I have recently been told to take my motherboard and PSU out of the case and turn the motherboard on but how do i do this if it not in the case. Do I have to use a screwdriver to short the connection on the motherboard where you connect the on button on the front panel to see if it will turn on the computer.

First, Why do you need to take the board and the power supply out? Just test it while it's still in the case.
A couple main reasons for a dead computer,
A power supply. If you have a spare one, replace the old one and see if that works. If you have a voltmeter you can read the voltage coming out of the power supply.
On/Off switch. I worked on a PC where the on/off switch was bad. I had other covers so it was easy for me to replace it. If you do not have a spare, follow the wires to the board. Make sure they are the right wires, (you can verify this by either looking at the board's documentation, or simply look it up on the web). Then short the pins out. I would suggest using some sort of jumper. The idea is "troubleshoot".
Lastly, if it is the mother board, you won't be able to bring it up no matter where or how you plug it up.

the easiest way to test your power supply is to disconnect all devices apart from the hard drive. Switch it on and if you hear the drive 'spin up' then it is okay - in this case you should reconnect the motherboard and test all other components one by one. A dead computer is usually the power supply or the motherboard itself. Other components do not prevent the system from powering up - just these two.
PS - power supplies are available for around £15 up to £150 depending what you need - try the link below.

if the computer is "dead" you would first want to test with any extra parts your have... Power Supply being the most common issue with "dead" computer. to do this leave the motherboard in the case ( removing the motherboard is not going to do anything if the motherboard is bad.... test all the other companents first.... remove all PCI cards , all IDE connections, see if you get power, if not replace the power supply.... see if you get power.... if not.. your motherboard is prbably bad, then replace it(then you can worry about taking it out)

I have no clue why you were told to take the mobo out to try and start it. Like you pointed out, you usually can't start a system board if out of the case.
All you need to do is disconnect everything (drives, cards, memory, etc) except the Power Supply and CPU/CPU fan and then try it. If you do not get power to it, then it is most likely the power supply itself.
But you should not have to remove the system board to test it.

bad idea.. shorting with a screwdriver that is...
instead take the time to extract one of the switches from your front panel (power or reset... they're the same) and attach it to your mobo power lead for the test
