I have a mega annoying problem. When I play for example Call of Duty, FarCry, Team Fortress 2, etc. the screen turns off just after approx. 5 minutes. The computer runs on with the sound and everything, but with off screen. Only way is to kill it and restart. I have no option to turn on the screen again.
My machine is an HP with an AMD Athlon 64 processor 3500+, 1GB DDR, 250 GB Hard Drive. Graphics card is an ATI 4850 (brand new) and a Corsair TX650W power supply (brand new). My monitor is an HP Pavilion f1723 with a resolution of 1280 x 1024.
I do not know whether it has anything to do with the problem, but I have also seen that loading time is very long. Sometimes it takes eg. 5-10 minutes to go into a level.
It is annoying that the screen turns off and if I can help I will be extremely pleased.
