No display out on the ZOTAC RTX 3080

When we put the GPU on the motherboard, it has this buzzing sound from the motherboard speaker and has no display even when we connect the HDMI to the motherboard. Then when we took out the GPU, the buzzing sound is gone from the speaker and there is a display. Still does it even though we put it back. Any solutions to this?

Yeah we connected the HDMI and it has no display. We used a TUF Gaming B450M Plus, and I just connected a motherboard speaker on there. And for the CPU it's a AMD RYZEN 3 3200g.

If you connect a GPU, you need to connect the HDMI cable to the GPU, not the motherboard. What GPU are you trying to get running on that system?

I'm going to make the description more understandable for those who are reading. Basically we put a ZOTAC RTX 3080 on the computer, we connected the gpu using a HDMI cable to the monitor, and it had no display. We even switched the HDMI port to the motherboard which had a CPU with a IGPU while it was still on to see if it would have any display. And yet, after doing that, it still had no display. So then next we turned it off and took off the GPU to see if the IGPU had any display, and it did have a display.

Did you confirm that the PCI-e power connectors or plugged in? Is your PSU powerful enough for that card?

Is a 750W powerful enough? And yes, the PCI-E power connectors are plugged in.

you could try disabling the igpu in your bios and see if that makes a difference?
