I am running XP PRO SP3 on an HP desktop.
Whenever I click on a .pdf or .avi file I get a box that says "windows cannot open this file" When I try to defrag y hard drive I get the same error

I'd try running chkdsk /r to overcome/check for file corruption.

You can also go to the file extensions mentioned...and check to see what programs are selected to open those files.

Explorer view/My Computer/Tools/Folder Options/File Types.

That worked for the .avi and the .pdf files, but I still can't defrad a hard drive. The system defrag comand is a .msc file. I can run a disk cleanup, but not a defrag

You should always run the chkdsk /r command...before defragging, IMO.

Have you done that?

Tell me the exact sequence of events on your failed defrag efforts, please.

Yes I ran chkdsk first. I go into programs accessories system tools and click on defrag. I then get a box that says "Windows cannot open this file DFRG.MSC

See http://answers.microsoft.com/en-us/windows/forum/windows_xp-performance/disk-defrag-cannot-open-a-filesystem32dfrgmsc-to/85c576d7-3323-4e1e-9d28-1a9afaa6c50e .

I'd reinstall SP3, http://www.microsoft.com/en-us/download/details.aspx?id=24 , click the Download button, save to your desktop, reinstall from there.
