So I build my friend a computer recently with an MSI Micro ATX motherboard, and now it won't turn on. I stripped it down to just the 24 pin and 4 pin connectors hooked up. When the 4 pin connector is in, no power gets delivered. The moment I take out the 4pin and turn it on, the case fans will spin, and the board gets power. Tested with two different PSUs and had the same problem, even tried taking out and putting back in the battery to no avail. Is it a bad mobo?
