(logitechh g413 keyboard)some keys on my keyboard register twice and some keys won't register

[marcellino.clavinova]

my "h" keys sometimes won't register and many more keys like this are doing the same. I need to press my h key hardly or I need to press it long enough atleast for 1 second. is it a hardware problem or a dust probably stuck on my mechanical keys? also my n key sometimes register twice and also alot of my keys are registered twice. I've tried to adjust the repeat rate and delay rate on my keyboard but it won't work. any help is appreciated
