I recently received an hp d530 desktop. When I turn it on nothing seems to happen. All the fans spin, hard drive spins, lights on front of pc are on, motherboard led on but no error beeps or any video. I did a little searching and found that a possible cause could be the motherboard. I had bought a replacement but the same problem occurs. The ram is brand new. Any ideas. Is it possible that the second motherboard is not working. I only have one agp video card so I can't replace it with another. Although the one that I use I pulled from a working pc. Any ideas?
