Until today, My PC ran a Sapphire R9 380 Nitro, which always displayed perfectly. Today, I added a GT 720 to the system just for the fun of it and to Mine Crypto while I use my main card (The 380) for everything else. However, now when I start up my PC, I see the Bios screen like normal, but then the monitor says "No Signal" and the Only way to get the signal recognized is to unplug the DVI cable from the Monitor and Plug it back in. Any suggestions? Thanks in advance!
