Mfarseer wrote Just wondered, even if I do reassemble everything and short the pins and it still doesn't work, would that necessarily mean it's the PSU at fault? Or can it still be a motherboard problem?


You are still in the trouble shooting phase. Doing this should figure out what is at fault. If you can confirm that power is coming in, and going where it needs to go, then you know whats not working

Okay.
So ill go through with what tests I've done.

I didn't completely uninstall the motherboard from the case as suggested, I simply worked with it still in the case.

I used a PSU tester and the PSU displayed correct voltages.

So, then I tried to short the power pins on the Mobo with nothing but the fan, 24pin and CPU connected and nothing happened. Still heard the same click sound but nothing else.

My only guess is that it's a MoBo/CPU problem?
In which case I should just RMA both in order to save time and cost? (as I don't want to buy a new CPU, install it and then have the faulty MoBo kill it)

This shortcut will loose you time in the future which you're paying for now.

That said, you're right to be cautious about a new CPU so yeah, a new motherboard would be best but you're taking it out of the case anyway so why not test it whilst it not in there just to, as you've said, save time and cost?

I mean you can RMA them both but I'd do the motherboard first then the CPU later. At least you'll know what was causing the issue. Just be careful when putting it back into the case if you're going to skip testing. You don't want to put it all back in only for the motherboard to short and you're back at square 1 again.

So you reckon I should still take my current motherboard out of the case and test it with the CPU and 24pin first. Then if it doesn't work, replace just the motherboard and try testing the new one with my current cpu? If its a bad cpu would that not ruin the new board?

Also, can I simply turn on the motherboard with just the 24pin connector and no CPU? I know it wouldn't run but would any power led lights show up even briefly? Then if it does then wouldn't that prove that the CPU was the problem? (as with it connected, the lights don't show)

Sorry if I sound daft lol

Well, I tested the motherboard outside the case and still nothing. Except now when I short the pins I don't even get the click sound from the PSU like before. So, rma both board and CPU or just the board?
Such a pain this is
