I can't get my newly built computer running

Hello,
I just recently built a computer and I can't get it working correctly. I can turn it on fine, all the fans engage, it starts whirring, etc., but after 2-3 seconds it beeps at me and nothing ever comes up on the monitor. I thought I was ready to install my OS, but apparently something is awry.

I have the following parts:

Intel Core i3-2120 Sandy Bridge 3.3GHz LGA 1155 65W Dual-Core Desktop Processor

So far I have taken the following steps:
1) Plugged the monitor into the mobo as opposed to the graphics card
2) Pull out and reinserted the RAM (it is in the A2/B2 slots where it needs to be and is clicked into place)
3) Checked the mobo's onboard lights. Both are on which should indicate that it's working normally
4) Checked the graphics card to make sure it was powered and secured.

I'm unsure where to go next. The only thing that didn't come with a manual was the hard drive, but it seemed as simple as plugging in a power connection from the PSU and then a SATA line into the motherboard.

Does anyone have any advice on where to go from here?

  1. I would start by unplugging the hard drive, DVD and then removing the video card. Plug the video into the motherboard.

    Next, I would be sure your motherboard has both power cables connected (I built a server that only needed one, the big one connected. But then on my gaming build I missed the smaller one). Looks like yours has one behind the ps/2 port.

    Then see if the computer will POST with only the MB, RAM, CPU and PS connected.
  2. Keep in mind you'll get more response if you name the products with the links. A lot of people don't want to open every single link to every single part in your build.
  3. Agreed, it was annoying to click every single link.
  4. also check that the factory put the cmos clear jumper in the right pins. (not in cmos clear mode). also check that your hard drive/power/reset led are on the right header. the mb could be stuck in reset mode. if there no power from bare boing it check that you dont have a stand off or the i/o shield shorting out the mb. sometime people forget a stand off and the mb is tuching the case.
  5. I unplugged the graphics card and lo and behold it booted up. I was hoping it was maybe just a bad connection so I plugged the card back in, and it's back to nothing.

    Do I perhaps not have enough power?

    I checked the cmos jumper already and it's in the right place as far as I can tell. The power/reset wires look like they're on the right pins as well.

    The problem currently seems to be in having the GPU connected.
  7. did you plug in both 6 pin pci plugs?? the power supply is rated for over 50 amps. that fine for a small card like yours. so you have another video card in the house or that someone can let you use to see if it the mb or video card. dont want to you start paying for shipping good parts back. i would look at the card and inside the mb for any bent pins.

    Both plugs are connected, yes.

    I might be able to grab my roommates card, he has the one a step below mine so it should be relatively similar.

    The mobo has onboard lights that are supposed to indicate how it's working, both of them are on which is supposed to signal that everything's good. I'm not sure if that's relevant or not.
  9. I figured it out. Such a simple mistake that I feel like an idiot.

    My monitor was on analog instead of digital the first time I plugged it in to the GPU...

    Thanks for the help guys
  10. I know you solved the problem but for other people that might see that and have the same computer, it might be the motherboard's fault because of BIOS update or something like that, which makes it impossible to start with that CPU.
