VEAI GPU processing unrecoverable black screen when start processing, even when doing previews

Whenever I use my GPU to process the video, even for previews, my monitor will just turn black. and I cannot do anything to recover from it other than hard rebooting my pc.

I tried different models and reducing the GPU RAM usage all to no avail.

GPU: Radeon ™ RX 480 Graphics
CPU: Intel® Core™ i7-6700K CPU
Memory: 16384MB RAM

Any help?
