Hello

What is the exact error code or error message?

First of all, I suggest to disable automatic system error reboot and check the error code.

Disable the automatic restart in the event of system failure

I would suggest trying the following methods and check if it helps.

Method 1:

Run the Startup Repair tool and check if it helps.
