ok here is the problem, for some reason, the left "alt" key is same key as "h" key and right "alt" key is the same key as "n", and the "num lk" key is same as "u" so when you press h + F4, it closes window just the same as when you press "alt + F4", so when i type fast, sometimes i open random windows or perform random actions. it is really annoying and especially the  "num lk" key which activates the numbers so everytime i press "u" i have to deactivate the "num lk".

 

anyone have a similar problem or a solution towards it?

 

thanks,
