You're right..what a puzzler.

A couple of things to try.

In BIOS, make certain ram settings are for 133 and not 100. Your board defaults to pc100.

Power Supply may be too small.(I know, 300 is large but AMD's take a lot) I'm running a 250 with a AMD 1GHz TB and I lock up in Diablo as well. Just a thought.

Another tech(Mustang) was concerned that maybe you didn't update your agp drivers. Try this link.

Good luck!
