[smiley=huh.gif]After the computer has been running fine for a while, without warning the monitor image turns into a series of vertical, broken white lines with some color mixed in. I've tried 3 different monitors and 2 different cables. I've also updated the drivers and even tried a 3rd party driver. Nothing's helped. My video card is an ATI All-in wonder 9600. The whole system is about 3 1/2 years old. I've only been having trouble for a few weeks. If you restart the computer, It's OK again for a while. Any ideas? Thanks.
