I recently purchased a second hand Sapphire Vega 64.
I installed it, installed the drivers and then the screen go white the picture would reappear. I tried playing a game( FAR CRY 5) and immediately the screen would go white and then normal again.
2 days ago the GPU just went black and then the Fan was loud like it was on full blast.
I restarted the PC and then there was no Signal and the fan has stopped all together.
Only Radeon on the GPU lit up.
The GPU was working 100% when it was tested.
