@DuilMaighstir Have you checked your Operating system for errors?
Open CMD by typing "CMD" into the run box lower left. Right click CMD and select run as administrator. Then at the prompt type "DISM /Online /Cleanup-Image /RestoreHealth" without the quotes and let it run. It will tell you if it finds and repairs any files. This will take a couple of minutes. It fix's the OS.
After the above runs at the same command prompt type "sfc /scannow" without the quotes and let it run, it will repair any file errors it finds. This also will take some time depending what it finds.
Type "exit to close CMD.
Then see if the error persists.
