Yesterday when I got home I plugged the new mobo in, and wonder of wonders it would post.
Last night I had birthing classes, had to go get our daughter from Grandma's after than, so at 11pm I sat down to finish building the workstation. Vista kept treating me to bluescreen/stop errors after copying files. Doing some research I found that many motherboards + Vista64 have an issue booting with 4gb of ram installed, so I eventually took some RAM out and got windows installed. There was a hotfix for this issue but I kept having hard lockups in Vista. Long story short: I flashed the BIOS after about 4 Vista lockups, Vista insisted on using it's "standard VGA driver" instead of the Vista 64 driver that came with my 8800 GT. I'll have to see tonight if Vista is happy with the new BIOS and/or the NVIDIA unified drivers when I try that.
Stupid computers...
