I'm having a problem with my girlfriend's PCs where CPU0 gets a constant 30-50% load. I'm not sure which process is using it but it keeps the CPU on boost clock at all times, and fans ramped up a bit. This is annoying since I can't even be sure of which process uses this specific thread.
I checked the windows event logs and didn't see any error or warning. Is there a way for me to find which process is responsible of this ? I see that Hardware Interrupts stays fairly high with a constant 2 to 3% usage.
The PC is running Windows 10 with the latest update. Drivers seem up to date and the problem surfaced about 2 weeks ago.
Edit: As harrymc suggested in the comments, it doesn't do it in safe mode however. Could it be a driver issue ?
Thank you for your help, you will find below some screenshots to illustrate my problem :
HWMonitor, you can see that CPU0 is at 34% load, preventing the CPU to lower it's clock.
