I have an MSI Z68A-G43 Motherboard and I'm trying to use a GTX 1070 on it. I'm currently using a GTX 670 with no problems. When I plug in the 1070 the motherboard does one long beep followed by two short beeps indicating a GPU problem. Do I need to replace my motherboard to use a 1070 or is there an easier solution? My PSU is 650w. I have not tested the card on another machine because I do not have one available.
