faulty psu's or faulty mobos

Sounds like something is shorting to me. This would explain why it is working when you have the connector 1/3rd out of the socket, it is not pushing the board up against the case.

When I was a lot younger I overlooked the riser screws inside the case and the computer exhibited similar symptoms to what you describe. Once I realised my mistake the PC booted and ran fine for another 5 years or so until it was replaced. I was lucky, but you can permanently short out a board if you aren't so lucky. This may or may not be the reason it does not work outside the case either.

Either double-check you are testing it outside the case on something non-conductive (NOT THE ANTI-STATIC BAG IT CAME IN!) or find some riser screws and put them into the case first.

I highly doubt both motherboards and both PSUs are faulty.

EDIT: Also check the heat sink is on the CPU properly and double check the memory, maybe even trying it with one stick.

@linktoinsanity, i have got the mobo on risers, i have just took it out of the case and placed it on a non-conductive surface plugged in the psu and still nothing, i know the psu is working as i connected lights to it and they came on. So i think it is the mobo.
 
Yeah, but with the 24pin connector it has a 4pin that clips on, i plugged that in at the end of the connector on the mobo where it should go and then use the paper clip and the cpu fan started, but when i plug it all back in it doesn't work. (i think that made sense?)
 
On that photo that shows the 4 pin connector plugged into the mainboard I can see Damage to the 20 pin area ......

Something has snapped somewhere or other, I should not be able to see through the side of the connector on the mainboard.

The only way you can have 4 components that all appear to have failed is having a common denominator as was stated earlier.

We need to get to a point that we know at least one component is good to give any further help :(

Yeah that's been there since i bought the pc a year ago this is the mobo that came with it. Its been working for a year, so could that be the problem then?
 
I'm going with a stray brass standoff shorting something on both motherboard and you've missed it.

I always double check the positions of standoffs before starting to mount the motherboard in the case. If the case doesn't have enough holes for the amount of the standoffs the motherboard needs, I use plastic standoffs in place of the brass standoffs. Nothing worse than trying to diagnose a fault then realising you have a flexing motherboard.
 
@darael, yeah i think i have missed it but i have checked all the standoffs and their position and they all seemed fine, if they can short the motherboard why are we advised to use them? And can you buy plastic ones because they wouldn't short the mobo should they?

Click to expand...

If there is a standoff in the a place where you don't screw the motherboard into, it can short it as it would be touching the board.

Seems off for both boards to be dead. You done every combo right?

Outside of case:

PSU 1 + Board 1 + CPU, 1 stick of RAM = Dead
PSU 2 + Board 1 + CPU, 1 stick of RAM = Dead
PSU 1 + Board 2 + CPU, 1 stick of RAM = Dead
PSU 2 + Board 2 + CPU, 1 stick of RAM = Dead

Hopefully the new stuff works OK.
