Is My Graphics Card Fried? Or Motherboard? Not Enough Power?

bootsdibeer · Nov 20, 2013

I recently was messing with some wires and unplugged my computer by accident. After plugging it back in, the there was no longer any signal going to my monitors from my tower. I opened the case, and noticed two red lights on my GFx card. It seems like everything else was still working, as I could hear the windows login chime when I turned on the computer, but there was no video signal going out.

After googling that issue, it looked like I may have fried the card, so I purchased a new card (The other was pretty old anyway, so this was a decent excuse). After plugging that in, the issue is not resolved and I still cannot see any video.

All I can think of is I don't have enough power coming from my PSU (520W), or my motherboard is busted. I did recently install some additional fans, but that was about a month ago and I hadn't had any issues since then. I don't really have a backup computer to test parts on.

Anyone think of anything else I can try? If not I guess I'll have to take in the tower to a computer shop, something I've been able to avoid for a long time. Thank you.

Please post the brand and model number of you components (MB, PSU, etc.) and your version of windows. It looks like your card requires one 6 pin power connector. Did you use it? Is the card in the correct slot and fully seated down into it? If you CPU has integrated graphics, did you select the video card solution for your graphics in the bios?

I plugged the 6pin into the card, and made sure it was seated as flush as possible. However, there were no lights that came on the card, and the fan was not running. All the other fans in my tower were running at that time. I did not do anything with integrated graphics, as I don't think there are integrated graphics in my components.

The power supply is a few years old, so could that be the issue?

That's not very old for a PSU; it has plenty of wattage for either card and it's a quality unit. Since you are receiving power, the fuse on the PSU is good. It's possible the slot on the motherboard has failed. try putting the card in your other pci-e slot.

I got my new card working. I used the other pci-e slot, and it wouldnt work at first.

It looks like the issue was the card is having troubles being fully plugged in the motherboard, as the card may not be shaped perfectly. The part of the card that plugs in and is right next to backside of the tower was being slightly blocked, not letting it be fully plugged in.

I beat on the part that I screw the video card on to the case, and it seems to be working fine now. The other card and pci-e slow may even be working. Could this be my motherboard warping or some other issue I need to look into?

If your motherboard is screwed in at all mount points, it's more likely a case construction issue, either at design or tolerance levels in production.
