Question Graphics Card not detected after unfortunate incident.

[Funkenz]

Problem:
Graphics card not showing on Device Manager after power outage. Monitor says no signal, the fan is spinning.

---

Hardware and software:
AMD-A6 3650 APU with Radeon HD 6530D
Motherboard Asrock A75M-HVS
4GB DDR3 Generic RAM
500W Cooler Master PSU (RS-500-PCAR-D3)
MSI N550GTX-TI Cyclone II 1GD5/OC (Not detected)
Windows 7 (64) Ultimate SP1
American Megatrends P2.00 BIOS

• I checked for Windows Updates, there were no recent updates.
• Extracted the card, inspected for physical damage, none found. Cleaned card and PCIe slot connectors, also card port connectors. Reseated properly.
• Checked RAM on both slots, cleaned connectors.
• Entered BIOS, made sure PCIe was active, there are no other options in the BIOS.
• Updated BIOS from P1.20 to P2.00. No difference.
• Uninstalled NVidia drivers. Probably a bad idea, now I can't reinstall because the card is not being detected, it was already on the latest drivers (391.35).
• Reseted CMOS using jumper cables on Motherboard.
• I was going to flash the VBIOS but I don't have the knowledge to do so.
• Graphics card declared dead out of frustration, after 4 years of service.
• Installed HD 6530D drivers.

At the moment I have the VGA Monitor connected to the Motherboard VGA port (Radeon HD 6530D), before I had the same VGA cable from the monitor to the DVI port on the GTX550TI through a VGA to DVI adaptor.

I think I have isolated the problem to 3 components:

• Faulty PCIe slot on Motherboard.
• Faulty VGA to DVI Adaptor.
• Physically damaged Graphics Card due to power outage or corrupted VBIOS.

I will get a new adaptor later today, I have no access to another PC to check the graphics card on a different Motherboard PCIe slot, I have no access to another PCIe graphics card to check if the PCIe slot is the problem. So, if anyone has any other idea or advice for me, I'll be very grateful.

Could be the gpu, could be the psu as well. Hard to tell without parts.

Does the gpu fans spin? If it does, it's getting some power from the slot, just not enough from psu to operate. (Not a certain explanation)

Hard without trying the card elsewhere but it is likeliest that it is the card that failed.

Yes, the GPU fan is working. I will get a new PSU and if that fails I guess I will take the GPU somewhere they can test it on a different MB.

Since the system is working, first thing I would do is test the card in another computer before buying a power supply.

Dude i have the same problem too but mine didn't work after I updated my windows(1809) and went to bed the next morning it's showing no signal on my monitor but onboard graphics works. Its also not showing in device manager.

I tried:
Reset CMOS
Tried different RAM
Tried different cable and monitor(monitor and cable work on my ps4 too)
tried different gpu(also tried my current gpu on a different pc and its WORKING)
Tried different MOBO
Went to bios and put pcie as my main display
tried a different PSU

NOTHING WORK!!!

Its like my PC cant detect any pcie/pci
My last suspect now is the cpu but i dont know if a cpu can actually make your pcie/pci not working. I need some CPU expert on their opinion before i buy a new one
