As i think I am the only one here at the moment(3.43am), have you tried the easy things like clearing your internet history, removing unused programs, defragging the C Drive, disabling some programs on startup?
if you have to many apps running, then it may slow your pc down.
You could also try checking the inside of your case to see if its accumulated alot of dust and fluff which you can carefully try vacuuming it out.
I don't know what the bleeping bit is? but that I shall leave to the more experienced later on in the day.
