Not sure what you're getting at to be honest. Could you try and be a bit clearer?

When the PSU is plugged into the mains, and the computer is switched off, it shouldn't spin.

ok

that helps, its obviously a faulty switch on pc then.cos when pc switched nothing happens,at all,even with all drives ect dissc.and tried 3 different psus.

Also, might as well check some other electrical equipment in same plus socket to double check the problem is not there.
Some PSUs have a 240/115v switch on them - cant imagine all 3 being set wrong but thats only other thing I can thing.
But previous post suggestion is most likely.

If nothing is happening when you switch on the PC, make sure the POWER_SW connector from the case is definately plugged into the right pins on the motherboard.
