Re: a7v600-x stuck in reboot loop?

I forgot to say that I think this is a motherboard defect. I have seen
similar problems with this board(A7V600-X) at ASUS support forum website. I
would RMA the board but I'm afraid I'd just end up with a problem similar to
this on the new board they send me. Greg T
P.S. I don't think I'll be buying another ASUS board again.
