I had a friend who has a system of which Window XP Professional, a GeForce 440X Graphics card, 80 GB HD. Basically he had an advance system. His system work fine until recently the monitor start shows problem. After working a while, his monitor start to turn into different color and reboot itself. It happen quite frequently that he want to buy another monitor. I came over and check out his video card driver, and other components to see whether there is a conflict or over heat, but can't seems to find anything wrong with it. I asked him whether he had install any new programs or devices, and he said no. I'm at a lost, any advance before he give up on his monitor? Thank in advance. Sincerely, John Loc.
