So I have a maximus V gene and I first got the b2 error and it would not post so i sent it in for the warranty, It came back and I put it back in the case a plugged everything back in and I get the same error when I have my gpu in and when i dont i get the d7 error. I'm going to send it back in again if I can but I would like to know if there is anything else I can do beforehand. I've unplugged all of the hard drives and there is only one ram stick in and no gpu.
my specs are
maximus V gene
gtx 660 ti
8 gb corsair vengeance ram
thanks
