When i play games or do something that pushes my computer such as google earth, or CounterStrike:source, my computer crashes and says OFF MODE IN 5 SECONDS, then it turns off and i have to restart the computer. The computer does not toatally shut off..the tower is still rining but the moniotr is like frozen, i tried turning the monitor back on when it shut off and it said OFF MODE IN 5 seonds again. The monitor will not turn on until i restart the computer. I re-installed the drivers and still no go. A while back when i talked about this problem a Computer repairman said it was the powersupply, he wasnt sure but that what he suggested. Beofre i go putting the money down for this i would like to get some second opinions on what i could do. Here are my PC specifications: -AMD XP 2.0 gig -RADEON 9800 pro 128mb video card -140gig SADA(sp) hard drive -MSI KT6V chipset -ViewSonic E90fb monitor -L and C power supply 350watt any help appreciated...
