lag when scrolling

after running the cleaner and issues features of CCleaner whenever i am scrolling in Mozilla or in folders on the computer i experience lag every time and when i scroll down too fast for it my computer beeps. So my question is could CCleaner have deleted something to do with this? (because it only started after i ran CCleaner) Or does anyone have any suggestions on what the problem could be?

Thanks heaps!

Try restarting the computer and trying again.

Yer it happened yesterday and its been turned off and on a few times...eh pretty sure there is something wrong with it thats not to do with CCleaner but its worth a shot to ask on here, thanks anyway. Can i add that my computer is going normal speed until I do scroll, or move a window around.
