MOBO: ASrock A320M-DVS R3.0
BIOS: Latest (Agesa 6)
CPU: Ryzen 5 2400G
RAM: 1x4Gb 2400Mhz CL17 + 1x8Gb 2666Mhz CL19 (8Gb stick in slot 2)
Display adapter: D-Sub (VGA) (1366x768 monitor)
If You are not updated BIOS, You MUST install the pre-update drivers "Allin1(v18.10.20_NHDA" - (my motherboard - ASrock A320M-DVS R3.0)
READ THIS FIRST ! Worked for me, I'm not guaranteed that it will work for everyone. This worked for me and I wasted about 8 hours looking for solutions when it was the Before-BIOS update drivers that fixed the problem. Next problem was incorrect resolutions, fixed it with unplugging cable from monitor and PC and connecting back. (Used old cable which came with monitor).
If the latest drivers keep crashing, go to Safe Mode with Networking and run "amdcleanuputility-x64"
Then go back in to Windows 10 and install pre-BIOS UPDATE drivers. ((Allin1(v18.10.20_NHDA) for me, depends on motherboard.) Latest motherboard drivers I use right now "AllIn1(v19.10.08_19H1_WHQL)"
Latest AMD SOFTWARE installed "win10-64bit-radeon-software-adrenalin-2019-edition-19.5.2-june3"
Before BIOS Update install recommended motherboard drivers. (If BIOS already updated, download recent drivers needed before the BIOS update).
Check RAM compatibility (Should be good if using Dual channel with same timing in BIOS (4gb 2400Mhz and 4gb 2400mhz for example).
Check display resolutions ( I had a problem with incorrect resolutions, original monitor cable worked. Could be a case when re-connecting monitor to display (in my case D-Sub) will actually fix the problem.
If RAM is OK(frequency and compatibility), BIOS updated with recommended drivers before update, try to install latest drivers.
Hope this will work for You.
