What extension do they have? (the three or four letter name after the filename)
Have U tried opening them with another player?
Open them with openwith or drag them to another player.
Maybe it's an association issue.
In any folder, go to Tools> folder options > and under File types see under your extension , what program is set to open them with. If not, U choose a program.
Check if U didn't deleted your codec pack.
Reinstall the VLC media player.
Run a Malwarebytes scan, just in case.
Oh, and the next time you do some cleaning, U could use an utility like CCleaner or Disk Cleaner in Windows.
If this is not it, we'll see.
