Keyboard makes strange rattling sound

[IvailoT]

Hello. I've had the HP Pavillion 15-bc005nu for over an year and a half now and recently the keys from right side of the keyboard (from the enter key to the num pad) have started to make some strange rattling sound whenever being pressed. The sound is not exactly rattling but I can't find another way to explain it. The thing is that they don't always make this sound but it only happens from time to time and after a while it fixes itself. Another way of fixing it that I've found is by pressing down hard on the whole right side of the keyboard with my hand. I've disassembled the laptop only once to clean the vents and the fans but I have never disassembled it completely. I'm not sure if this has something to do with the keyboard but I thought it's worth mentioning. Another thing that I've noticed is that the keys start making this noise when I've been gaming for a while, so maybe it has something to do with the laptop getting hot? Otherwise the keys work, everything works just fine but the sound is what's bothering me. If anyone has any idea what might be causing the problem please tell me because it's getting really annoying.
