In xp, if I open MY COMPUTER then right click on any drive letter, a SEND ERROR REPORT is generated and the screen is cleared off icons and taskbar.
After about 30 seconds, everything is restored, but the same problem occurrs repeatedly.
I tried a System Restore and file check but no luck.
Any advice wouldbe appreciated .

Get as much information as you
can about the error message.

Start>> Control Panel>> Administrative Tools>> Event
Viewer>> Application, Security, System (Doesn't hurt to
check them all)

Get your error codes and investigate! If you are online
at the time, double click the error code and follow
through for information related to that error code.
