This is a new probelm for me. I thought I've seen them all. About every 10 mintues my computer screen goes blank. THe computer is still on and the monitor light is on but the screen is black. I have to reboot it for it to come back on. I'm now sure where to begin troubleshooting. Could it be the video card, the ribbon to the video card, or the driver, or God forbid could it be the CPU heating up? HELP Please!
