K70 rgb mk.2


Recommended Posts


I bought a K70 RGB MK.2 keyboard and I couldn't even use it yet, because it locks and no key responds.


I already pressed the ESC for 15 seconds and connected the keyboard; I already did the soft-reset; I already updated all the drivers; I have already formatted my operating system, but nothing worked.


It works for a few minutes and freezes.


Does anyone have any suggestions on how to fix this problem?


It seems that plugging it into a USB 3.0 PCI-E card or USB hub fixes the problem? Does it really work?
