The most important thing is to

.......Approach the problem logically, if there are no blown components or tracks on the board and you have proven the PSU is not delivering the correct voltages then replacing the PSU is an entirely logical next step.

An ATX PSU doesn't just deliver all the correct voltages all the time though, it has some permanent outputs but requires a logic signal back from the board to which it connects to tell it to power up fully. If the new PSU doesn't "Fire up the Quattro" then you should check to see if the board is providing the required signal telling it to turn on,

Right, so the atx needs to be plugged in to the machine to power up? We were getting power down the 240v cable and to the on/ off switch but no voltage out of the cables & the fan wasnt coming on. ++ if thats the case how do i make sure we've wired up the cable correctly!

An Atx supply won't turn on without you shorting the signal wire to ground.
