Ok this a problem that I had long time ago and by that time I solved reinstalling Windows XP from scratch, but now is back and I have too many things so if there is a quicker solution withou loosing all the configs and have to reinstall again it should be great.
Mainly the problem is at My Computer/Explorer mouse right click opens a menu, right? On that menu there is the "Format" option so if I click on that option I get nothing, no new windows with the format options, no error, no nothing and this for any fixed HDD or USB Pen drive letter on the main window (My Computer/explorer).
Also trying to format trough computer Management I get this error:
"An unexpected error has occurred. Check the system event log for more information on the error. Close the Disk Management console, them restart Disk Management or restart the computer."
and the event log says this:
Event Type: Error
Event Source: LDM
Event Category: None
Event ID: 2
Time: 10:21:11 PM
Unspecified error (80004005).

So I hope someone could help me here, thanks.
