How to enable onboard video after removing GPU?

[m20599]

My computer was working fine when the screen suddenly just went black. I powered it off, and when I powered it back on, there was still no video output and the fan (on the GPU I presumed) was blowing at full speed. I suspected it was a faulty GPU, so I removed it and connected my monitor to the on-board VGA port (after removing the "do not remove" covers on the port). After powering it on there was still no video and the motherboard was beeping - 2 short beeps then a long beep. The beep code for that pattern says, "Unable to initialize video or video card required but not installed". I've read that you cannot enable the on-board video until after removing the GPU, which I have done, but now that it has been removed, how do I enable the on-board video?

Hi:

You can't enable the O/B video because according to the specs, your PC has a first gen Intel quad core processor.

Those require a discrete video card in order for the graphics to work.

Only the 1st gen dual core processors use the O/B video.

You will have to replace the card, and you will need to buy a 'legacy' card.

Nothing newer than an AMD Radeon HD 6xxx series or Nvidia GT 6xx series.

You may want to play it safe and see if you can find the same model card that died on you in used but tested and working condition on eBay.

Thanks, I had an extra GPU laying around (a GT720) that fit and now I have video, but now Windows 10 is giving me a BSOD with the message "inaccessible boot device". That seems to be an unrelated error though, now that we have confirmed it was a faulty GPU...

You're very welcome.

I am rather shocked that a GT 720 worked in your PC, but that is great news.

Worst case scenario is you can reinstall W10 using the media creation tool to create a bootable USB installer.

If you are asked to enter a product key during the installation process, select the 'I don't have a product key' option, and W10 will install and automatically activate once you are connected to the internet.
