My keyboard isn't functioning properly.
My keyboard isn't functioning properly.
I'm experiencing issues with my keyboard recently. A few days ago, when I turned on the computer, it began to malfunction. Writing caused sentences to be incomplete because many keys didn't work properly or repeated characters excessively. I assumed it was the keyboard problem and decided to replace it after a long time. The new one arrived, but the same problems persist, this time more severe. I've tested all USB connections—both 3.0 and 2.0—and both the ones included in the box and those on the board, but nothing helped. I also tried booting Windows in safe mode to check for software issues, but it didn't resolve the matter. Since I wasn't certain about safe mode, I attempted to start Hirens Boot on a USB drive, which also caused the keyboard problems. It seems the issue might be hardware-related. I'm wondering why only the keyboard is affected and not other peripherals like the USB hub, USB headphones with DAC, or the mouse. What steps should I take next?
Could you clarify whether you're referring to a wireless keyboard using a dongle or a wired USB keyboard?
It's unusual that all other functions are normal except the keyboard, which seems to not work properly even when connected to the same USB port as the mouse.
You have the ability to generate a Linux "live" DVD or thumb drive that operates solely in RAM without installing on the system. I’ll recommend trying it, and observe if the problem continues across different operating environments. If it persists, it likely points to hardware issues; if not, it probably relates to Windows.
Numerous bootable DVDs and thumb drive images exist. My usual choice is KDE-based Ubuntu. You might find more options here:

You could also explore various applications in your Windows installation to determine if the behavior changes.
An unusual test involves checking installed games with customizable keyboard shortcuts. Adjusting a binding setting and assigning a key to a "badly behaving" character can reveal whether the issue lies with the hardware or the software comparison logic.
For instance, some games use scan codes to detect shift key positions rather than relying on the actual scan code values. If these bindings succeed despite errors, it suggests the hardware is functional, and the problem may reside in how the software interprets the key inputs.
I attempted to start from a Hirens Boot USB to check for Windows issues, but it remained unchanged... 🥺
Next, I'll test using a game.
Would you like advice on using "toram" with Kubuntu on a USB drive?
Trying Linux was your approach to check if the OS was the problem, at least I would just remove the side panel and unplug it, then reconnect the USB wires to the motherboard while using a flashlight to inspect all USB connections for any damage or dust.
