Where I live it's pretty much Newegg or nothing xD. When I ordered the MOBO it was two months before I actually built my PC and it just so happened the day I built my PC and found out the MOBO was missing some CPU socket pins, it was the day after the return policy ended.
I threatened to go to the BBB on them and they replaced it, after saying that they wouldn't at first. But I mentioned the fact that they were caught recently shipping damaged MOBO's so I think that changed their mind.
It's really odd though yours had problem if it didn't with your partners PC. But what can we do? It's life, eh?
