I recently purchased a used ATI Radeon 7000 64 MB AGP video card in order to upgrade my Power Mac G4 Sawtooth. This is the Mac Edition card, not a reflashed PC card. I followed the seller's instructions to download and install the drivers and the ATI display panel. I shut down the computer, removed its Rage 128 Pro card and installed the Radeon 7000.
I turned the computer back on, it booted up okay and displayed the desktop and apps just fine. The problem came when I tried to play video -- I inserted a DVD as a test. The OS opened DVD Player and started the movie, but the screen broke up into patches of pixels and froze up. I couldn't escape or force quit; I had to turn the computer off.
This also happens when I bring the computer up from sleep mode. The screen breaks up into the colorful pixel patches and freezes up.
Additional info: computer running OS X 10.4.11. Sonnet 1 gHz processor, upgraded 1.25 gb memory. Computer monitor is an acrylic 23" Cinema Display, attached to the DVI port on the Radeon 7000 using Apple's ADC to DVI adapter.
Anyone have any advice on how to fix this?
