Hello, today i started my computer to find that the monitor was just staying black. I unplugged the VGA cord from my graphics card to my onboard graphics and the display turned on. i went to device manager and checked, and it said that my graphics card had reported a problem so it had been disabled. So then i uninstalled it from device manager and searched for hardware changes, so that it would reinstall itself. It did, and said it is running properly. I then turned off my PC and plugged the VGA cord back into my graphics card. Started it up, and the screen is still black. I am now plugged back into my built in VGA slot and am wondering what to do.

Device manager still says it sees my graphics card (AMD Radeon HD 7700), and that it is running properly, but the black screen persists. I tried disabling onboard graphics but i do not see an option in the BIOS to do that, and I don't see the onboard graphics in my device manager.
I reinstalled the drivers to my graphics card and no effect.

UPDATE: I just tried using my old Nvidia geforce 210 graphics card and it also displayed a black screen but there's no way its broken. It worked last time i was using it, and my new AMD graphics card shouldn't have randomly stopped working like this either. Maybe one of my PC settings changed?

UPDATE 2: Okay my apologies, the device manager shows that the integrated graphics card is running and working properly, and does not display the graphics card at all. The name of my onboard and external graphics are very similar and it had me confused.

Could be a faulty PCI-Ex16 slot on the motherboard.

If your monitor has several inputs, like HDMI, DVI, DP, VGA etc. you may have to use the monitors GUI to select the correct input.

Or

If you have by accident set your video output to a mode your monitor can't handle, like 144hz update frequency, that will also give you a black screen. I think you can boot into safe mode and set it to something better in that case.

Hmm it could be a bad pci slot. I would take the card out and examine the pci slot for burn marks anything that might be bent, dust, etc.

Would your answer still be the case?

As I said, it's possible. If your motherboard has another PCI-Ex16 slot, try either card in that slot. Might help if we knew what motherboard you actually do have.

If you have a prebuilt Dell pc, there may be an incompatibility with the motherboard and the gpu. See if you have a BIOS update for your motherboard.

I did a BIOS update earlier, and i think the GPU is compatible because i have been using it for 6 months to a year without problems
