Hi Robert,
I apologize for any confusion our software may have caused, and I will do my best to explain the error you're seeing.
A failure of the PCI Express Status Test does not immediately mean that there is a problem with the associated device, but does indicate some sort of miscommunication. This is most frequently caused by a miscommunication caused by a manufacturer firmware or driver implementation (not usually a problem), but can still be caused by a problem with either the motherboard or connected device.
I would suggest running some video tests with our software as well to see what results you get, and see if the system will hang while the test is running as well.
Given the problem you were having with both the PCI Express video card and the built in one, I would think that it is likely to be a problem with the installation of Windows or the motherboard. Since it is an easier fix, I would suggest starting by completely reinstalling Windows and then try to install and run the software that was causing the crashes before anything else (other than drivers).
Let me know what you find, and if you have any questions or issues.
Thanks,
Kris
