This is the fourth install and I'm running out of things to try. fresh install of Win2k, SP2, Det 12.83 drivers, DX8, AMD 766 PCI bridge driver. Didn't install the AGP filter as it's giving other people fits. I cranked up UT and BSOD'd again in second game giving me a "Kmode _Not_Handled" serror with NTOS Kernel at the end of the string.
