[QUOTE="chscag, post: 871054, member: 46727"] The Apple hardware test is not always reliable nor does it do well detecting an intermittent component. I still believe the GPU is acting up. The only thing I can suggest is to try and swap out the graphics card in your G5. I'm not sure what model G5 you have but according to MacTracker the graphics card might be a nVidia GeoForce series card. You may be able to find one on eBay, however, make certain that it's the Mac version of the card. Those same cards are used in PCs but have different firmware and will not work in your G5. Regards.
