I've had my Dual 2.7 G5 since early 2005. It has been a great computer for me over the years. Noisy as hell, but great. A month ago my screen started to distort every now and then (see pics below). The computer would freeze when the screen distorted. Then when I would reboot, the distortion and artifacting would occur even at the grey boot up screen and lock up. With enough reboots it would finally get back to the desktop and be fine for a few days. This no longer works anymore. I haven't successfully booted the computer in over 2 weeks. After the distorted grey boot screen it will go black and all you see is the artifacts, never getting to the desktop. Is this a dead video card? I'm running the stock AGP Nvidia GeForce 6800 GT. If this is a dead video card, do you have any suggestions for the best AGP replacement. I'm looking for something powerful. All I'm finding are very pricey 256mb cards. I'm willing to pay for a powerful card. Thanks very much. I don't want to give up on this G5!
