Windows 10: My keyboards w key stops working for a few seconds

this problem started a 2 weeks ago and every time I press my w key there's a good chance it won't respond and I just have to hold down the key longer for it to work and sometimes when I still hold down the key it still just stops responding

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

What should i do ?

 

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...
