I am getting this problem on an XP Home edition of Windows. I have checked on Microsoft and can only find an article for Windows 2000.
The computer has been built for a while and has only recently started, and is giving the 0x4E stop error (I really hate this error!!) It is only occuring infrequently (say once a month) and I'm fairly sure it's not hardware related.
If any help could be given as to the cause I would be very grateful.
