Re: Graphics or Vista?
The GPU isn't 32-bit. It's your CPU that is. Personally, I have your model, but the Dual Channel version and the X series (P4S800D-X). Make sure you update your SiS AGP controller driver from Vista if you upgrade. Mine for some reasons locks up if not.
Another thing is that at the very beginning of Vista release, similar builds withthe X1650 fails for some reason. I'm not saying you'll have a 100% guaranteed fail, but if it does, you'll not be AS suprised.
Looking at your simptoms, it's your AGP controller. Mine will just do that. They pla, and then locks up. preety annoying, I understand.
