Hello

My system config is:

i5-2500k
8GB ddr3 gskill ripjaw
Asus P8Z68 V PRO mobo
Cooler master 650W PSU
Radeon HD 6870

I have been using this system for the last 1 yr and it was working perfectly fine.

Today I removed the stock cooler and installed a cooler master evo 212 X heatsink.

"After completing the connection, when I press the start button, All the chasis fans and the CPU fan give a shake and go still.
The system is not starting."

What could be the problem?
Please guide me and tell me what to do.[/strike]
