slow computer, defrag doesn't work, many error messages

I have Windows 98, Pentium 1 - 233, all installed by a friend. He didn't give me any discs. It worked fine until I installed AOL. Then it slowed down, giving me many error messages. "Cannot find web page", "Web pages doesn't exist", etc. another friend used it last week, I went to defrag the computer, got the message, "Cannot continue defragging, because it has too many errors. Go to "Help", and follow the directions to clear the errors.
I went to Start, Help but got another message that the file was empty.

 

aol is the pits......i wouldnt have it in my house never mind my comp.

have you tried defragging in safe mode?


welcome to T.S.G by the way

 

Run Scan Disc before Defrag.
