Hi recently i was playing roblox on my pc (not a very high performance game) and my pc ended up freezing and then just shutting off, i have two monitors and when it came back on only one turned on now which ever one turns on it’s super low quality. and i can’t change the refresh rate, when i went to AMD to diagnostic my 6750xt it says that its the wrong version and wont open. I’ve reset the cmos battery, taken out the ram and put it back in, taken out my graphics card and put it back in and nothing seems to be working can anyone help me with this please?
