Windows 10: Windows 10 Pro Upgrade Fails. Troubleshooter Fails.

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

 

What is causing Prime 95 to keep failing all the time in the first 10 minutes?

...and what will be your next step if THAT fails to make Prime stable? More volts?

I would think you would want to be using the LEAST amount of volts possible (for heat and longevity issues). That's why I suggested you use a more scientific approach to troubleshooting your instabilty. Meaning, IF your RAM passes 10 loops of MemTest with no errors at the speed you are trying to run, AND Prime continues to fail, THEN consider giving a bump to NB, FSB and Vcore (in that order).
