On my B87 mini ex one of the rows of RGB LEDs on the bottom of it stopped working correctly. I have them set to be alternating between purple and cyan, half of one color and half the other. When I turn my PC on they work normally but after about 30 seconds all of the purple ones on the row turn to white and the cyan one on the far right side turns to orange. If I turn the LEDs off and back on with the mapped key then they will work correctly again then turn to the wrong color again just like before. Also when I turn the LEDs off, the one on the far left side of the same row will turn blue and stay on. How can I fix this?
