Keyboard issues in CS:GO

[Satoscio]

So today arrived in my mail the new Cooler Master Masterkeys Lite L, and when i started playing cs:go, I noticed various issues:

-When I press tab to see the scoreboard, it shows for like 1 second and keeps flashing
-At round start when i press W to move forward, it moves slowly like I was pressing shift and after 3 seconds it returns to normal.

What could it be?

Nevermind, I solved this by changing usb port on my computer
