Monitor Randomly Turning Black and Fan Speed accelerate to the max. When it happens i can't do anything besides hard shutting down the pc/

Before Shutting down i got those 3 warnings from event viewer:

1.

The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID 

Windows.SecurityCenter.WscBrokerManager

 and APPID

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.

Error

The previous system shutdown at 11:49:16 on ‎02/‎08/‎2024 was unexpected.

Critical

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Error

Audit events have been dropped by the transport.  0

To make things clear. In every pc crush the Hypervisor warning appeared before and that's why i unchecked the option for virtual threading/machine in the windows features.

Checked the dump files from May and June and attached the possible indicator for system crush.

I attached the Intel Processor test result also. All passed.

The crushed happens randomly no matter whether im playing or browsing the web or write programming code.

Tnx in advance
