GPU Driver Crashing at random times

[T3B]

Hello!
I have just connected a second screen to my PC, and it had to go into the integrated gpu port since the graphics card doesn't have a VGA connector. I didn't have high hopes for this to work, but it did and I can use both the GPU and the iGPU. I have, however, encountered an error.. At times when I, for example, start a video or launch a program, the GPU driver crashes and the main display turns into blue and black vertical lines. The computer is still functional and I can use the screen connected to the iGPU, but I have to reboot to be able to use my main screen. The crash, other than how I described, comes at completely random times, and unlike a regular driver crash, it isn't fixed by restoring the driver. I have checked the windows logs and it confirms that the amd driver crashed and was restored. Is there any way I can solve this?

Edit: I do have the latest drivers on both graphics cards

If GPU has a DVI-I or DVI-d outputs you can use a DVI to VGA adapter. Anything like those: DVI to VGA Cables : Cables & Connectors - Walmart.com and that be able to use discrete GPU exclusively.

Sadly I don't have any more DVI ports available, the only free ones are HDMI and DP's. Though where I live, adapters for those are too expensive for me to buy...
