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

Meanwhile, I would suggest you to refer the troubleshooting steps mentioned below:



Change Power Management settings:



If you are using a wireless mouse and keyboard, try changing the power management settings. Refer the steps mentioned below:

Disable USB selective suspend setting:



I would also suggest you to check the USB suspend setting and see if that makes a difference. Refer the steps mentioned below:

   OK.
