I upgraded from an old ASUS gpu to a Power Color RX6600 early last December. Everything was working fine until a few days ago. I had shut down the prior evening with no problems. The following morning, "No HDMI signal from device" displayed on my monitor. I checked cables, the monitor, reseated the card and the memory with no results. I then put in my old card and got the same message on my monitor. Has my old MSI board bit the dust? Any insight would be much appreciated.
