Can't get the POST screen to show up again.

Hi! So I've just now built a home computer just a few hours ago.

So after I built it, I attached the video cable to the GPU to get video on the screen, and to my luck it worked!
I got a flash or POST screen and I was satisfied I did. So I attached a keyboard and mouse USB to the front of the computer and after turning it on a second time the computer didn't go into POST. I restarted a few more times to see if that would help and unfortunately it did not.

I have no idea what happened to my computer, and why it only showed the POST screen once and refuses to do it again. I can see the monitor light up and everything, but it's refusing to show any signs of being able to enter the BIOS.

Did my GPU magically get fried? Is there something I'm missing? I just want my computer to work, It did once, I just don't know why it won't again.

More about post screen show again
  1. Use this guide for help:

    Please come back with the results.

    Good luck!
  2. As I said before, I have already entered POST once. It's just not doing it again whenever I try to re-boot it.

    I went through the checklist and I'm still not receiving any POST.
  3. since you had a first post without mouse and keyboard did you try without them to get a new post
  4. Try using the integrated video? could be a short on the front panel?
  5. Tried without a mouse and keyboard, didn't work again.

    And yes I'm using the integrated video card.
  6. remove the video card, reset the bios, and see if the cpu fan run when you turn it on.
  7. I don't think you're getting what my issue is.

    When everything was built together it ran fine for the first time. I achieved a splash screen and I could've gone into BIOS if I wanted to, but I needed a keyboard so I rebooted the computer with a keyboard and mouse the second time, only there was no splash screen the second time.

    I can't get into BIOS now since I don't know what I'm seeing.
  8. Did you try what rgd1101 suggested?
  9. I re-seated the video card and the cpu fan runs.

    Are there any options that are new I haven't tried? I don't know why I'm no longer getting POST.
  10. OK, power the system down. Disconnect all power sources (power cable, monitor, powered speakers , etc). Open the case. Remove the video card and set aside. Remove the mobo battery, press the power button to discharge any residual power. Wait at least 5 minutes. Put battery back. Reconnect all power sources. Do not install video card. Use integrated video only. Restart.
