Welcome to GTG.

Do you hear the power fan spinning at least? If you don't, make sure the power cable and socket is working properly. If you do hear it, then it might be the motherboard.

Anything showing in your computer monitor?

it is doing absolutely nothing

Even the power supply unit? Do you hear anything? I think the power supply at least should be working since it's new. Check the power socket and make sure it works. Plug in a device and see if it turns on (try anything, night light, toaster etc... and see if it works).

If the fan inside the psu doesn't even come on & if the wall socket & the power lead all check out ok, then check the front panel soft power switch - the on/off switch on the front your computer should be connected to the motherboard. Pop the side off the computer case & trace the 2 wires that lead from the power switch in front of case to the motherboard.
Let me know if it's connected or not & if so, which 2 pins it's connected to (they should be marked with small writing on the mobo).

list the hardware specs too-the first time i built a computer, i forgot the atx power (4 pin[::]) to the mb right below the processer (only necesary with pentium 4 and 64bit AMDs.
