CCleaner HELP

Okay so last night I apparently deleted something that I shouldn't have because now my computer screen looks funny and everything is huge and blurred and in weird and sometimes inverted colors. I have tried to attach a screenshot of my "new" and not improved home screen. Hope it works and please help me out. I dont even know what I deleted that screwed this up.
