Question Keyboard not turning on

[Romukami]

Okay, so i was casually playing, and then my keyboard just turned off suddenly and windows cannot recognize it anymore. Then i used my older keyboard which worked for a while until it stopped working too. I really don't know what could cause this and i have tried the following:
Updating and reinstalling drivers
Plugging both keyboards in and out
Restarting windows 10 multiple times
Using different USB-ports (which is strange since every other peripheral works normally)

Also here is my system info: Asus prime x570-pro, G.skill trident z rgb 2x8gb Ddr4, Ryzen 5 2600, gtx 1060 6gb, Seasonic 650w psu

It's the first time in my life I ever heard something like this. Anyway to troubleshoot, if you have a different PC / Laptop / Phone that can accept a USB keyboard, check the keyboards.

If the keyboards are not working, you might have to get a new keyboard. But this time, attach it to a different USB port and use it.

The problem is that i dont have option to try them in different computer and the older keyboard worked fine before i plugged it in for few hours

If that keyboard is old, we don't know how much life it had to run, right?

Usually when keyboards die, some sections of the keyboard stop working.
But in your case, the entire keyboard has stopped working, right?

So, we have to mark that USB port as faulty. Use another port for the new keyboard for safety.

Make and model keyboards?

How old is that 650 W Seasonic PSU? History of heavy use for gaming, video editing, or mining?

What other USB devices, if any, are or have been connected?

What you can do:

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all connectors, cards, RAM, and jumpers are fully and firmly in place.

Look for any signs of damage: bare conductor showing, melting, kinked or pinched wires, browned or blackened components, swelling.

The purpose being to eliminate just some loose connection or seating. And ensure that there is not some additional problem starting to develop.

= = = =

However, my overall thought is that the PSU may no longer be able to provide proper power to the USB ports. The first keyboard stopped working when the power faltered. The second keyboard worked until the USB power failed for good.

As suggested, do try the keyboards on another known working computer: family, friend, even at work if permitted.
