Windows 10: Some keyboard keys stop working randomly on windows

I have Dell inspiron 7577 laptop which was working without issues.. a few months ago some keyboard keys numpad 1,4,5,7 have stopped working completely..And yesterday keys F12 and numpad / also stopped.. I thought there was some problem with the hardware.. but today I booted a recovery cd based on WINPE and the keys came back to life..Back to windows and they stopped working again.. now they only work on that boot cd..What's even stranger is that the F12 key is used to launch the BIOS boot menu.. it also stopped working yesterday at boot time as it did in windows.. but still works greatly in

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
