Everytime I play one of my newer games (Crysis Warhead, Mirror's Edge) the screen freezes after 1-10 Minutes.
The sound is still there for a few seconds and after this the screen takes one single colour, usually in the tone of the last displayed frame.
I can't find any pattern in the intervals of time this keeps happening, it just always does. Setting graphics to lowest or highest makes no difference.
But there are actually levels/areas in which I have the feeling, this happens less often and after I'm through this part of the game, I can go on playing for a while. Don't know if that helps solving this.
CPU: AMD Athlon II X4 630 Box 4x 2,8GHz
Board: ASRock A770DE+
Videocard: Club3D HD4670 512MB
Memory: 4096MB-Kit GEIL Value PC2-6400 DDR2-800 CL5
HDD: Samsung SpinPoint F3 500GB, SATA II (HD502HJ)
Case: Xigmatek Asgard
Power Supply Unit: Xilence Power 420 Watt / SPS-XP420.(12)R
Operating system: Microsoft Windows 7 Home Premium 64-Bit
Tested my system with Furmark and Prime95 and the temperatures were not that high.
And I guess, if it was a temperature problem it could not happen after only one minute of playing.
Memtest could not find any problem with the RAM.
I installed new graphic drivers, but I'm not sure if the old one is deleted.
I'm on my wits' end.
Thank you for your help!
