I have a Lenovo G40-80 notebook, it has a 2GB AMD R5 M230 video card, after I changed the sdd and installed windows, I no longer recognize the video card, I used the video card drive itself, more talk there is no video card, and before changing the ssd worked perfectly.
1. R5 M230 is GCN
so download latest driver from AMD website
if this fails go to Lenovos support website and download the driver provided for your laptop!
2. maybe you have damaged your GPU while you changed your SSD
already downloaded the latest drivers from amd, as well as at Lenovo, it doesn't work. good the gpu is not close to the ssd it only has a cover and easy access for exchange.
maybe reinstall windows again
