I cant successfully defraging my computer....

When i use Defraggler it always stops at 42%, when i use the defrag that's in vista it also never finishes...
When i use ultimate defrag it doesnt even start...

Any idea on what to do?..

Do you defrag in safe mode?

no am i suppose to defrag in safe mode?

try killing unnecessary processes, don't run other programs while defragging. Just a couple thoughts.

I use to have the same problem with my rig. Started running in safe mode when I went off to bed and had no problems. My thinking kinda goes along with what flareback says. Thought I might have had a process that kept stopping the defrag.

k ill see if it works.
