No graphical output, no onboard graphic, but system running

By harlekin ·
Hi everybody, I have a delicate question.

So last Monday my PC suddenly turned off and when I turned it on again it smelled a bit burnt. I couldn't start it up afterward so I thought either the motherboard or the power supply is broke.

I ordered a new motherboard as well as power supply and installed both. Everything seemed to work nicely, system running, fans turning but there wasn't any graphical output. I both tried VGA and HDMI plugs. Sucks!

Now I think that I would have to re-install the graphic card, but I can't find a way to do that, since my the new motherboard has no integrated graphic chip.

Does anyone have an idea on how to proceed?

My specs:
Gigabyte GA-970A-DS3P rev.1
EVGA GTX 760 SC 4GB
Corsair DDR3 2133 MHz 16 GB
AMD FX-8320

Thank-you!

Troubleshooting

by Marc Erickson In reply to No graphical output, no o ...

I assume that you mounted the video card in the top slot next to the heat sink (says PCIEX16 at the left end of the slot)? It should put out video if the hardware is good and the card is compatible.

Try the card in the other slot (PCIEX4). If you get video, the first slot is bad and RMA the Gigabyte M/B. Try the card in another computer that is working properly. You may have to go into the BIOS and change settings to get video - consult the M/B manufacturer's manual. No need to install the card (in Windows) on the 'new' machine - if you get video during the POST, the Gigabyte M/B is bad - RMA the M/B.

Try a video card that is known to be good in the Gigabyte M/B's PCIEX16 slot and in the PCIEX4 slot. If there's video, the video card is bad. (Sometimes a power surge will damage everything - that may be what happened to you).

Finally, some hardware just won't work together. I'm currently going through that with my Dell server. If you have to buy a new video card, try to get it from a store that will allow you to change it without cost for a different card if the card won't work in your Gigabyte computer.

Good luck.

General Video Installation Info

Marc's advice looks good. Something to add to it...

You mentioned that your new motherboard has no on-board video. This should not be an issue, since Windows will automatically load generic VGA (low-res) drivers so that you have something work with until card-specific drivers are installed.

FYI: If your motherboard does happen to have on-board video and a discrete video card appears to not be working, then the BIOS possibly needs the on-board video disabled first. After that, the computer would behave in the manner as described above.
