Defragger is an system software
The Diskeeper Defragmenter does, indeed, seem to play havoc with the inbuilt Windows Defragmenter. After removing the Diskeeper software, I managed to reinstall the Windows one by using the information I found on a computer forum. For more information, see the Related Link. (1) It's never a good idea to run 2 defragmenters, since they may conflict with one another, and cause problems by locking up files for exclusive use. Another problem is that one might undo the work of the other since newer versions have more advanced algorithms for defragging and file sequencing. (2) The windows XP defragger is a very basic version of an old Diskeeper edition from many years ago. It was licensed by Microsoft. When you install a new version of Diskeeper, it only disables the XP defragger, it does not uninstall it. There is absolutely no point in having both the advanced (Diskeeper) as well the basic (XP defragger) versions of the software running on the same machine. Also see pt (1). If you had problems with the in-built XP defragger after uninstalling Diskeeper, it is most likely due to an MMC error and probably related to XP Service Pack 3. I am a long time Diskeeper user, and have never had trouble with the XP defragger even after uninstalling Diskeeper (or any other software for that matter).
That would be the defragger.
If you run the built-in Windows defragger while using the computer, then the defragger will pretty much do nothing even if there are free system resources because it's resource utilization algorithms are not very good. Overall, the defrag will take a very long time. Combine this with the fact that the defragger doesn't even defrag all files properly, and the whole operation becomes a waste of time.However, third party defrag utilities, especially the advanced commercial utilities, that are specifically designed as automatic background defraggers have no such problems. They utilize the unused system resources effectively and calibrate their operation accordingly. So, you can use the computer yet get the defrag done in the background (but remember to disable the windows default defragger when using a third party utility).

Not if you have a good reliable automatic defragger that runs in the background. Once you set it to defrag automatically you really never need to bother about defrag.
Go to "My Computer" in the My Computer folder right click the hard drive and then go to properties. Under properties click the "Tools" Tab, and then click "Defragment Now". Also note that for running the Windows defragger you need to have atleast 15% free space and preferably turn off other programs that are running otherwise it tends to hand midway. It also does not defrag system files, for that you need to download a third party defragger.
If you mean the PC powered off, no it does not. If you want to defrag without having to set aside dedicated time, install an automatic defragger that runs in the background while the PC is on and defrags with the idle resources.
