I suppose everyone already knows this but it took me 4 months of troubleshooting to figure this out. If your Mac is acting strange freezing hanging crashing (which I¹ve never had in the 20 plus years of using my Mac¹s) Your problem is not your Mac per say but maybe the video card. I have a 1st generation Mac Pro Quad core with an ATI Radeon 1900 video card and it turns out this is a well know problem for Mac Pro¹s Apple now has a replacement card the Nvidia 8800 GT for early Mac pros. So if you have one of these video cards in your Mac Pro be aware...
