N.H.B. I have already built a couple of rigs just like yours. Usually I have only seen them sieze up like that if the "chipset clock mode" setting in the BIOS is set to "performance". I don't know if thats your case but it overclocks the PCI/AGP bus and causes lots of problems. I generally use the SIS 1.13 AGP drivers. Have you tried taking out one or two sticks of memory temp. to see if it goes away? Sometimes the board can be unstable with 3 memory sticks at 333MHz+ speeds.
Edit- Have you also tried upping the DDR memory voltage and the AGP voltage?
