This is my first post but indeed not the type of first post I wanted to make..
I am mining with 3 RX580 Nitro+ 8gb cards using claymore, all temperatures were <70degs
The cards were running default drivers, custom BIOS (mentioned here: https://www.youtube.com/watch?v=uiPCwJV_ryM)
Been using Sapphire Trixx to set Core to 1340, Mem to 2250, -96mV
Motherboard: ASUS Z270-P

All of a sudden the card was started hashing at 4.xx Mh..
I turned off the rig, disconnected the other two cards, connected HDMI to the card, rebooted..
Upon booting into windows, fans spin for 3 secs, screen flickers then turns to normal for 3 seconds.. REPEATS for 3-4 times.. then display stays on!
I removed the riser, installed GPU to motherboard directly, same thing happens..
I turned off the rig, connected HDMI to the MB directly, rebooted, removed all drivers using AMD clean uninstall utility and reinstalled the latest drivers.
The other two cards now work fine, fans spin upon turning the rig on, boot into windows, both cards recognized.
The stubborn card however, is not detected, no fans spin at any point of boot..
Not showing in device manager, not showing in AtiFlash, or GPU-Z..
I tried switching the BIOS switch on the card, rebooted, same thing.
The only indicators of life I have now are the LED's (turning on and going through the usual patten), the card is also warm to the touch in this state.
Is the card dead?
