I was using Playerunknown's Battlegrounds and encountered a blue screen. My computer won't start Windows now. I attempted safe mode, a reset, and startup repair, but nothing helped. Any suggestions?

There is a solution on this thread that may work, but just a shot in the dark... https://answers.microsoft.com/en-us/wind...a43dfe5978

I also tried that, but it didn't succeed. Would completely erasing the drive help? (No backup available, but it's safer than a non-functional computer.) EDIT: Attempted to wipe the drive, but it failed and rolled back the changes...

There might be a solution from someone smart to suggest, but if not, and you need to erase the drive, use DBAN. It won’t cause any errors during the wipe. Link: https://dban.org/

You can restore Windows by using a bootable USB drive during installation. This method allows you to reinstall the operating system from scratch.
