The meaning of the debug code of 15 is: Pre-memory North Bridge initialization is started

"North Bridge" should be referring to the Z77 chipset on your board. That might be the problem, or something related to it.

Note that the description states "pre-memory", which means the memory has not been tested yet. Your memory is not causing this problem.

It would be much easier to help you if you listed all the parts you are using in your PC.

Did you connect the eight pin CPU power connector from your PSU to the mother board?

What CPU cooler are you using?
