Hi, Windows XP Home Edition The night previous I added a new user account and also turned off the Guest account in XP. I swapped between users just to check all is OK, logged off one and onto another also - everything fine. I shut down the PC I turn my PC on today and it gets as far as the Welcome - Starting up windows Screen - then just sits there - it hasn't crashed or anything - just sits there - no user accounts, logon screen etc. There is some disk activity and then nothing I can't even get past it by selecting all the other boot options - safe mode etc. So am blocked out of my PC and pulling my hair out ! Searched the Knowledgebase and have found nothing as yet :- ( Can anyone please help ? Has anyone seen this before ? I am an IT person - so technical explanations/solutions - plese fire away. Next step could be boot disk and meddling with the system files, but I haven't a clue which ones are relevant. Thanks, Scott (I have done this before some months back and then deleted the temp user - all was fine then) .
