Question Working pc, but no display

[smarkoc]

Hello everyone,

Yesterday I upgraded my PC, then I wanted to turn it on to finally play games, and I got no display on my monitor. I went from an R5 2600x to R7 5800x3D, 1650>3070 and 16GB RAM>32GB RAM. By the way, I have a 650w PSU. all lights, and fans just turn on, so everything should work. The R7 5800x3D does not have integrated graphics, so unfortunately I cannot try it without a video card. b450m s2h motherboard.

I have already tried the following:
- put in the old CPU, GPU and RAM and then tried it
-ram sticks, and try to clean the ram ports
-tried a new cable and an HDMI instead of display port
-tried on another monitor (TV).
-CMOS reset
-checked all cables

personally I think the problem lies with the connection between the motherboard and GPU, but I cannot check this, maybe that port is broken.
I also scrolled through the internet and YouTube, but couldn't find anything useful, so I think it would be wise to ask help from people who know more about it. Thank you in advance, and i look forward to your feedback

Update your post to include full system hardware specs and OS information.

Make and model motherboard?

Some motherboards require that the first physically installed RAM be placed in a specific slot.

Are you able to connect to another known working monitor?

Are you able to connect your monitor to another known working computer?

Determine if the problem stays with your computer or follows the monitor.
