Broken power supply or mainboard when installing?

And it is so when I install a game and talk to others in Discord or Youtube / Twitch etc. Look everything that is connected to the mainboard releases USB and so.

Then I have to reconnect to the Internet and then it works again.

What could it be?

What do you mean it gives birth physically or digitally

Yes, all USB ports on the back are free of mouse keyboard, WLAN stick etc.

So if the power supply is broken, the power is gone so it must be the mainboard or the software may be the mainboard

OK thanks
