I have recently purchased a gtx 770 for my computer, replacing my old 650. When I went to install it, all I did was switch the cards, I did nothing with drivers or bios. When I plugged my computer in, absolutely nothing happened. I talked to nvidia employees, but all I learned was that I needed to update my motherboard. I reset the Bios (by taking the battery and RAM out) but now when I tried to update, and put the 770 back in, once again nothing happened. I tried reseting it again but it didn't work with the 650 like it did last time. I have no idea what's going on with my computer, I have drivers for both cards, and Msi live update 5 didn't work. My motherboard is an Msi 970A-G43. I would love help on what steps to take to get my computer running again, and sorry for the length of this question.
