Legacy Boot Event issue

PLEASE HELP my brother is building his gaming PC for the first time. His specs were 8GB of ripjaws ram, AMD athelon processor, radion 7770 core edition and a Bio Star Hi-Fi A85w. Also 1TB WD cavair black. After we put the PC together all the fans would spin up but no signal would come up on the moniter. The motherboard then said A3( legacy boot event). 3 hours later we have tried everything but no progress. We tried starting it without the graphics card, the we redid all the sata cables, then we checked and triple checked all the wires, we the redid all the front panel connectors and make sure they were perfect, then we unplugged everything and replugged it back in, and then we restarted the CMOS and still at A3. Please help straight away for we need this computer finished as quick as possible

    The motherboard only supports 3 Athlon processors.

    If the processor you are trying is not on the above list it will not work. You will need to change the motherboard or processor.
  3. If you're not getting anything sent to the monitor then you MB or RAM is likely the culprit and will need to be RMA'd.

    Try the ram sticks 1 at a time to independently test, and I'd try any other ram you have lying around in the box also. If still nothing its highly likely the MB is trash. In addition while trouble shooting remove as many varibles as possible, so use the onboard graphics.
  4. The Athlon series does not have integrated graphics. So using the motherboard VGA/DVI connectors will not work.

    Ok, so leave the vid card in, or try another one and remove everything you can including the HD. If the OP can get past the bios try an Unbuntu boot thumb/disk.
