For some strange reason when booting my computer it goes to a strange gray screen and stays there.
My computer is a Windows XP service Pack 2. And what happened yesterday is when I was Installing McAfee onto my computer it suddenly froze, but it said everything was installed and ready to go, but anyways I shut down my computer via the power button. When I turned my computer back on the usual "E-machines" brand thing appeared but then instead of it going to the Windows XP green loading bar screen, it went to a black screen, then a gray one, and now its just that gray one. I even left it on for hours and it just sat at the gray screen. I have no idea about what to do with it, so I'd love some asistance.
