I just bought a new graphics card for my computer today. I went online to AMD and found the proper installation drivers for it and downloaded it. When i go to the device manager to see the graphics card it says in the general tab "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
