PC crashes while playing Call of Duty 4

[wa1ker]

Built a new pc about a 1 and a half weeks ago. No problems at all until i started to play call of duty 4. As im playing the game usually after about 2/3 hours of playing on and off suddenly the monitor will just go black onto stand-by like the PC is turned off, but its not its still on. And the sound just repeats its self in a loop like its crashed. The only way to fix it is to restart the PC, but the problem keeps re-accuring. At first i thought it could be a overheating problem, but my GFX card hardly goes over 45C and the CPU around 34C.

Bump, seem to be getting worse and happens much more frequent.

Make sure you have the latest drivers for all your hardware, and the latest patch for CoD4.

Also the other thing is are you running a firewall or something that might be asking if the application can perform a certain task. I know that Comodo firewall can be a B***h like that sometimes.

this was happening to me, although my card is better, I had no heat issues, I had to downclock my card, didnt see much difference in performance but it stopped the crashes. I love that game
