I swapped my old GPU on my PC with a GTX 970 and everything worked fine for the first few minutes. I started to install the new drivers and during the installation, my PC screen flashed black. There is a "ENG" flashing on the bottom right side of the screen which is likely indicating my keyboard input. There is also the Ethernet symbol on the bottom right side of the screen, showing I was plugged in using Ethernet. These two symbols are the only things displayed on the black screen and they appear and disappear about every second. I switched off the computer and boot it up again, and after the "HP" sign loads, the same thing described earlier happened. I removed new video card and put in my old one, and it works perfectly. My PSU is a Corsair AX760i. I won't be using this GTX 970 on my current PC as I will put it on a upcoming build. I just want to make sure the new video card does not have any hardware issues.
