Hi
(sorry for the poor english, it is not my native language)
I had a vega 56 one month ago but it died, so, i replaced it by a RX 5700 yesterday ,i currently use a Nvidia gt 730 to use my computer.
So the first time i put my rx 5700 in i used HDMI, my computer starts, i see the bios: no problem, i see the windows icon: no problem, then when it load my desktop after 2 second on desktop "no signal", i tried to restart many time but every time it's the same problem.
In that state i can run windows through safe mode, i used amd cleanup utility and ddu to uninstall all the drivers, then when i tried to install the drivers for rx 5700 i had 2 error:
https://www.amd.com/fr/support/kb/faq/gpu-kb1603 this error never came back
https://www.amd.com/fr/support/kb/faq/gpu-kb99 I disabled the control for "digital signature" and never see it again too
So i could install the drivers for rx5700 but when the drivers are installed, "no signal" issues came back.
I tried to:
-Clear Cmos
-Reset Ram
-Update Bios
-Disable FreSync
-Tried many version of drivers for this card
-Used another windows version and another SSD (same problem)
-Tried the 2 PCIe x16 3.0 i have
-Test my PSU 8pins (everything is fine ~12v per pins)
-I tried the BIOS "Boost" and "Silent" on the card
-I tried to use other GPU (and they works, i'm curently using a little gpu Nvidia GT730) to run my pc)
Facts:
-I cannot try DP
-My GPU is listed in my device list (in windows safe mode)
-Fan don't run and my Gpu heats
-Power suply Led on GPU Are both "ok" (blue)
