I just finished my build, and began updating drivers. I have tried to install Vega Graphics, but the system crashes. Keyboard and mouse become unresponsive, screen goes black or is filled with static. I was able to do a System Restore. This got it functional again, but I am still showing the Microsoft Basic Display Adapter as my only Display Adapter. I have used DDU before the install. I believe Graphics are the only thing left for me to update.
AMD Ryzen 5 2400g
ASRock Fatal1ty X470
ADATA-XPG GAMMIX D10 16GB (2X8GB) DDR4-2666
SanDisk-SSD Plus 240GB SSD
Seagate-Barracuda 2TB 7200RPM
EVGA-BQ 500W 870+Bronze Semi-Modular ATX
Fractal Design-Focus G Mini
Windows 10 x64 Home Version 1803
Don't need to uninstall the windows basic driver, download/save the amd driver > disable/unplug router/ip device > install amd driver > restart > reconnect ip.
I did a clean install, updated all of my drivers, and still got the issue. Because the RAM I had in my build (ADATA-XPG GAMMIX D10 16GB (2X8GB) DDR4-2666) was still returnable I picked up some G.Skill TridentZ (2X8GB) DDR4-3200 (F4-3200C16D-16GTZB) to try it out. Sure enough, after I put the new RAM in the system kicked right up. I was able to use the XMP settings, and it is sitting stable at 3200. I did have to go back to a Restore Point before the AMD Chipset and VEGA drivers were installed before I put in the new RAM. I then downloaded and ran the installers. Hope this helps. Took me a week and a half to get it up and running.
