Conenct the harddrive to another computer and take a backup and reinstall windows. To me this is the only option to fix without loosing the data.
This is a discussion on Windows 8.1 64bit Problems within the Windows 8. forums, part of the Operating Systems category; Hi Guys If anyone knows of a solution on fixing my problem ...
If anyone knows of a solution on fixing my problem I would be most grateful. The problem is I have missing and possibly not quite sure corrupted files in Windows 8.1 OS. I have tried to do a System Restore, no good. Also have used Reimage software and Tweaking Windows.com without any success. Does anyone know of a solution to repairing or replacing files without having to Reformat and loosing everything. I have tried Windows PC Refresh. It doesn't work it asks me to install Media disc in to PC. which from then on I will lose everything. Any miracle thoughts guys Ta. PS System is clean no Viruses.
Had exactly the same problem, tried allsorts from internet, got reinstall discs from eBay couldn't fix it.
So I did what deadpool suggested, backed everything up and reinstalled windows it goes back to having just got it out of box for first time.
But it fixed the problem
