Windows 10: how do I fix my devices disconnecting and reconnecting every 2 seconds, and how do I stop...

here is a video showing how all my devices disconnect and reconnect every 2 seconds, there is also an audible windows sound effect every time they disconnect, but you cant hear it in the video. I haven't tried anything yet because I'm not sure what to do. because of this issue, I can connect controllers or headsets and it causes games to freeze and crash a lot. plus there is this annoying noise replaying every second. I have already tried restarting my computer but it didn't change anything.https://youtu.be/S4BgQYiePJ4?si=IAe0HHY7REfCHGP7

USB devices disconnecting/reconnecting

Hello everyone!

Lately I've been experiencing a problem with my network adapter (and other USB devices along with it) disconnecting and reconnecting. And before anyone asks yes, I've searched whole internet upside down for answers and tried every possible fix that I could find but nothing worked (and yes, that includes the whole power saving and hardware troubleshooting thing).

The problem started out as my USB network adapter from Realtek infrequently and randomly disconnecting and then reconnecting few seconds later. Some time later it would disconnect all USB devices along with it. I'm not really an expert in network adapter field but I thought it could be because of the adapter (considering it was already quite old) so I went and bought new adapter.

However, even with new adapter the problem remains the same but now it's not randomly disconnecting but rather when downloading big files (for example video games) or even when listening to music on Deezer and I press skip one too many times. For example, yesterday I was updating games on steam and it was downloading and then it just stopped, followed by disconnecting sound and network adapter, mouse and keyboard not working but reconnecting few seconds later (I should also mention when the hiccup happens Chrome seems to stop responding until my computer is connected to the internet again). I tested current adapter on another computer (that is in the same room as router) and it worked without any problems so at least I know it's not because of adapter. After I got new adapter I also did clean install but the problem is very much the same.

Does anyone know a way to fix this problem? It's getting really annoying that I can't download anything without my internet along with all other devices disconnecting (especially 'cause my schoolwork is really computer and internet based).

EDIT: I've also experienced more than once that after my network adapter disconnects and disconnects mouse and keyboard with it, it takes longer for them to reconnect and when they reconnect they don't stay reconnect much longer before disconnecting again, rendering every USB connected device useless.
EDIT 2: I also seem to have started experiencing this problem when I switched motherboard few months ago due to old one being fried by PSU (I replaced both PSU and motherboard) so could it be motherboard's fault?
FINAL EDIT: Finally went and looked over whole motherboard and it looks like I've got faulty motherboard. Thanks everyone who tried to help with problem!

 

USB devices disconnecting/reconnecting

You seem to have a number of issues going on with your PC that you might take a look at that motherboard.

Anyway it would help if NerdSquardMember expanded on their suggestion. That said, it may not be an IRQ conflict. However, you can easily check your network adapter by simply going to Device Manager and right clicking the adapter, then clicking Properties, then click Resources...




If there is a conflict, it will be shown

You might also go to the Power Management tab there and un-tick "Allow the computer to turn off this device to save power"





Let us know if this helps.

I turned off Power Management but no luck. As for the Resources tab in Device Manager, it's not showing up for my network adapter. I tried reinstalling it and updating it but it's not showing up.
