Please help. When my pc is powered off if a press a button on my keyboard or mouse the lights will turn on and they just don't turn off . The only way i have found to turn them off is to turn on and off the pc or just switch the psu off like in the switch on the back. Incase it matters i have the razer black widow chroma and the naga epic chroma. If you need any more specs please just ask. Any help or information would be great thanks
