I posted before about my mac pro freezing. Ive determined that it wasn't freezing, but it was loosing video. when it freezes I can still use the volume keys to raise and lower volume and I can hear the game music of the game I was playing continue to play. I guess I have a faulty video card? I'm going to update the drivers and see if it happens again.
edit: problem...the only drivers I can find are for the G5? http://ati.amd.com/support/drivers/m...G5Updater.html
