New 9070 GPU but no display
Hope somebody can help me.
I recently bought a new 9070 to replace my old 5700XT.
B450m-a bios version 4645
5700x
750w PSU
After plugging it in, with both the displayport from GPU to monitor as well as HDMI to TV I had no display.
Changing back the old 5700XT and everything worked perfectly again. So I tried the 9070 a couple more times hoping for some suboptimal installation but no luck.
At this point I thought it was a GPU problem and replaced it with another 9070 from a different brand. However I have the exact same problem. When I boot up pc everything else seems to work just fine, but no display.
In theory it should work and after two failed 9070 attempts it would be extremely unlikely it happened to receive two faulty GPU's.
Changing drivers should not matter because I should atleast see some display even with bad drivers. Might be a bios thing but I don't want to randomly click buttons and mess up stuff.
Anyone has any idea what the problem might be? Appreciated.
