I did some checking, and the diagnostic LED code you list (amber, green, amber, amber) is an indication that it is running tests on the PCI bus. If the system is hanging at that point then something during PCI bus initialization is failing (PCI card, or motherboard). I would recommend pulling all PCI cards and checking to see if the problem goes away. If you are using a PCI video card in your system, try using a different (known good) card. If the problem goes away when the PCI cards are removed then most likely one of them is the problem. Since you are still getting a picture, I don't think it is the video card, but you might want to test with a different one anyway, just to be sure.
If you have other questions about the system, or troubleshooting the problem, I will be more than happy to help in any way I can.
