HP PS to wall LED on, PS to PC LED turns off. No power!

[38chev572]

HP power supply[PS} is plugged into the wall and the green led on the PS lights up just fine.  When you connect the PS to the power port on the base of the PC the LED goes dark on the PS, before even powering on and the PC will not display the power connected LED  or actually power up. I tried another PS with the same result.  Unplug PS over night and LED will turn back on but PS to PC same result.  The one time it powered up I believe i saw a bios message about overheating.  but can't get boot at all now. Do not know how to get around this?
