Hi everyone,



Today I started to notice a very strange problem.

There are some keys on my keyboard not responding anymore.

The keys are following :



Top row : ESC, all function keys (F1 --> F12) print screen, scroll lock, and the one on the left from 1/! (just under ESC)



Did anyone have this problem before, and were you able to solve it?

I have a color that lights up when I hit a button, and that isn't happening either, so I'm worried it's hardware ...



Also tested it on another PC, same result..



Thank you in advance.
