Could you RMA the motherboard? I was able (pending) to RMA two EPoX boards which were under 3 years old by a few days. Of course, they had leaking caps, so EPoX should feel compelled to replace them.

It's the cheapest solution and avoids having to reinstall all of your software. That is, if you can be without a machine for a while. Unless AOpen does "advance RMA" where they send you a replacement board first....
