PSU oczgxs850 (working tested on my old MB)
CPU i5 3750k
MB ASUS Z77 Sabartooth
RAM Corsair 2x4 8GB KIT PC3-12800 DDR3-1600 CL9 Vengeance
GPU GTX 470
Case Coolmaster HAF+

The problem is when i power on the green led lights on the MB. Then i turn on with the power button on the case the GPU fans turn, the lights on the case light up but nothing else. I assembled the MB,ram,GPU on a table but no joy.
also i have tried one stick of RAM in each solt, Flashing the BIOS, cleared the cmos,
The PSU i know is working it was tested on my old MB.

A little help would be great,

Is there any signal going to the monitor? Could try switching from gpu to onboard, or other way around.

After you power it on, does it stay running or turn off? Is there a hard drive attached? If it has windows installed turn up your speakers and see if you get the windows loading tune after a while. If this works then it means the system is fine its just a monitor issue.

it does not even run the fans on the GPU spin but they just get enough power to start turning. when the PSU is connected to my old MB it starts no problem.
but with the new MB there is nothing just a green light to say its on. no other led's light up on the MB
