I was trying to fix my elderly father's Compaq SR5710F this weekend. It worked perfectly for 2 years and all of a sudden it gets stuck at the Compaq logo screen with a falling man (upside down man standing on one hand) next to the logo. There were no hardware modifications or new software installed. I tried F10, F11 but nothing worked. I replaced the CMOS battery and now it will sometimes start up to Window Vista, but the next time it gets stuck again. I searched but cannot find any reference to the falling man. Any help would be greatly appreciated.
