My comp was having issues recently so I took it to have it checked out, I don't know crap about comps. Well the guy said he needed to restore the computer, and used a recovery disc for it. I have windows vista. The problem was fixed, but now the comp runs slow, programs will freeze and often crash, and video codecs no longer work. Like when trying to use Windows Movie Maker. None of these things were a problem before the restore.
What do I do?
