Hi everyone, I recently bought a 980m graphics card for my M17xR4 as my old 970m developed problems. I fitted it to the heatsink and it seemed to fit ok, but on starting the laptop I get 8 beeps. Is this simply the wrong graphics card for the laptop or is likely another issue? The card doesn't seem to have the usual x-shaped plate on the back like my last one and instead has a copper backplate (image url inserted below). https://imgur.com/a/lh7JkFS Thanks in advance
