Hi I have a media center PC and I am unable to start it up. I press the button to turn it on and it shows nothing on screen. What can I do? I noticed that the processor on the media center PC actually fell out. So I put it back in. I can tell that the processor works because now that it is in properly I can turn it off by pressing the button. I can't figure out how to make my computer send some sort of data to my monitor so I can see whats going wrong. I think I may need to replace the motherboard, but all the lights work and fans work. I thought I needed a new processor, but it works. Then I thought I need a new AGP card. I tried that, nothing will output to a monitor, always get the "No Input" Message on my monitor. I know the monitor works because I am using it right now. So Please help me out with this issue Thanks!
