PC turns off seconds after turning on power

Pavilion 500-223W
Microsoft Windows 10 (64-bit)

I have side panel off and see the fans working, after a few seconds PC turns off. Power button won't work, will only come back on after plugging it into outlet and then only for few seconds.

Some computers, as soon as they detect AC power, such as when you plug the power-cord into the wall outlet, will do a quick "power-on-self-test", which includes spinning the fans, and then turn themselves off.  Is that what you have observed?

 

It could be:

 

* the power-switch is broken;

 

* the two wires from the power-switch no longer are connected to the correct "pins" on the motherboard (loose?);

 

* power-supply is broken.  While watching the fans, press the POWER button.  Do you see a brief "wiggle" from the fan-blades?  If you do, then the power button is working. Got a spare power-supply to temporarily connect to ONLY the motherboard (not to the disk-drives), to substitute for your power-supply.

 

* motherboard is broken.  No easy way to "test" this.

 

Disconnect the AC power.

Remove all of the sticks of RAM.

Reconnect the AC power.

Does the computer "beep" to complain about the lack of RAM?  It's a good sign if it does beep.
