since i built my pc i have been having the b2 error shown on my MAximus formula v 1155 Mobo. I had been able to correct it, but i disconnected my pc for about a month. when i plugged it back in the b2 error showed up again, but this time not even with the online solutions, i havent been able to correct it. I think it is my radeon hd 7970 since it doesnt work in any pcie slots. I have read that the power source may be the cause but my Cooler master silent pro 1000 w has OK reviews, but i dont think its that. any suggestions
