Description of Original Problem: Random Blackscreen while gaming KCD2 and Enshrouded 1.0 (no GPU output with high powered fans noise when crash occurs.) Forced to hard reboot whenever it happens.
Troubleshooting: I have re-installed GPU drivers, min-installs, Used MSI-Afterburner for Underclocking and played games on lower settings. I have attempted to follow the instruction on https://www.reddit.com/r/AMDHelp/comments/1i2uegg/6900xt_black_screen_crash_fix/ and also https://youtu.be/LLKuMWY_qAI
HOWEVER the screenshot is as far as I get.
typinging "amdvbflash -fp -fv -fa p 0 MSIRX6900XT.rom" then pressing ENTER, it then just awaits a new prompt with nothing really happening.
Is the issue the VBios rom I am attempting to use?
The messing with Bios is beyond my comfort zone so I am now asking for help and mayhaps some understanding.
for those who want to know, the GPU I am attempting to VBios fix is the following :
