I bought a new pc...

Gigabyte b75m-d3h 

I5 3570

2x4gb vengeace

OCZ Agility 120gb

Hdd 2.5 300gb 7200rpm

Radeon sapphire hd7950 dual x OC

Corsair 600cx

Thermaltake v4 black edition.

So, I installed everything properly, with all the cautions needed...all the power cords correct...

When a hit the power button, the surprise...NOTHING, NADA happens. The power led blinks once and thats all.

What could it be????? HELP please!

Thanks everyone!

Check the motherboard standoffs, There might be one out of place shorting the motherboard, which would cause that issue.

Double check every cable and piece of hardware, you never know some cables might be inserted upside down, or not pushed in enough... And did you put it together yourself or was it pre-assembled?

Have you plugged in the CPU power connector in the top left corner of the mobo? Built a computer with a friend, and that was the problem, with similar symptoms. Such an easy mistake to make :P

Hey guys, I never tried to clean the ram because it's all new..but I'm gonna try it.

All the psu cables qre connected.

It seems that it has power because the front panel led blinks. But then?

Coud be a bad mobo?

Thanks again!

I would resort to the test 1 thing at a time protocol.....starting with the PSU. Unhook the PSU from everything and test manually with a multimeter or a good PSU tester. If it checks out ok, then move on to the motherboard.

 

Remove everything except the power and video and see if it will post - (I would just use the integrated graphics to test if you have any). 

 

My guess is you'll find your problem at some point just trying these two tests. If not...move on the ram, graphics card, etc.

 

Good luck!

make sure you're plugged into "clean" power i.e directly into a wall socket, not a power bar or extension cable.

check to make sure that the 4 or 8 pin aux cpu power is plugged in as well as the 24 pin

try booting without the graphics card installed

test with another psu

make sure there are no bent pins in the front panel connections

Yesterday night I performed the tests...and the problem was a pretty basic thing...loose cable. The ATX 12V was so hard to plug hahaha. Bad mistake and lots of preocupation with this!
 
And the worst is that I unplugged and plugged that cable lots of time...apparently always wrong!
 
Thanks for all the help,I'm sure I'm going to have a lot more tools to solve similar problems on the next time. I'm feeling like an idiot, but it was my first build hahaha.
 
Thanks again!
