Same thing here:
MSI Neo2 Platinum
AMD 3500+
XFX 6600GT AGP
Win XP SP1 + 67.03 drivers, all the drivers for the mobo, sound etc are the latest.
Tweaking the Fast Writes and AGP speed didn't help, downgrading hardware acceleration didnt help.
ALL games do not run in 3d - video output is lost and a reboot is teh only way out.
