Continuous Beeping on Gigabyte Z77-D3H Motherboard when I power on

[DrTardis1]

I reccently purchased a new case, CPU Cooler, Fan Controller and Case fan for my PC because the internal temperatures where a little high for my liking, however the computer always functioned without issue.
After moving my Mobo and all other internals into the new case and setting it up properly, ive found that it will no longer start. When i try to power it on, it will make short beeps constantly until it powers itself off and will then power back on and continue. Ive made sure all cables are plugged into the right places and plugged in properly. Ive also tried taking one of my two RAM sticks out and testing it in every slot and did the same with the other RAM stick. So far, nothing works. Does anyone know what the problem may be and how I can fix it? Thank you in advance for all your help

Specs:
Mobo - Gigabyte Z77-D3H
RAM - 2x 8GB Geil Evo Volce
Case - Aerocool Xpredator
CPU - Intel i7 3770K
CPU Cooler - Coolermaster Hyper 212X

Your motherboard should have a debug LED on it. Check the last number displayed on that LED before the computer shuts down. The motherboard manual lists the codes and what they tell us.

Recommend running this test with the MB out of the case and with just the CPU fan, memory and graphics card installed. Also make sure that the CPU fan/cooler is attached to the 4-pin CPU fan header. The MB will probably not post unless it sees a fan connected.

That beeping sound your hearing is known as a 'beep code' - each code refers to a specific problem that is stopping the PC from booting properly.

Refer to your manual to find out what it's trying to refer to
