Firtly i will give you some info about my pc:
proccesor: intel core 2 quad CPU @2.40Ghz
Ram: 4GB ddr2
Graphic card: Nvidia Ge Force 8800 GT
Graphic card's drivers
Windows 7 ultimate 64x
So my problem:
While i am playing a game (windowed mode mainly but happened of full mode as well) after some minutes (about..20) the monitor loses signal.Which means i have sound(not sure wether it just repeats the same part over and over again or the sound actually goes normal) but i get black screen and the monitor says "No signal'.
Weird part is that it doesn't happen to all games.So far it happened only on CoD:Black ops while football manager 2010 and pro evolution soccer 2010/2011 work without any problems.
If you need any more information let me know.
Thank you in advance
