My computer keep going into stand by for no reason. I then have to push the power button and the computer goes back to what i was doing right before it restarted. It has been mostly been doing it when i am playing videogames, like nba live 2005 and command and conquer generals. Both game run perfect at high resolutions so i know im not over working my pc. I have a AMD Athlon XP 2.16 GHz, 512 mb ddr ram, and visiontek 128mb ati radeon 9550. Can anyone help me?
