by installing SpeedFan and specifically setting your fan speed(s) to max, at least when you intend to play games...

There may be an option in your BIOS that allows better fan controll as well.

THere have been cases of BIOSes and GPU drivers that improperly handle the fan and cause such problems.

The actual allowed temps are of course CPU and GPU specific. I.e. my GTX480 (a 230 watt beast of yore) runs at 80-90C with dual monitors when playing Skyrim and that is "normal". The CPU runs at about 45C. Never had any heat related issues...

only 50 % of the time the gpu fan will increase like that , other times it will crash indetically but fan speeds will stay the same , ill check my bios fan settings now.

set my gpu fan speed to 100% on msi afterburner.. same thing happened game crashed straight away

Ok.. Yeah if it's crashing /instantly/, then it's likely not heat, or atleast not heat any more...

Either software (Drivers) or hardware that's gone bad, after all your testing the only hardware I'd suspect is the video card itself atm.

You have any alternative video cards you could swap in for a bit?

no i dont , would integrated motherboards graphics surfice?
