Brand new computer wont boot

[Guest]

Hello
I have just assembled a brand new PC. I have checked all the connections again and again. But still the motherboard LED's for the VGA and CPU blink red as soon as i try to boot.
Then it shuts down again without any response on screen or any movement from any hardware/fans.
I cant seem to figure out whats wrong since i have rechecked that the powersupply wattage should be high enough.
The specs are:
Intel i5 760 8mb
ASUS P7P55D-E EVO motherboard
nVidia Geforce GTX470 (Club3d)
8Gb Kingston 1600mhz DDR3 ram
60Gb SSD
1TB HDD
600W Powersupply

Be sure you have connected the 4 or 8-pin power lead to the CPU power socket, and that your video card power leads are firmly seated into the card.
