Hi, Please update the BIOS, display card and other device drivers to the latest version and check if the issue occurs. Also, access Clean Boot to see if certain software and service is causing the issue. If the issue disappears in the Clean Boot environment, you can continue to narrow down which entry is causing the issue.
