Pc don't turn on.

Hello Everyone.

I have a trouble with a new Mobo or Cpu or Case.I bought them just on Xmas and installed them in a new case.

When i click the power button it do nothing at all.Psu and Gpu is fine, I tested on old Mobo.Ram isn't a problem aswell.

The funny thing is , when i did an ´Breadboarding´(Only with cpu and cooler and mobo. lol) the Cpu cooler on Mobo starts, which I hope indicates that it's all right.

I didn't use a screwdriver to start, but i did connect cables from old case to F-panel.

So what's wrong with my pc?

Btw i have 3 Case coolers.

(Sorry for my grammar)

Specs old:
Mobo - Asus m4a87td evo
Gpu - Gtx 560 ti oc
Psu - Corsair gs800
Cpu - AMD Phenom II X4 965
Hdd: Toshiba mk1002tsk8
Cpu cooler: CM 212+
Case - Can't tell it's really old like 10 or more years.The diffrences in F panel cables are that old has speaker and new one hd audio and ac 97.

Specs new:
Mobo - Gigabyte ga z77x-ud3h
Gpu - Gtx 560 ti oc
Psu - Corsair gs800
Cpu cooler: CM 212+
Cpu - Intel i7-3770k
Hdd: Toshiba mk1002tsk8
Case: Zalman Z9 plus

try using the screw driver when its installed in the case to rule out the case power button/cables are bad. if not then it might be a short somewhere when its install in the case.
