I have an old P120 sitting around that i never use, and i was messing around inside to take out a NIC and cdrom drive. when i was putting it back together i managed to drop a screw on the mobo. (ive done this before without problems). When i went to start the computer up to make sure it worked all i got was the fans came on, the other cdrom has power, but the hard drives are not turning on and the hard drive light is staying on. nothing esle happens. i tried messing around with the power cables to no avail. did i fry the mobo?? not a big deal if i did, just curious though.
