After installing my new cooler I've put everything back in, but the computer just wouldn't boot. No fans, no lights, no anything. The only thing that lights up is the LED on my graphics card that tells me that the PSU is probably fine. I've done everything mentioned here : http://www.tomshardware.co.uk/forum/261145-31-perform-steps-posting-post-boot-video-problems. Is it possible that I have damaged the motherboard by applying too much pressure while mounting the heatsink?

My specs:
Intel Core i5 4690k
8 GB single channel HyperX Savage 1866
ASRock Fatal1ty Z97X Killer
ASUS GTX960

You've done everything listed in that link?

You're sure all power connectors (the will be at lease 2 points on a motherboard you have to attach - the CPU power & main motherboard power. Off the top of my head those are 4or8pins (CPU) & 20or24pins. One of the most common mistakes is failing to attach the CPU power connector.

Did you breadboard? Try to POST, outside of the case with only the CPU/HSF/Mobo/1xRAM+PSU connectors?

It's possible, but unlikely that (reasonable) pressure applied to the motherboard damaged anything.

I would suggest you breadboard first, no GPU, outside the case and see if it posts.

The LED on a GPU is not a measure that your PSU is ok. An LED requires minimal power, especially compared to a CPU or...

You didn't actually list the make/model/wattage of your PSU, so it's impossible to get an idea at this point.
