Try loading Optimized BIOS defaults. Also try clearing the DMI data. You should also try updating the bios with the latest availiable. When updating the bios make sure it clears/writes all the blocks of the bios. Not just the main ones. Also try disabling ports such as Serial and Parallel. There might be some other device using up IRQ10 (which is used for video devices). You might even need to install latest motherboard drivers... or even... reinstall Windows.
