I'm facing a weird issue as well...to break it down

  • If I lock my PC and unlock it afterwards, the lighting effects are gone and the keyboards lighting is out. I need to restart the PC.
  • For some reason the NumLock, Caps Lock and Scroll Lock LEDs do not respond to the key strokes. Although the keyboard functions as intended. Meaning that I do not know if num,caps,scroll lock is pressed.
  • Finally I've noticed from time to time, some ghosting issues and the keystroke is repeated even if I press a key very quickly and only once.

Any ideas on the matter ?

Please note that the keyboard is the K95 RGB Gaming (not Platinum) if this post is irrelevant, please guide me to the proper thread.

Hi Tony,

We recommend performing a clean install of iCUE. Please follow the steps below:

Open your computer's Control Panel.
Open the Programs and Features options.
Select Corsair Utility Engine in the list, and then select Uninstall.
Press Window Key + R to open the Run command.
Type %appdata% and press Enter.
Delete any Corsair folders in the window that pops up.
Return to the Run window and type %localappdata%.
Delete any Corsair folders in the window that pops up.
Open File Explorer and navigate to C:\Program Files (x86)\ for iCUE 3, or C:\Program Files\ for iCUE 4.
Delete any Corsair folders in that folder.
Type Regedit in the Run window and then click OK.
Go to HKEY_CURRENT_USER\Software\ and delete the Corsair folder.
Go to HKEY_LOCAL_MACHINE\SOFTWARE\ and delete the Corsair folder.
Restart your computer.
Download a new installer file for iCUE from Corsair.com and reinstall.
