Putting together new computer, failed to boot up

Hey guys,

Essentially my computer isn't booting up properly. I've got no response on my monitor, a LED on my MOBO and no beeps.

So this is my first attempt at building my own computer. I have pulled them apart before, so I had a rough idea of how it went together. Anyway after putting in all by bits and pieces, I went to boot it up, and noticed a red LED on my MOBO. Upon consulting my MOBO manual, it turns out it was the CPU LED indicating that there was a problem with my CPU, but does not explain what triggers the LED.

My build is as follows:
Corsair HX-750
CoolerMaster Hyper 212+ CPU Cooler
WD Green 2TB
WD Black 1TB
Corsair Force Serices 120GB SSD
Corsair Vebgance 8GB(2x4GB) DDR3
ASUS Radeon HD6970 DirectCU II 2GB
Pioneer BDR-206 Blu-Ray Disc Writer
CoolerMaster HAF X

While this is my first build, I'm positive I've attached everything correctly, as there are no other fault lights on my MOBO for the RAM, GPU or HDD and all the fans are running fine and the disc drive opens as well.

I have taken the CPU cooler off and pulled the CPU out and then replaced them, and still have the LED and no boot up response.

Any advice would be much appreciated

Make sure you've connected up the 4/8 power connector as well as the 24pin power connector on the motherboard.

Yeah that's all done

CPU fan connected I assume? Some motherboards refuse to boot if it's not connected.

Yeah, all the fans are running

Has this MOBO been a serial offender with problems?
