I built my new computer a few months ago but never managed to get it started.

When I boot nothing happens, nothing whatsoever. However the lights on the motherboard are lighting up when the PSU is powered.

Setup:
MB: Asus P8Z77-I Deluxe
RAM: Hyper-X 2x8GB 1600mhz BLACK
GPU: Asus GTX 470
PSU: Corsair CX600M
CPU: Intel Ivy Bridge 3770k

CPU Pins are not bent/damaged, I've checked.

GPU is working fine (used it on pervious build right before this build).
Tried taking out each ram, and also removing anything that is not absolutely necessary for the startup and still no sign of life.

The only way I have managed to start it up is by jumpstarting the 24-pin connector, however when I do that it is a plain black screen and nothing shows up.
