Need help deciphering kernel panics and possible solutions

[Spike Spiegel]

Lately I've been having kernel panics in World of Warcraft with increasing regularity. I looked around in various forums, but couldn't find anyone who has had this problem. As possible solutions, I tried re-installing the game, re-installing OS X, clearing the cache files, deleting old preferences, testing the memory, and thoroughly dusting the inside of my computer. The people at Blizzard were unable to divine the cause of the crashes from my panic log, and I have yet to get a response on my month-old post on the Apple Support forums, so I thought I'd try here.

For reference, here is what I'm running
Power Mac G4 Dual 1Ghz
2GB RAM
Nvidia geForce 4Ti 4600
10.4.11

and this is the most recent panic log

Looks like the video card.

It's a problem with your video card.

Whether it's hardware or software.. can't tell. Since driver updates aren't available to the end user on Macs, there's not much you can do about it.

I had a similar problem with WoW and an ATI 9800 Pro. It worked great with everything except WoW. Wow would cause total machine freezes, not KPs, just a completely unresponsive machine. Very annoying. Moved the card from the MDD and into a Quicksilver, and I never had a problem again. Same exact OS and WoW install.

Go figure..

You recently upgraded to 10.4.11 ?

Looks like the video driver is having problems..
