I ended up buying that exact board last night actually
It was the same price for a replacement M4N82 which was only a refurbished board with a two week guarantee, as it was for a new M4N98TD EVO and 4 GB of RAM, ridiculous!. Plus the DDR3 1333 should be a bit better performance wise too. I had DDR2 1066.
I hope it was the board that was actually knackered though. I think it was but then I thought it was the SSD the last time and ended up buying a new one of those and another Windows 7 which is a bit of a bummer. I will make a little media centre out of all my spare parts though so it's not too bad. I suppose I will have to just keep replacing parts until I get to the bit that's actually broken!.
