I am trying to help a friend fix his computer. He believed is mech HD died. I booted it and I can't get to the BIOS. When I boot it only shows a "HP" logo and will not continue to any kinda of boot state. I have tried, del, f11, f2, f12, and every combo. I just cant get to BIOS. I re-seated RAM. I have remove and reinstalled the battery.I have tested another power supply. I have the windows boot CD in the optical drive. However every time I boot it goes to a "HP" screen shot and will not continue and there is no option for BIOS. Any help would be greatly welcome. Thanks
