I am getting very close to chucking this motherboard out the window! I stripped it bare and used an old card to enable the monitor. I reset the BIOS and then I implemented the BIOS update and it still is freezing. I now know that the fault is not being caused by the video card, therefore the fault must lie with the board. The only thing I can think of doing is trying to take screen shots but there is no guarantee that the machine will stay on long enough for me to do that. I will try safe mode before this but as so much stuff is disabled in safe mode I'd say it will just last about 5 minutes longer before crashing.
Did you notice the note about the Bios update. It states "Load Optimized Defaults" Also, go into the memory section and make sure your memory is Ganged, not Unganged. Set all your memory to "auto" Set your date and time as Vista does not like it when it say's 1/1/2000. You can set your CPU multiplier to 9 or 11 but I would not try tweaking anything else. You still might have memory issues as that problem has not been resolved by Gigabyte. Are you sure your board is not grounded somewhere? I will go and review your setup one more time to see if were mssing something.
