Okay guys... update!
I spoke to my friend and he said that he didn't sell me the motherboard, but he will help me if I can get the serial numbers.
Anyways, I dreaded making the phone call, but I did, the guy was cocky from get go... but I told him, look, I just need the serial numbers so I can find out (or try) warranty information for him - phone goes quiet.
Then he tell me, look, he is chatting to a guy from Intel at the moment whose name is Otto, he says the motherboard is still under warranty.
I tell the guy, look, even so, give me the serial numbers so I can do my bit and find out the information for him - he tells me, that I should leave it, because its packaged away, to get it would be a mission for him.
Then he perks up that Intel will swop it out and if he finds the time, he'll SMS me the serial number etc.
So in a sense, the problem is sorted... but now I'm wondering about this entire thing...
