Hi, I have an intermittent problem with startup Windows 10 x64 on a homebuilt desktop.

It manifests by the taskbar not loading, the working icon on continuously and the computer unresponsive. When in this state, I can sometimes open an application but it doesn't run. I.e. a browser might open, but there's no content. Task manager opens, but it's often blank.

This problem occurs more frequently when I switch users by logging off another user and then trying to log in under my username.

I tried startup repair and sfc /scannow but it hasn't helped.

Has anyone else seen this problem and found a way to stop it happening?
