*If you have another power supply use it to eliminate and determine the failing side.

*In case you use other power supply make sure it provides uninterrupted power and stable grounding.

    This LED turns <span style="background:green">Green</span>, the moment the memory initialization is successful.
 
    This LED is <span style="background:yellow">Yellow</span> while the memory initialization is in progress.
 
    If the memory initialization has failed, for example: There is no DIMM installed / the DIMM is not supported - the R LED will stay <span style="background:yellow">Yellow</span>.
 
    The R-LED should stay <span style="background:Green">Green</span> at normal operation, also after BIOS POST is over.
