Computer not starting.

Hi guys, just got my PSU back (old one broke so sent it back) and got a new one today - http://www.overclockers.co.uk/showproduct.php?prodid=CA-059-OC&groupid=701&catid=123&subcat=1098.

I've set everything up, put all the cables in ect. however when I go to turn my PC on, everything seems to go on for about 1second then switches off. My blue led fan goes on (I see a flash of blue) the fan on my CPU goes on for a second. Do you guys have any ideas? Please help!

Did you manage to connect the 4pin <a class="ktg6us78hf8vdu7" href="#">cable</a>?

Yes, I had to split the 8pin one (didn't occur to me at all in the hour I spent scratching my head). However still no luck in the computer working

Yes, the old PSU I had was http://www.overclockers.co.uk/showproduct.php?prodid=CA-167-CM&groupid=701&catid=123&subcat=1103

and yes, my mate put his PSU in and it worked perfectly.

One other thing. After the computer goes on for a second, the PSU makes a low quiet sound after everything else goes off. It's like a hum

I've double checked everything and still no joy! Argh this is annoying!

Changed the socket I was using, took everything out and back in again, still not working. That kind of low squeel is still coming out of the PSU when I turn it off. Does anyone have any ideas?

Yeah my mate is bringing his rig down tomorrow so I can check it all then. It's a brand new PSU so the chances of it being the PSU is slim I would have thought. I took all the wires apart, even did the CPU again, put it all back together again and still the same problem, everything starts for 1second then turns off. I've taken out the battery for 1minute, put it back in. I've taken out the RAM with the battery and put 1 stick in each slot (with the battery in) and nothing. I'm running out of options, no idea what to do.
