new system build not turning on

[azurite2]

okay so I just built a new PC and I'm plugging it in and turning it on and it wont turn everything on. the motherboard comes on only because I can see the lights but the graphics card hard drives all that is not coming on. any help would be much appreciated as I don't want to send all the parts back

Do they have power?

[SkywardKkalox]

Were you using an Anti-static strap?

Also, try using 1 ram stick at a time maybe.

And the PC will only start when the led indicator on the motherboards turns off, if it doesn't consult your manual with the error code that the led is giving.

It would be useful if you gave us the specs

Is your display output on your gpu and not your mobo

[Cactu]

Also more detail please and specs

[bhagatneel15]

Make sure you start with your display attached to your mobo, you probably have some driver issues with your GPU

Does the motherboard stay on or does it switch itself off after a few seconds?

 http://pcpartpicker.com/p/tRX9pgThis is the part picker site. The fancy red LED's on the mobo come on but nothing else no HDD or anything else. I started with the display plugged in as well.

At least the leds on it stay on.

At least the leds on it stay on.

does the CPU fan keep spinning while the leds are on?

I think I figured it out, I'm just an idiot I forgot to hook up one of the cables.

let us know if it is fixed.   (cpu atx header?)

Ya although I don't know what to search for to find that cable.

If you've never forgotten to plug one of those in then it's because you haven't built enough computers

 

It should be part of the PSU cable kit. 

 

EDIT: is your PSU modular?  if not it will be there somewhere, probably hidden behind a clump of cables.

Yes it is modular but the only one I had, I needed for my GPU, unless I did something wrong

yes they are different, there should be a separate one label PCIe or similar for the gpu, the ATX one will only have 4 pins.

Ok you are the best person in the world it is working now! The bios however is very yellow is that a problem?

 

Edit: also if you couldn't tell this is my first build how do i get the OS on the computer?

What video cable are you using, if it's vga it might just be loose or a dodgy cable, for anything else wait until you get the OS on and the all the drivers updated and see if that makes a difference.

 

We all start somewhere,  I've seen experienced builders (myself included) that overlook or misplace stuff like this, it's par for the course.
