RX 5700 "no signal" when i download the drivers

Question asked by tonali on Nov 17, 2019


(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:  this error never came back 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) 


-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)
