So the story that I got that one day she went to use her computer and nothing turned on ex. screen. So I have it trying to figure out why its not posting or booting up. I have check the hard drive with one of my other computers and it boots up no problem. I don't get any error beeps, it won't even bootup to bios. Everything on the computer turns on like lights, fans and stays on but it wont display anything. I have tried different screens, ports, took out her graphics card, changed the cmos battery but now I'm at a lost on what to do. Any help will be appreciated.
