So I have an Asus M4A78-E motherboard which has an onboard Radeon 3300. As well, I have a Radeon 5850 in the PCI-E slot. When I try to force the BIOS to have them both activated, like I did with Windows 7, Windows 8 gives me this system thread exception error thing. The screen goes by too quickly to catch more of what it says. Does anyone have any solutions? I really don't want to lose access to my third monitor.
