So I received a free 2009 Quad Mac Pro but it doesn't work. When I power it up the fans come on and I see a a few lights on the main board but nothing on the screen. Any ideas?
Got a tip for us?

You can open the case and hear if the hard drive is spinning up. It could be a video card issue or logic board issue. Also might want to check the video cable is inserted correctly or try a different cable and display.
I tired a new video card and cable but doesnt work. Could be the logic board. What components on the logic board could go bad? What can I check?
Thanks
If the logic board is buggered then your not going to fix it.
I'd take the CPU tray out and check all the pins are ok.
Reseat the RAM.
Download the 2009 Mac Pro Apple Repair Guide and follow it through?
I reseated the ram, cpu and checked all pins. I am hoping to get some help diagnosing to the component level as I have seen in some other threads here.
!?
At the component level you need other machines to test in.
If you mean electronic component level then I've never seen it, because it isn't possible!
Since it was a free machine. Not that it could happen, but can you check if the CPU is installed?
Third that. There is a set of diagnostic LEDs on 2009 backplane. I'd use these if all standard troubleshooting has failed.
