Hello, bought sapphire nitro + rx 470 4gb 10 days ago, still haven't been able to make it work. I waited a week for it to be inspected by the merchant that sold it to me and I am getting it back tomorrow. On their test bench with a pentium processor, h170 mb and win 10 install - the card worked.
My system is
Msi h110 pro-d
ddr4 2133 8gb kingson
crucial bx200 ssd 240gb
sg 1tb baracuda
xfx 430w 80+ bronze
windows 10 pro
Before I sent the card back, I removed the drivers using ddu, installed them from the provided disk - the moment I boot up the system with the card and it turns off to adjust the resolution - it does not turn back on "no signal detected" as if I don't have the card connected to the monitor, I checked many times - it is connected. I tried doing the same only using the latest drivers - same story. My old radeon 7770 woks just fine when I put it in. This is just infuriating.
The only difference I could see through a lot of reading and scratching my head the past few days is that my boot up is legacy, not UEFI. The merchant suggested I do a fresh install with UEFI boot.
I think I will ask for my money back if that does not work thou.
Any suggestions or some easy fix that I am missing ?
