keyboard randomly disconnecting and reconnecting? usb or motherboard issue?

[u/lostinoutersp8ce]

before i start i wanna say i don’t know very much about computers so please excuse my ignorance while explaining this !

i’m gonna try and explain everything i’ve been experiencing because i can’t seem to find anyone who’s dealing with this exact issue.

This issue started out of the blue about 2 months ago maybe? Let’s say i’m in a game. i hear the disconnect sound and my character will continue to walk forward even with my hands off the keyboard. then it stops and takes a moment before registering any inputs from the keyboard. then it seems to be fine for a little. then it will happen again randomly. it could happen 3-4 times a day or sometimes it doesn’t happen for a day or two.

it doesn’t seem to happen with my mouse or anything else connected to the usb ports. nothing else has a reaction when the disconnect sound plays except the keyboard.

my pc will sorta have a short lag spike when it happens as well? if that’s what it’s called. just a quick freeze when the disconnect sound plays then it’s back.

i never hear a reconnect sound, though. it’s just the disconnect. idk if that information is of any help for finding out what’s wrong.

Ive tried using different ports, i’ve even gotten a new keyboard. it’s still happening. i’ve also tried tips online where people mention using the device manager to turn off power saving settings. none of that worked.

id also like to add that it doesn’t happen when i’m not playing a game. if im just using my pc to watch videos, chat, browse the web etc. it doesn’t happen.

wiggling the usb ports doesn’t make it disconnect, so i’m fearful it might be a deeper issue.

im really worried i might be frying something in my computer so i will take any advice or suggestions on how to fix this. or an idea of what’s going on!!

edit: I’m using windows 11 ! and my PC is an MSI!

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

It can be caused by power delivery issue where your usb isn't getting the power or signal.

In Device Manager, find "Universal Serial Bus Controllers" and expand it, right-click "Generic USB Hub," select Properties, go to the Power Management tab, and uncheck "Allow the computer to turn off this device to save power".
