I have a MSI r9 390x and yesterday I began receiving a black screen and a no signal message on my monitor. I reboot the pc and it will work for a while but continues to do this. Sometimes when I reboot the PC after losing my monitors it will power up for a second and then shut down immediately, it will repeat this over and over until I switch of the PSU and start it again. I have reformatted, tried several different drivers including the latest and going back to the catalyst 15.7 driver but it continues. It began yesterday while playing Dark Souls 3 but now does this while out of the game, sometimes it happens immediately after rebooting.
What do I do?
