Vista - Windows Vista Check Disk & Disk Defragmenter

Hello Vista Forums, I was thinking to make my computer faster and lose some space, so i went ahead and did a Error-checking and got the Vista Permission thing and continued and i checked Automatic fix file system errors and scan for and attempt recovery of bad sectors then pressed start and nothing happen , i ran Check Disk with admin cmd and works. I rebooted my computer to see if chkdsk works and its not theen tried to do the error-checking and still doesnt work. Then when i tried to use my Disk Defragmenter , i waited till the analysis finished then i got the thing that said your file performance can be improved, defrag now. And i clicked which disk i want to defrag and press ok , nothing happened and juss went back to analysis then your file performance can be improved, defrag now. btw i tried to use Defraggler and ran as a admin when i click analyze, nothing happens and i looked at the status and says Analysis failed, i even tried juss going defrag and the status said building file list failed.
