So far as I can tell, it is a problem with the motherboard drivers. The m5a97-r2 has not had a chipset update since window 8 (not 8.1). I contacted the support team about when the drivers would be updated, and they said it would be “soon,” of course that was back in late-August. There must be some sort of PCI bridge error between the GPU and CPU. That’s the only way I can explain it. I just loaded a secondary hard drive with Windows 7 and switch to that OS for all of my video editing.
