Amnesia - random crashes(display driver)

[Holy2lord]

I did buy it from steam and did the check, everything is fine. The drivers are the latest, got them yesterday, also tried with previous versions. I'm using my stock clocking on my VGA as for hardware - if that was the case, then all of the game would have problems. I never had such an error before and i played alot of games. I tried increasing the TDRdelay to 8 seconds today, it worked for 1 hour ( was just circling around 2 rooms) then it finally crashed.
This problem is becoming weird.
