So I'm fixing a friend's mediacenter PC who's motherboard crapped out. I buy him a new mobo of the same type, and I install it without any real issues. Except the front panel connectors are in one of those thick black things that keeps them all together so they can all be plugged into the mobo at once. Well that black thing was built for the other mobo, and the pins don't line up right, so I pull the pins out of the "pin holder" thing and go to plug them in individually.
Here's the weird part. I plugged them into the on/off pins on the motherboard, but nothing happens. I tried switching which pins they were connected to, nothing happens.
However, I accidentally brushed the pins on the mobo with the wires for the power button and the fans turned on (making a lot of noise, actually now that I think about it.) I didn't plug the monitor in to see if everything was actualy running, but I think it was.
Can anyone figure out what kind of issue that is? Or where I should go to find out?
It's a Biostar A780L, if that makes a difference. Thanks for your help folks!
