pc won't recognize GPU or slot after accidental unplug while on?

[Bobanater]

Hi everyone. I'm new to the forums here, but I registered because I'm having a problem with my PC and thought it best to ask for support about it here. Ok so, heres the story. I have a pc at home with a nvidia geforce gtx 760 gaming HD card. Well, my dad decided to open the case and install a new sound card, WHILE the pc was ON, and he accidentally dislodged the Graphics card from the pcie slot. Now, the PC does still turn on, and has onboard video via nvidia geforce 6100 chip (yes, its an older prebuilt gateway gm 5084 pc, haha). the PC does still power up and boot up to the windows desktop using the onboard graphics, but not from the pcie slot. The bios is set to boot from pci-e. I have another pc with a pcie gfx card that I use for home entertainment and it had similar power requirements-my pc with the failed card could easily power this other card. But this other card doesn't work either. I have tried resetting the bios clearing the CMOS, breadboarding, etc...but nothing. the only thing I havent yet tried is the unplugged card in my other working pc to see if the card still works and rule that out. But Im a bit afraid of doing that and risking damaging my other working pc? is it possible that he shorted the card out and the actual slot too? if so, is there any way i can fix it, or is my mobo pretty much toast regarding PCIE slot connectivity?

huge thanks to anyone who can help or give me some more insight to how to solve this problem! I'd really rather not have to buy any new components, since I don't really have the budget to squeeze any money from right now.

Do your MB have other pciex16 slot? but I think it does not has other one.

I think your dad may use too much force to remove the GPU so that he killed the gtx760 ( maybe). But if you don't try it, and nobody will know either the MB ( pciex16 slot) or GPU is gone, or something else. Or may go to local PC shop ask for help.

But if he killed it, then wouldnt the fans not spin up and the pc fail to post? the fans still spin up and the system automatically reverts to my onboard, even though the bios is set to pci-e. I could be mistaken, but can it mean that since the fans still spin on the card, that it could be ok? I will do a complete diagnosis later on tonight ( psu, mobo, video card) I will take the video card out and test it on my currently working computer with pci-e, and if it works then i can rule out the card. Then I'll take apart the psu on the old machine and switch it with my current working machine, and if it fails to boot up on that, then I'll know it's likely the psu that is toast. then the final test will be to put the newer machine's psu and original video card back into the pc that was forcibly disconnected, and see if it boots up with it. that way i'll know that the mobo is still alright and I'll just need a new psu. Hope I can figure it out and help someone else on this forum who's experienced a similar problem. Though, I have to admit, at this current point in time, any chance of a positive prognosis seems slim.

The fan still spins, that means the gpu got power. You need more test before you know it is fine or not. But from what you said when you install the gpu and boot the pc, it automatically reverts to my onboard iGPU, that sounds like the GPU has problem, or the pcie slot has problem, because the pc can't get signal from the GPU so that it switch to the onboard iGPU.

I was able to determine that it is the motherboard. I pulled the graphics card and power supply out and put them both in another computer that works, and both powered up just fine, the working pc recognized the card and booted up into the OS easily, and the power supply was still working. So that leads me to believe that it is the motherboard pcie slot that shorted out, since none of the other expansion slots (that computer- a gateway gm5084 with foxconn c51gu01 motherboard, has 1 pcie x16 slot, 1 pcie x1 slot, and two pci slots. none of them are working, so that leads me to believe that the board is shorted in that section. I'd rather not replace it but it looks like I will have to.
