Using the keyboard freezes the system

[Mahany]

Hi Guys,

 

I have a problem with my laptop (Dell n5110 with GT525M GPU), When i use my keyboard while gaming a buzzing sound comes from my speakers and the laptop freezes until i release whatever key i'm pressing, sometimes the problem persists even after closing the game and the only solution is to restart the laptop .

I have tried to reinstall my OS and install the Nvidia driver provided by the laptop manufacturer as i read in a lot of topics that usually this problem may be caused by using different drivers than the manufacturer's supported ones, but still the same problem exists.

I borrowed one of my friend's USB keyboard and this problem disappeared but i'm not sure if it's an internal keyboard software or hardware problem. I don't want to buy a new keyboard for my laptop before making sure that it's a hardware problem because the keyboard is ridiculously expensive in my country.

 

A little help would be really appreciated here

#Update:

I have replaced the keyboard, but unfortunately the problem still exists.
