Help Wanted Problem With My Keyboard

[Electrikoh]

So this recently happened while i was having multiple problems with my keyboard. 

First my arrow keys switched with my WASD keys which i fixed by using Fn + w.

Then my whole keyboard started not working so i opened it up from the back of it. There were no loose wires and i didn't do much movement

to the aluminum plate inside as to not damage anything. The circuit is looking fine though.

Then i realised that i had pressed Fn + F11 while spamming everything which stopped all keyboard inputs.

And everything was fixed but i realised that while playing Left for Dead 2 while holding tab the tab menu flickered.

It happened after 1s of holding and it flickered very fast, like youre holding down a letter and it kept going. It stopped after i held down another key during holding tab.

I think its a keybind that i pressed during spamming but i couldnt find anything on the web as to how to fix it. I need some help because its hard to play while all my keys are repeating
