If you can boot into Windows 10, open the new Settings app (the cog icon in the Start menu), then click on Update & Security. Click on Recovery, and then you can use the 'Reset this PC' option. This will give you the choice of whether to keep your files and programs or not.
That should ‘reinstall’ windows and sort your problem if it’s software related, plus you keep all your old files.
I have perm disabled it mate. Seems to have been one of the issues so just left it turned off.
Seems ok now.
I'm going to get an ssd and use the hdd I have now in place of the CD drive. Will run the OS and a few other programs from the ssd and have all pictures etc on the hdd.
Is that a common thing to do?
