You won't like this suggestion. I would say try uninstalling it, reboot, then reinstall it. If you really want to rule things out, and if it was mine, I would format the drive, reinstall Windows and applications. But, I also don't keep any documents, photos, important stuff on the drive of the PC. I also do backup my databases and things I do keep on the PC drive to two places, external drive and upload to cloud storage. My habits make it effortless, and stress free, to clean up the PC if it runs into a problem. But, I also have gig-speed internet. I don't know what your situation is, but at least try a reinstall, see if that does remedy it.
