Multiple AMD graphic cards cause Windows 10 to crash BSOD

Hello all,

Currently, I have a setup of 1 PC + 3 monitors. I’m using ASTER to create a virtual desktop to enable 2 users to simultaneously working on my PC.
Here is the setup

Graphic CardXFX HD 5770 1GB GDDR5
Monitor 1 (M1)Dell UltraSharp 24” Monitor: U2412M1920 x 1200 at 60 Hz
Monitor 2 (M2)Samsung SyncMaster P2350 23"1920 x 1080
Monitor 3 (M3)HP N270 27”1920 x 1080 at 60 Hz
Power SupplyCorsair 750W HX


Since graphic card can only generate output to 2 different display at a time, I link M1 and M2 using ATI Radeon Eyefinity.
So USER A will be using M1 and M2 (paired with Eyefinity), and USER B will be using M3.
But the problem with Eyefinity is that, it will force the lowest resolution of the paired monitor as the baseline, in which my M1 is force to use 1920 x 1080, which causes distortion in height.
I prefer M3 as a standalone monitor, since it has the largest dimension, so I can watch movies comfortably.

So I bought HD 5670 to be paired.
After hardware and driver installation, my Windows 10 crashed on boot up, got BSOD.
Then I did several testing to determine what cause the crash.

Here are what I have tested

Is there anything I can do to make it works?

Thank you very much.
