Hi all , I bought a mb second hand and it arrived with 2 bent pins (board would not boot) , i decided to have a go at bending them back in place and they both broke off. I put it together outside the case to test, and all seems fine. rear usb , graphics slot etc. I hav´nt tested the front usb3 or usb2 and audio yet. I ran a couple of games no problem. my question is how do i know what those pins do , are there any tests I could run to check.
