I have the late 2006 CD iMac (20"), but ever since upgrading to leopard, it has been extremely crash prone. It would almost certainly crash every time i tried to run portal or TF2 through crossover at first, but now it crashes while doing regular things like surfing the net. I have already repaired my disk and repaired permissions. A friend of mine who is a certified apple tech said to clear my PRAM, but i'm not sure it worked properly because it didn't reboot 3 times even though I held the key combo for the second boot. When it does crash, everything, but the cursor freezes. I have never had this problem until upgrading to leopard. Also, (i think it is a thing with radeon x1600 and x1900s) after upgrading, strange lines randomly appear every now and then, and a lot of games crash the system, while doing something funky to the screen.
Somebody please help, but don't even think about suggesting to re-install os x
