My Computer Slow, Can't restore or set restore point

I have XP Pro on a Dell. We recently added Small Business Server for a SQL application we have. Now My Computer will not launch for about 5 minutes. I can't right click at all to bring up properties, it too takes long. I discovered automatic restore points have not been created although it is marked to do so. I can not create a new restore point, I just get the hour glass for a while then it goes away and nothing happens.

I'm new here so please tell me if I'm doing anything wrong. I was glad to find the forum.
thanks!
