So this is new. Artifacts in 3D apps, and only since updating Mobile Intel 945GM Express Chipset Family Graphics Driver from Intel.

I've already rebooted three times. They don't show up on teh BIOS screen as far as I can tell, only once Windows loads. Is that a meaningful clue? I'm happy to run tests, I just need to know which ones make sense. I have not overclocked anything on purpose, but I did install a tuning tool a while back. I want to rule out the cheap explanations before I start pricing replacement cards.
