I used the website for MY computer and it is a cool website. Unfortunately it wouldn't work for my wife's computer. I did a little digging and found that her machine is maxed out at 256MB!
Aren't Norton applications usually resource hogs? I think that I will uninstall Norton Internet Security and anything else that I can find and see if that helps any. I might format the hard drive and reinstall just the basics. Would it help to NOT have multiple users? I'm using Windows XP - should I go back to the previous version of Windows?

I realize that we have wound up off topic for this forum. Any response to my questions above would be appreciated and you can close the issue after that if you'd like to.
Thanks again for all of youe assistance.
