After install the new power supply computer don't start. It has only one LED light up with initial J53 on the corner of the motherboard. Try to use a different power supply from an old computer that has the power supply connection for regular hard disk, not as the new computer with SATA connection, but this power supply seam to start the computer??? why new one doesn't? Can be broken from factory?? any suggestions? fix other computers before but this case never happen.
Thank you
