In my fervor to get rid of "junk" on my computer (because I didn't have enough space for some games) I am afraid that I might have deleted some things that I shouldn't have deleted. My computer is very slow and won't load programs like it used to. I often have to re-boot to use it. Is there a way to check or a site that will tell me what I might be missing? I am running XP.

Thanks.

I don't know what you deleted, but if you have a Windows disc you could try a system repair.

This site tells you how to do it

This site tells you how to do several different repairs. You'd want to scroll down to the part about booting off the Windows disc. He has pictures of what you'll see when you do the repair.
