Computer Slowing Down And Freezing?

Recently my computer has been freezing and slowing down a lot when I use it. At first I thought it was a driver issue since my computer only freezes whenever I am watching a video or listening to music, I think I installed the right driver but my computer is still freezing ( a strange side effect from the freezing is if there is any audio, it will slow down and start to stretch out). After a few minutes it will revert back to normal like nothing happened.

Also my computer isn't running smoothly anymore, many times when I type, the words jump to completion. When I scroll, it jumps and doesn't smoothly scroll down the page. I tried everything from defragging to updating every driver and program possible and still the problems persist.
