bummer. get a mac
hehe, windows tends to get full of ****. Its hard to pinpoint what the svchost.exe is as alot of applications use it. Go in to add/remove hardware and get rid of anything your sure you don't need. I used to get sick of the amount of software you get with printers, cameras etc that open up on startup. Also download a spyware cleaner, as these take up resources. There is a point of no return for pcs though, i tend to put 'my documents' on an external drive then just reformat. Its like having a new computer!
