I have an issue with my R9 Fury X.
It no longer works at all. The Radeon logo lights up, and the fan spins, but the LED power lights do not work, and there is no video output. I have swapped cables, checked the monitor and updated the MB bios, but still nothing. I had just updated to the latest Radeon software, and everything was fine for a few hours, but then the screen just went blank.
