Hello everyone!
I'm new so I hope I don't make the typical trivial mistakes of newbies.

The problem is that the network stops working (the leds turn off) when I have two graphic cards are installed.
The card turns off after the initial blue screen so I don't think it's a PC problem.

Any advice?
Feel free to ask me what other information may be useful.

blue screen? can you explain?

if the leds turn off it might be a hardware issue. maybe two graphics card use too much power?
 
what do you see in dmesg, /var/log/syslog and journalctl when the network interfaces go down?

I had the opportunity to reinstall proxmox with the two cards already installed and it works.

I checked and the interface changed its name (from enp4s0 to enp5s0).

I tried again and in fact it was enough to change the interface number in the configuration file /etc/network/interfaces .
