If it's possible to sue anybody for anything, you can do it in the USA. ASUS is based in Taiwan so a lawsuit would be awkward and you'd never win, because ASUS would send 8 high priced super-lawyers and you'd have 1 alcoholic depressed lawyer with a ripped jacket.
Also, why sue over a $60-$400 (avg 150) product like a motherboard? It'll cost you more to sue than buy a new motherboard. And if you sue, you'll lose. So why bother? It's just "the man" stepping on the little guy once again. It happens every day. We are fools to think that we, with our twigs and stones, can bring down the 1000 foot giants who tread on us.
