text: defragging my computer? my computer wont defrag. it goes into "check drive for errors" then after 5 minutes i get a window that says it has tried to defrag 10 times but the windows system is busy. how do i change this situation? i successfully defragged the computer when i first got it but it suddenly starting doing this. i'm lost and its been a long time since it was last defragged. please help. i'm not real bright with computers so any help needs to be at the novice level. thanks. i am thinking you are a win 98 user, if you reboot into safe mode, then defrag, then it will run just fine.
