I had a Gigabyte GA M61SME S2 ( el cheapo nforce 6100 AMD board) which refused to boot recently.
Sent it for RMA, and got it back after a month ( more actually, board was given to dealer on 28/09.
Its a refurbished board, and the onboard was not working. Now I have to wait another whole month. The dude at the dealer ( have known him for some time now, has promised to call up Accel , and follow up, but I'm a bit disappointed. I had been a long time ASUS fan, and had switched to gigabyte after hearing about the various ASUS issues, and Having my own not so good experience with an M2A VM.

I'll update this thread as the RMA progresses, but has anyone else been facing this issue ?
