I have an ASUS P6T motherboard, its just over 3 years old. It has been sat gathering dust since I upgraded to 1155 but last time I used it it stopped working and I noticed there was some burn damage on the back of the mobo close to the ram slots. I tried to send it off to the original retailer but they refused the RMA and pointed to the 'burn' damage. Since its 3 years old, would ASUS honour this rma? how long is thier warranty for?
