64GB? Are you sure? That would be 4 DIMMs, each 16GB in size. Memory totals greater than 32GB and DIMMs larger than 8GB in size are *not* supported by this board. If you really have this size DIMMs, this will explain why you are seeing an issue...
Presuming that that was a typo, please explain how you got to this point. Is this a new build? If not, what happened (be verbose in your explanation; explain what happened, what did you attempt to do about it, etc.)
32 gb sorry by the mistake .
i solved the problem ,
Connect the power supply to the motherboard and made a bridge by attaching the green wire to the black wire. Then connect the source to the electric current and the computer turned on, generated a bios error but came back to life. Then remove the bridge I made and the computer now works correctly. I think the bios suffered a short or something like that
Hhmmm, could this be one of those situations where the power supply requires a certain load before it will power on and the motherboard (with processor, etc.) is (still) not meeting this loading requirement?
