If these suggestions don't work, then you could always use your backup to restore it.
If you don't have a backup, then you could backup your data and then do a Factory Settings Recovery.
I don't know which HP you have so I had to choose one, in which to give you instructions. What you see here may not be your laptop, but it may still work the same. If it doesn't work, go to the HP website, click on SUPPORT, after putting in the information for YOUR laptop, click on "Download drivers and software", scroll down and look in the left column for the link for MANUALS.
