Starting DF freezes system

Okay so I've been using CCleaner, Speecy, Defraggler I installed nforce and GFX card latest drivers and after restarting whenever I run Defraggler it freezes up my system not even the window opens. I have re-installed it 3-4times and restarted many times but its of no use. Its only happening in Defraggler, CCleaner is working fine.

P.S. i used two registry tweaks but not related to Defraggler.

FIRST:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvata

DWORD: DisableRemovable=1

SECOND:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\CDRom

DWORD:AutoRun=1

THANKS!

Perhaps you could try running Defraggler in debug mode to see if it can get any info for the devs.

Just attach the log in a post

I don't know how to put it, but i was defraging my WINDOWS drive and when it froze the last time, i restarted and then my whole windows partition is gone, i've re-installed XP and still installing drivers and stuff.

Now defraggler is working, LOL.

Don't computers just make you want to scream :)
