I have a Compaq Presario PC (bought it the beginning of 2005.) Yesterday, it crashed. It started out with the monitor cable not reading the hard drive, so we unplugged everything and replugged it, thinking that it would fix it. When I plugged it back in and turned it on, the hard drive decided that it can't get enough power to start. It tries to start and fail. I can't tell if the monitor cable is working or not because the hard drive won't stay on.
One of my friends who is technically capable to handle most problems said that my motherboard is getting power, but that it can't maintain it. There are no visible jumpers and clearing the capacitors did not help at all.
I would really appreciate it if anyone could help.
