I tried that method theog and still had the same results: Freezing at the teal windows 8 logo screen.
For what it's worth.. I have the ASUS A8N SLI premium and it's working fine with W8 64bit.
But I did have to battle the dreaded teal window when I tried to upgrade to a newer video card.
I had XP on the system with an EVGA 9800 GTX video card. Upgraded to W8 64 bit, clean install to new 120 GB SSD.
All worked fine for a few days.. then I decided to "tinker". I had a spare EVGA GeForce GTX 470 that I figured I would pop in the system. Upgraded power supply from 500 Watt to 650 mainly because the GTX 470 needed two PCI-E power plugs to operate and only had a single on the old supply. ( plus on the low end of wattage anyway )
System posts, then when going into W8 os, it sticks on the teal window. Reboot, says it's trying to repair, never does. Reboot, just teal window. Ck bios, all looks good.. but never can boot. Can't even get the DVD to boot with W8 disc in... just spins for awhile then sits idle.
Reinserted old video card, boots, says trying to repair, then gets to the restore page... I just cancelled and rebooted again and all is fine again.
So, not sure what is causing this... my GTX 470 works fine in my other system. I even tried another GT550Ti card in the A8N mobo.. same thing with the teal windows freezing.
Perhaps those newer cards draw too much current for the PCI bus? Maybe the memory in the cards is to much? ( wouldn't think so ) But for whatever reason I can only get the old A8N mobo to boot into windows with the GTX 9800.. 512mb memory btw.
