My computer regularly crashes when playing games, this usually occurs anywhere between 5 and 30 minutes though on the odd occassion it will last longer. The usual symptoms are that the screen freezes for a while then the screen goes blank. The PC has to be restarted. I have checked the System Requirements Lab (stickied in this forum) and all the games I have tried return as Passed. Specs are: Processor: AMD Sempron(tm) 2400+, MMX, 3DNow, ~1.7GHz Memory: 1024MB RAM DirectX Version: DirectX 9.0c Graphics Card: CONNECT 3D RADEON 9550 (256 MB) Can anyone assist with my problem? Is there anymore information that is needed?
