I've had this problem before, but it was with an Asus P5B Deluxe which had oodles of BIOS options that could 'fix' the issue, at least until the next reboot. Let's just say this Dell Precision 390 has nothing in the BIOS to address this and my 9800GT has gotten stuck at x1, which probably explains why my points are about 2K off in [email protected]. It's a i975X based motherboard. It's obviously not overclocked. (it's actually underclocked as you can't disable C1E) Any thoughts?
