Hello,
This is regarding the issue I am facing with the new Ryzen 5 2400G APU
I have been trying to figure out a solution for the flicking screen and the Blue screen of death from the day of purchase (04/04/2018) yet i couldn't find a proper solution.
1. First I didn't know I need a previous gen processor so that I can update my BIOS to F22 (Gigabyte AB-350 Gaming 3). Then I happened to take to the gigabyte service team and got it fixed.
2.Once I'm back home I've installed windows and visited the Gigabyte web page and downloaded the latest drivers available. and soon after I've the instillation of Radeon graphic driver/Display drivers (Express install method) the screen started to flicker then stuck on solid colors (green,blue & Gray) later it keeps boot looping and then the start up screen of windows says "Analyzing issue" the only solution at that movement is I restore my windows (clean install again) which is no use.

3. Then I was asked to visit this web page (https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-for-Ryzen-Desktop-Processors-with-Ra...) where i had to manually select my processor and then download the drivers, which still didn't work.
4. Later on by the help of Online/Customer Forums and You tubers I was told to first install the chipset drivers and then to install the graphic drivers (Custom install method) and was told to do some tweaking in the BIOS to the chip set performance.

5. After doing that it was fine for awhile (2-3 Hours) then my screen freezes and ends up at a BLUE SCREEN WITH A STOP CODE:VIDEO TDR FAILURE. I have tried checking with different connectors and cables (HDMI/VGA) even a different Monitor.

Not sure if its the Motherboard issue or the Processor's/Ram..!!! i have tried everything reinstalling display drivers/Windows and even checking my ram stick with other slots on my motherboard. 
I Still get the BSOD.
PLEASE HELP
