Recently I re-installed a clean version of Windows Vista Home Premium. I
have done all the updates and installed anti-virus software. Then I was
trying to run defrag and when it opens it says "Your file system performance
can be improved" at which point I click on "Defragment Now". At this point it
would say "analyzing disk" for 2 or 3 seconds and it then goes back to "Your
file system performance can be improved". I keep clicking on "Defragment Now"
over and over again but it keeps doing the same thing.

I then scheduled Error-Checking on the next start-up but when the computer
restarts, nothing happens. I've tried it a few times and the disk is never
scanned. Any help or suggestions will be appreciated.
