No should be just green ...with blue x lit on bank selector
Does it do the same if u boot x3 disabled (hold power button in ...red x lit).
If it does the same then there may be a short cct on the back of the pwr/reset board .
plug your power switch directly back to the Motherboard does it go away
it maybe that you have a short between two LEDS on the back of this board.
You have to peel back the sticky stuff to get to the pins ...examine the solder joints one may be bridged.
