Wxp sp2 defrag

How can i enable to defrag my hadisk when my pc is idle?
is possible to setup the idle time?

and is possibily to avoid the blue screen when xp is loading?

thanks

You should defrag and step away from your machine, cause if you use it, then defrag must start again.

You could try to get hold of Diskeeper or PerfectDisk. Both are much better than the standard one & don’t seem to be affected by occasional use. They can be scheduled to run at whatever time is best for you.

i play counterstrike while i defrag sometimes. it still works.
