I have a Mac model from about mid-2006 that came with Tiger, and I just installed Leopard recently. I wanted to play some PC games, so I installed XP using boot camp. But all the colors are distorted and wrong. It looks a lot like this, (http://www.hylobatidae.org/minerva/shards/hooray-for-computers.jpg) but on the XP side all the time. I tried resetting the PRAM, but that didn't help. I think my video card is an ATI Radeon X1600. Does anyone know a fix for this? Thanks in advance. Kevin.
