A -- If only the yellow ligth is lit, this means the computer is off and receiving power. A B C - If A B and C are yellow, this means the BIOS is not running or not finishing (completing its POST). B -- If B is yellow, this means you are having some type of issue with the power supply. C -- If C is yellow, this means you have some type of problem with the motherboard. A B D Yellow and C Green -This means you could have a problem with your CPU. A B Yellow and C D Green -- This means you have memory installed, but there is a problem with it.
