Hi Robbie,
Issue reported: Windows 11 crashes when inactive, hardware error showing (Error unknown)
Observation: It seems that you are using a new machine with Windows 11 however it is not validated that if the BIOS and other latest drivers are installed in your machine or not. It is possible that we can buy a new machine with outdated drivers.
Troubleshooting
Step 1: We first need to validate if the machine is installed with a latest BIOS version supported by the OEM, this can be validated if we visit an OEM website and search for supported Drivers and BIOS version for a specific model.
After we update the supported drivers and BIOS version, restart the machine.
Step 2: We need to check for Windows Updates and optional updates under Advance option under Windows Updates in Settings. We need to download and install all updates ensuring that we have all hardware and software updates installed followed by a restart.
Step 3: Open Device manager and check for corrupted drivers, they appear with a yellow triangle with a black exclamation mark or a red mark. If we find any corrupted driver(s) please update them, if not getting updated, uninstall them and reinstall the same/similar drivers, those should be available on OEM website.
Step 4: Open ‘Command Prompt’ with administrator rights and type ‘SFC /scannow’ and hit enter, this will scan if there is any software corruption in your machine that required to be fixed. Then in the same CMD Window Type CHKDSK /f and hit Enter and then type ‘Y’ followed by an Enter and then restart your machine.
After performing all steps mentioned above, please update with your findings!
Sincerely,
CK
