My entire system is running extremely choppy. Links don't immediately open, and I have to wait a second or so to see words that I typed.

Pages don't scroll properly which makes it very difficult to cut and paste. I can type a complete sentence and won't see it right away. Everything is running sluggish and choppy. Very frustrating.
