Wow, thanks for all the inquiries. Sorry about the lack of info in the original post, but I didn’t realize the full extent of the situation myself until my younger brother reached home, and told me what happened. Here it is (at least, to the best of my understanding): There was attempt to change the background color of the windows xp login screen, according to the instructions at this website.
http://windowsxp.mvps.org/logonbg.htm .
A REG file was made to provide back up of the file HKEY_USERS\.DEFAULT\Control Panel\Colors (and saved in my pictures), and then the original digits (not the numbers on the backup file) were edited to a new color scheme. Then, I guess he switched user to see if the color scheme worked. But instead, it merely brought him to blank screen with no way to log back in. Now, when the computer is turned on, it loads the windows logo screen, but then goes straight to the blank, black login screen. So there is no presentation of the option to press f8 or anything. Also, prior to the manual change of the login color scheme, a program called login loader was installed. After waiting a few minutes on the blank login screen, it will come up and ask which login screen I would like to implement. However, there are no other schemes available on this computer, so I can not pick another logon screen. It provides me with the option of using the default login screen, which I take but it doesn’t work. Somehow, it seems as if a blank, black screen has now become my default user screen.
I am at a total loss of what to do. Without f8 (because those options don’t come up now, it just loads and then goes to the blank login screen), is there anyway to get back into the pc, or is the computer virtually destroyed, or can it be repaired in a shop? Any insight would be helpful, and thank you X 1000 to anyone with suggestions! And I apologize for the incoreect thread title! That was ignorance on my part.
