Windows 10: PC randomly restarting with Hypervisor error

I recently built a new PC, and I have been unable to use it because it will randomly crash and reboot during any heavy task. The error "The hypervisor did not enable mitigations for side channel vulnerabilities for virtual machines because HyperThreading is enabled. To enable mitigations for virtual machines, disable HyperThreading." appears in the Event Viewer shortly before each crash. I cannot find any minidumps, as the computer has no time to make one during a crash. I've run RAM tests multiple times with no errors. I am unsure how to fix this, and would appreciate some advice!My specs are

PC Randomly Restarting after installing new Ram!

Tried your suggestions, but still had a restart! Also ran memtest overnight (13 hours according to memtest) and had no errors! Also ran Passmark Burn in test for a couple hours testing everything and had no errors or restart. Could fitting the new ram have triggered something to go bad like my mobo or psu?

 

Computer randomly has black screen and restarts

Taco this could be software also. Before you get all crazy, do as Erocker suggested. Find out the error in the Event Viewer. Look for the faulting module and the error code itself. Also check the reliability monitor. At the bottom it will have "View all Error Reports". Post a screen of whats in there if anything.

This could be a simple as a bad driver install.

ALSO have you downloaded or installed anything lately? STAY OUT OF THE DAMN BIOS UNTIL WE KNOW THE ERROR! lol. I know you. Baby steps boy, baby steps.

 

HyperVisor Error

I have attempted to disconnect and reconnect cables with the same issue. When turning off intel virtualization it crashes randomly. Also, when trying to update windows it errors out. When using a windows ISO file to update it crashes with a green screen HyperVisor error
