Defrag doesn't run

[catilley1092]

yes, my computer is only about 6 mos. old and I haven't loaded too much on it

You need to call the OEM of this computer and let them know about this. Today, your defrag program isn't working. What will it be tomorrow that doesn't work? A six month old computer shouldn't be having these problems. You can (and should) reinstall your OS and see what happens. If this doesn't fix it, you may have corrupt software, and your OEM is responsible for making it right.
