A few days ago, I noticed that my CPU is running high causing the fan to run almost constantly.  I noticed in the taks manager and resource manager that dllhost.exe keeps popping up and then terminating, and WMIprvse.exe also runs sometimes holding onto 30% of the CPU for hours.  I've also just had (while I was writing this) a blue-screen reboot (the first so far).  With all the crypto-currency mining going on, I wonder if I've got something living in my PC.  

 

I'm using the latest version of Windows 10, creators edition I think its called - I checked and applied all updates.  For Anti-malware/virus my PC has Cylance and Microsoft Defender.

Hours?  Something is hosed as WMI usually only runs for short periods.  Check this article and see if it helps.

You are going to have to search thru Event Viewer to try to figure this out  While in Event Viewer you may be able to garner some addional infor on the BSOD..
