OK, SJ only has the picture of the top side of the board, so you will have to take really good pictures of the bottom side of the board for us.

budm the light here isnt very good today ive took the best i can at the minute i hope these will help for now.
budm just a update i have just found a parts board ive tested the 5vst too earth and it also reads .000 so maybe this isnt the fault causing the clicking relay.
on one of the pictures ive uploaded on the edge of the board theres two small capacitors that go across the 5v st and gnd pins these do read short on both boards sixth picture.
They are basically connected in parallel because they are connected to the 5VST pins. I would remove one at a time to see if the shorts will go away otherwise will have to trace that 5VST connections to see where else it goes to. These MLCC they tend to fail as shorts circuit.

could bad capacitors cause the clicking? i could remove all and test esr etc as soon as you plug it into the mains it starts clicking the relay if you then remove all leads and just have the power lead in you can hear the psu ticking so im sure its a psu fault.

We need to find out first as to why you are getting such low resistance on that 5VSTY output, we will have to trace out and see if that 5VST also used to feed other circuit on the board.
