Hello and welcome to justanswer, My name is ***** ***** i will be assisting you today,
I'm sorry about the issue, please boot up into your computer, and back up any critical files you need so you don't loose data then do a system restore. That takes your computer to an earlier good state.
Right-click (or press and hold) the Start button, and then select Control Panel.
Search Control Panel for Recovery.
Select Recovery > Open System Restore > Next.
Let me know the results please
Has everything worked out please?
