Windows 10: Some keyboard keys stop working after few minutes after start on ASUS X750JB, Windows10

Hello,

This thing is driving me crazy. Please help :.

Some of my keyboard keys stop working after a few minutes after I start Windows, mainly in the Numpad Area :
Keys : 7, 9, Home, PgUp, Num lk

PC Specs : ASUS X750JB

BIOS is at last available version : American Megatrends Inc X750JB.208, 8/14/2013
Windows 10 Pro, 20H2, OS Build 19042.746
PC : IntelR CoreTM i7-4700HQ CPU @ 2.40GHz 2.40 GHz

What I tried to fix this :
1. In Device Manager - I uninstalled the "HID Keyboard Device" + Standard PS/2 Keyboard and restarted PC.
Current versions on the 2 drivers:
HID Keyboard Device - 10.0.19041.1 6/21/2006
Standard PS/2 Keyboard - 10.0.19041.1 6/21/2006

2. Disabled fast boot in Control Panel

3. Keyboard keys are clean, because they all stop working at the same time after few minutes

4. Troubleshoot Settings / Keyboard area => gives me nothing

In ASUS website I can't find newer versions of these drivers, just ATK package
What are the drivers that I should update ? and WHERE are they

What other solutions can I try ?


Thank you for your time and help.

Kind regards,
Alex

random keyboard keys stop working?

i went out today and everything was fine, i come home and three random keys stopped working, maybe more i havent noticed yet. the three key on the left side of the keyboard not working, the left shift stopped working, and the enter key stopped working, but the one on the numpad works fine. no one was home to use it, nothing spilled on it, i tried it on another computer and same deal. im gonna go buy a new one tomorrow but it makes me sad cause i loved this keyboard lol, microsoft ergonomic 4000. ill probably buy the same exact one if its in stock tomorrow, this one lasted or 4 years about. im just confused why three random keys spread out stopped working at the same time...seems very weird

 

Keyboard stops working

Three or four times a day the keyboard stops working for about 5 minutes. I can't enter text or use any of the keys. I can't open Task Manager with ctrl-alt-delete to investigate. The mouse still works. I can use it to close or open programs, shutdown etc.
Does anyone have a suggestion on what may cause this or can recommend how I can track down the culprit?

 

Keyboard Volume Keys not working while in-game

I happen to have used the Tt Challenger Pro keyboard in the past, and the volume keys worked flawlessly in every game, so it's indeed a weird problem. I would suggest the same thing sneekypeet suggested, using the keyboard software and assign this function to a hotkey, but you said that didn't work either, so yeah...
