[QUOTE="chscag, post: 870264, member: 46727"] Sounds more like a GPU problem - not a virus. Run the Apple Hardware Test on your machine: [URL="http://macosx.com/forums/howto-faqs/299888-use-apple-hardware-test-other-diagnostics-test-hardware.html"]Link[/URL] The AHT may or may not identify if the graphics processor is at fault especially if it's intermittent. There's always a chance it could be something else such as the display itself. Unlikely, but to make sure, try attaching an external monitor to your G5 to see if it displays the same symptoms. Regards. [/QUOTE]
