perfmon /report shows that the Coprocessor doesn't have drivers installed. Please install the chipset drivers for your motherboard. Just FYI, the hardware ID for this device is PCI\\VEN_10DE&DEV_0753&SUBSYS_75781462&REV_A2\\3&267A616A&0&0B
Looks to me like a hardware error (but the missing coprocessor driver can cause this). I'd suggest starting with these free diagnostics:

I'll post the results of the dump file analysis is a few minutes......
