Hi there, I'm a noob so I don't know if I'm posting in the right place. I have a 3 yr old Lenovo Z61t, running XP. All original hardware. I'm getting a blue screen error at boot up. It shuts the computer down and restarts and it happens again. I've wiped the hard drive (thinking it was maybe a virus) and formatted it, and reinstalled windows, and still the same problem. Gotta be a hardware problem. Can anyone help? I've posted a picture of the blue screen.
