I think i have a faulty video card, my computer will randomly restart when im installing new programs... any type of program, it will restart when its copying files during instalation. when it restarts the monitor wont turn back on. i have to shut the computer off for like a minute or two, and then turn it back on and sometimes the monitor will turn on, sometimes it wont. i have the latest drivers for my ATI radeon 7000. I am runing XP can anyone shed some light on this?
