Sarejac,

If the WHEA_INTERNAL_ERROR error is caused by a corrupt system file, the SFC scan will fix it.

Here's how to run SFC scanner on Windows 10:

Right-click the Start Menu button and open Command Prompt (Admin).
Enter the following line and press Enter: sf c / scannow

Please wait until the process has finished (it may take a while).
If the solution is found, it will be applied automatically.
Close the command prompt and restart your computer.

Unfortunately I can't get windows to open tone able to do that. It won't open in safe mode either.

So computer suddenly randomly started and tried the SFC fix.

However, it has not worked and blue screen loop has restarted.
