So far I have system & chipset drivers, on-board audio, on-board lan and Nvidia drivers installed and I did a primetest for atleast 45 minutes after installing each driver. I decided to try verifier at this point and I got BSOD, caused by usbfilter.sys. So I updated with the AMD usb fliter driver nmsuk gave me and now my computer's video signal and usb power is going out after 5-10 into verifier. Not really sure where to go from here? One thought I had is verifier is failing because all drivers aren't updated yet. Doesn't prime stress drivers though? I did two prime blend tests for around 5 hours each and a few more for 45 minutes and had no errors, why does verifier still fail?
