When my computer starts booting up it makes it all the way to the XP black screen with the windows logo on it. Then it freezes the blue bar that usually moves under the windows logo doesn't show up and i'm left looking at it thinking, "Is it gonna do anything" I think it may be a virus or somw crap like that. I don't know why this keeps happening. My Zonealarm must not like me. I really don't want to reformat my hd and safe mode does the same thing freeze. Any help that can be offered would be much appreciated.
