Problem: Explorer 50% cpu usage


Every day, at intermittent times unrelated to anything I do [it happens when I'm doing nothing], Explorer starts running with each core at about 50% cpu usage, and does not stop. Temperatures and fan speeds rise, fans become very noisy.

Speedfan indicates core temps rise to ~ 70 degrees C, "Temp1" rises to 75 - 80 degrees, fan 1 speed ~ 4000rpm,
fan 2 speed ~ 2500 rpm.

I have just installed Windows 10 so it seems it could not be caused by a virus/malware.

In windows 7 forums some users found the problem was caused by a corrupted file:

Explorer.exe 50% CPU usage - Windows 7 Help Forums

Since my problem is intermittent is it unlikely to be caused by a corrupted file?

I can't use the solution suggested in the W7 forums because when I kill explorer I lose my desktop.

I ran diskcheck on both my hard drives and it reported no errors found.

Any suggestions would be welcomed.

Can someone please explain why a corrupted file would cause explorer to run at 50% cpu usage?
