I usually am on my computer a lot listening to music and playing games. When one day I just turned it on and then went to go get something to eat. When I came back my computer was running like I was playing a game on high graphics. I turned on the task manager to see what was going on and there was a lot of com surrogates on. Now it takes for ever for anything to start up. Getting on the internet is rough and takes a lot longer then it used to. I really don't know anything about the inner workings of the computer and I need help.
