My computer will freeze when playing 3D games such as World of Warcraft and others. This only happens when playing the games, i can open web pages, word documents, and most videos with no problems, but when i open a game i will be playing for no more than 2-3 minutes then the screen freezes. I can hear music in teh background and if u press keys the u can hear the character is doing them but the screen is completely frozen. After a minute or so of this a blue screen will sometimes pop up and other times the game and computer remain frozen untill i restart. My system is a Dell XPS 400 Intel Pentium D dual core 3.2 ghz 2gb of ram GeForce 7900 GS graphics card I have downloaded and installed new drivers to try and fix this problem and it doesn't help. There are other dump files but they are oo big to upload to this sight.
