Your PC has been running for about four years and is becoming slower, taking longer to load and showing strange behavior such as crashing when you switch tabs or play games. Microsoft and Blizzard reported multiple errors that they couldn't resolve, suggesting a need to wipe the system. You're considering an external hard drive as a backup, which might help stabilize things. If you need guidance on restoring or resetting it, let me know!
Performing a factory reset will bring you back to an earlier state.
Instead, revert just the effects on Windows parts and any software after the chosen restore point. I still think a factory reset is preferable here.
