I am replacing my GEFORCE GTX 460 graphics card with a Nvidia 2000K. Doing this so I get full 10-bit on my Dell U2410 monitors. My mobo is an MSI Z68A-GD65 G3. Windows 10. I have taken out the GTX 460 and inserted the 2000K in the same (first) slot. When booting up the codes in the bottom right of my monitor initially show B4 and then B2 and stays that way without anything else happening. Not sure if I need to update BIOS etc., if I do how can I do that unless I can get access to Windows?
