Hi, I have been having an issue with the login screen on my computer. After pressing to remove the picture image the screen in which the password box would normally appear does not display. This prevents me from logging onto the computer and essentially leaves me locked out. I have not been able to boot in safe mode as for whatever reason it is being unfavourable however I have managed to perform a system restore to a time prior to the issue however that has not solved it. Any help would be greatly appreciated.
