Good time of the day!
I have the following problem.
I bought a Saphire Radeon RX550, I wanted to replace my old GeForce GT 630 for the places. But here's the thing, the motherboard (Intel DP67BG) hangs on the BIOS splash screen, the monitor is connected via HDMI 2.0.
The question is what could be the problem?
A more recent firmware can not be found even on the office site
Incompatible card. It is very typical that AMD cards are not backward compatible with these older boards. Return the AMD card and get a refund, and reinstall the nvidia card (which are much more likely to work, especially the older nvidia cards).
