Hi, I'm now unable to logon to Windows Vista after a disruptive shutdown. Now, after the Vista loading screen, I only can see a black screen with a cursor in the middle. I'm not able to hear and see the Windows Vista startup sound and screen. I'm also not able to choose which account I wish to logon to. I think this is a quite common Vista problem as my friends also encountered this problem. Is there any solution to this problem other than reformatting my system? Thanks and really appreciate the help!
