Hello all willing to help me out. Recently, my computer's power supply died out and took the motherboard with it. Unfortunately I didn't see the warning posted here in time. I replaced the power supply and found a cheap replacement motherboard kit type of thing on ebay that was compatible with my model. I plugged everything in and tried to boot it up, but when I press the power button I get nothing on the monitor. I hear the machine boot up like it normally would including the fans but yet nothing is on the monitor. The monitor just stays on the self test screen and shows nothing else. I'll answer any questions I can about the system specs, motherboard, or anything. Any ideas on what the problem could be?
