I have a older lenovo M81 prebuild system that I have upgraded (i7 2600 8 gb ddr3 120gb ssd 1tb hdd) and I have a new rx470. From all of my research they should work together in sort of a plug and play fashion, but when I plug in the gpu the system wont post. All other components of the system are know-good, as well as the gpu which I tested on my R5 1600x system with a b450 mobo. My bios age is set somewhere in 2011 and the lastest update was in 2014 I'm hoping that if I can update the bios with should work. I have no idea how to do that however I've down loaded the iso to a usb and tried booting from it with no success. Send Halp please😅😭
