My CPU usage isconstantly jumping up and down.?

[Ed G]

Well first of all I've had computers that run good but where always using a lot of CPU.So there probably is nothing wrong with yours.But I will tell you Skype is the worse program you can have on a computer.When ever someone brings a computer to me that runs slow the first thing I do is remove it.You have a old processor,which in it's day ran good but the older ones had to work harder.If your computer runs good what does it matter if it's using 100% of your CPU.As far as I can tell you are pulling your hair out for no reason.You could also look at the windows error logs and see it there is a problem with something running on your computer.If you have reinstalled windows 3 times in a week I would say there is a chance you could fix you issue with driver updates but you are never going to get your processor to run like a i5
