I have bought a few motherboards off of eBay to build a new system. When the motherboards came in neither system would post. I tried 2 different cpus, 2 sticks of ram, 2 power supplies, 3 motherboards, onboard graphics and dedicated video card. The cpu fan ramps up like normal for a few seconds and the systems reboots itself. The 2nd boot it's stays running but no display. Any other options i could try?
