I have a Dell Inspiron 5150 that doesn't seem to post. When I turn it on, the power light comes on, the battery light comes on, I hear the heat sink fan run, but I don't get the Dell splash screen. I tried a different video card. Nothing. I connected to an external monitor. Nothing. I have heard of a lot of problems with this model, but never about the video socket on the motherboard. Is there anything else I could try?

My HP Pavilion dv9700 was over heating and would shut off. Then it wasn't over heating and would shut off. Now it won't turn on at all. The power cord is working and the lights go on for a second while I am pushing the button to turn it on, but the computer won't turn on. HP told me the problem was the motherboard. Do you think that's really the problem or could it be something else?
