So I upgraded from a GTX 660ti to a GTX 1660 recently, and have had no problems with my pc, but when I put in the new gpu the pc won't boot fully. I get an error that says b2 in the corner of a black screen. It will just stay like this until my monitor shuts off eventually. If I switch to the gtx 660 ti, everything works fine again. Any help making this new gpu work?
