Sounds like the power supply caps take the back off look for mushroomed caps or black marks on the top. take a picture and post it someone will join in and help.

Indeed,

Open the back and take a picture of the whole back so we can see the layout, then a good quality pic of each of the boards and any writing by any of the connectors.

Pics from straight above and no flash

It could be a mainboard also. Ones I had a PS_ON signal keep switching on and off.
I have removed that pin from the connector and I have measured it separately.
