sounds like your display drivers have become corrupted (or the registery cleaner removed them!), you need to find out what display card you have and download the drivers again and reinstall.
is it a branded computer (dell etc) if so you can go to their site enter the machine model number and get drivers from there
p.s. don't use registry cleaners, they often cause more trouble then they solve in my opinion, windows is pretty good at dealing with a messy registry.
