freezes

When I play the ut2003, it will randomly crash making my pc either reboot
alone or give a blue screen with IRQL_not_less_or_equal error.
I do not think that it is an irq conflict, since I have removed scsi
controller, sb.live in order to assure that the trouble isn't up to any irq
matter. Here is my config:
xp2000+
gf3 with detonators 30.82 (i tried 40.41, 28.32, 29.42)
512 mb ddr
a7v333
windows xp pro + service pack 1

I installed latest via version.
I changed hard disk after formatting it.
I disabled on-board audio to avoid any other irq conflict.

Anyone might think about a solution ?
