Kernel Trap

Question

Lately, every day or two, my computer's screen will suddenly have a horizontal ripple travel up it, leaving behind a message saying I have to restart my macintosh, and locking up everything that I was in the midst of doing. I restart it and everything is fine for a while, then it does it again. The error report it gives me upon startup is this:
Unresolved kernel trap(cpu 1): 0x400 - Inst access DAR=0x0000000001037B8C PC=0x0000000000000000

Anyone have an idea what I can do to fix this?

Answer 1

I will guess one of two things. The good one would be that there's a conflict with your Pace Anti-Piracy software. If it came with an uninstaller, use that and run without that for a while.
The bad one would be something with your video card. The kernel extensions in the backtrace there are all related to your video card, and it could be the culprit of the Pace software isn't.
