I put all this together yesterday, and am having very strange problem. I can only describe it as trying to watch a DVD on your tv, with the tv on channel 4 when it needs to be on channel 3. The display is split in half horizontally, with either the bios or desktop displayed in both the top and bottom sections. The display flashes in and out, and is striped vertically with pink and white stripes. I got it to go away only on the desktop by cranking the resolution up. But the bios still does it. The problem was there with the shipping bios 0401 I think, and is still there with 0901 (latest?)
I have installed all chipset drivers and VGA drivers, even did a new install of XP, and am stumped on what to do next.
