When you change the motherboard you have to re-install Windows even though the hard drive already has Windows on it.
The existing Windows installation won't run properly (if at all) on a different motherboard.
Before doing that of course you need to test the hard drive with the drive maker's diagnostic software which loads from a bootable CD. The download links are here: http://www.tacktech.com/display.cfm?ttid=287

How is the drive attached? IDE or SATA?
check the port types in the bios. If its set to raid then you would only see the drive in the raid bios. I'm not sure if the ide port can be in raid mode. If its a sata drive then change the sata type to whatever mode it was in on the old board. The choices are IDE, AHCI, or Raid for this board. As long as its not raid mode then the bios should see it. If you pick IDE and it doesnt boot, go back in and try AHCI. I think the error message ends in 087b if its the wrong mode.
If even IDE mode doesnt see your drive in the bios then theres a good possibility your drive had fried too.

I installed a clean hard drive and reinstalled windows and it was alive for a week now the power switch on the case won't work so I jumped the green and black wire on the 24pin psu with it unplugged and the psu fires up so then I tried it connected to the mb jumped and all the fans start CPU,traffics card,case fans but there is no output to the screen what am I doing wrong have I just thrown £100 down the drain
You don't need to jump the pins on the power supply. The pins that the switch is connected to on the motherboard are momentary switches. You only need to
momentarily touch them together to get the PC to start. Reconnect the power supply properly and then touch the two pins with a small screwdriver or cut the wires from the switch and touch them together (the safer way) and the PC should start.
You should also test the HD on another computer to see if its good. You could also put an install cd into the cd drive, with or without the HD attached, and see if you get the boot screen.

Follow the wires to the motherboard and check that they are connected. If so, take the wires off and use the screwdriver method. Do you have a motherboard manual?
Does your motherboard have an led that shows that the power connection is good? It should be on when the power supply is connected properly. Did you attach the CPU power cable.

Does your motherboard have an led that glows when tho computer is working. For most motherboards this should be on even if the computer is off but connected to the wall. If its off you might have a power supply problem. What's the motherboard model? I'll look it up. Try your green and black jump again. Can you get a power supply from someone to test?
I looked a the motherboard manual:
http://download.gigabyte.us/FileList/Manual/mb_manual_ga-78lmt-usb3_v.4.1_e.pdf
It does not show a power led. Look at the jumper section on pg 18 for the two pins to jump. Try the green and black jump again. Did the fans spin? Borrow another power supply.

Go thru the manual step-by-step and make sure everything is connected correctly and jumpers are set correctly.
Clear/reset the bios as already stated.
Using just 1 stick of ram, 1 gpu, and NO drives connected see if it will boot up at least thru to 'No bootable drives found' kind of message.
If it does then you can power off and add in the other things. If it now fails to boot then take them out one at a time until you find the bad component. Windows crashing is not a failed to boot condition.

Done the manual step by step,reset the bios tried numorus hard ware configurations still nothing just voltages checked the psu that seems fine just the same problem as my last motherboard no out put at all now I could get a replacement mb as it's still under warrantee but I'm a bit concerned of it happening again as I can't keep going back the shop if it's another piece of hardware causing the fault
