Hi All,
I just received a refurbed PC I purchased through UBID. The PC is an HP Media Center. Upon installation the PC worked fine for about 15 minutes then abruptly shut off. I attempted to restart with no success.
I noticed that each time I pushed the on/off button on the front of the tower, the power supply light would go off on the back of the tower. I removed the panel and checked all connected of the cables running from the power supply. All were securely plugged in.
I then unplugged the cables running from the power supply one by one and attempted to power up the PC. When I unplugged a cable indentified as P7 from the motherboard (this is a small plug with 4 wires) the power supply works fine. If this cable is connected, the power supply immediately quits.
Does this sound like a faulty motherboard, or possibly a faulty cable? What further diagnostics can I do to be sure?
Thanks,
Kee
