First of all I'm not a noob and have never had as many problems with something PC related until now:-
I have been having a long term issue with resizable BAR not being active and pretty much gave up on it until checking EVEN MORE requirements(GPT etc) recently. I Have a 5800x and a 6900xt so I more than meet the hardware requirements. I have checked bios settings, windows settings, UEFI settings and no matter what I try it will not work in windows. I've updated my BIOS; which means I have to reset my CMOS(thanks MSI...) but no matter what I try windows will not recognise that I have everything enabled;
Before anyone says anything...It IS enabled in the bios, I have no idea why it says it isn't.
