look at the silver top cans(capacitors) on the motherboard to see if any are domed or leaking brown stuff.

i have triple checked all of them and there is no doming or leaking, there is no scorch mark on the mobo, no scratches or anything, its a complete mystery to me.

disconnect all drives & cards except for videocard unless the board has onboard video. try clearing the cmos as have found that to work sometimes to kickstart a stubborn system. remove all ram to see if powers up or not.

do you have another power supply to try as it sounds like the connection at the motherboard is problematic.hopefully its just the plug.

Clean the contacts and pins on the 24 pin connector... do a scrub/scratch job on the pins.
sounds like dirt buildup on the 24 pins at the bottom if it works partially pushed down.

it is starting to sound like the board has gone south.if you push the plug partway and the fans spin up that does not mean everything is necessarily getting power.if you have a defective component that hasnt got a good ground it may be feeding back thru another circuit.essentially trying to use a live circuit for a ground.sorry but its easier for me to understand than to explain.lol

Me too, I stopped explaining it years ago when I sold my Oscilloscope and stopped soldering parts on MOBOS. Now it's a plug and play, just replace it.lol

kenny2014, try the board & psu outside of the case with just 1 stick of ram to see what happens.
2oldGeek, i still solder motherboards & cards to fix them.

When you're as old as I, everything has dried up or leaks......

& why does that stop you from soldering as maybe a bit of soldering will stop those leaks.
