When I bent a few pins on my Z77 board I contacted Gigabyte and the arranged to collect it for free, repair the board and then ship it back out to me for no charge. I can't say that would apply for every situation but it just gave me another reminder as to why I prefer to deal with Gigabyte. Having a UK returns dept. is useful.
I don't tend to buy Asus stuff but have you tried contacting them...? Not sure if they will be as helpful, or UK based, but worth a shot.
