Runs, if you or someone else has a problem and are using Windows, try doing a System Restore. It takes your computer to an earlier time when it was running fine.

Go into My Computer, Control Panel, opens to Pick a Catagory. Go to Performance and Maintenance. On left side, See Also, go to System Restore, click on it, opens to Restore my Computer to an Earlier Time, go to next, pick an earlier time when your computer was fine, could be a few days or a few months back. You will not loose any new files.

I did it a few years back, when my some type of virus attached some programs to my desktop and I could not remove them.
