I recently swapped out my GPU, and now my PC is totally unresponsive—it won't turn on at all. I tried using a paperclip on the power supply connector, and it works, but it won't start when connected to the motherboard. I've tried removing one RAM stick and the new GPU, and even turned it on using just the integrated graphics from my CPU with the cooler attached. None of these efforts have worked. I also cleared the CMOS, but that didn't help either. The power switch is connected to the motherboard, and I tried using the button directly on the motherboard as well. Could it be that my motherboard is dead?

It’s possible you might have accidentally discharged something while installing the new GPU. This can sometimes happen, and it could lead to the motherboard getting damaged. Make sure all the power connectors are secure, and check for any visible damage on the motherboard. If there’s no luck getting it to power on again, you might need to look into a motherboard replacement.
It’s unusual for a PC to go completely dead just from changing the GPU unless something went wrong during the swap. Did anything seem off while you were replacing it? If all else fails, try disconnecting non-essential hardware and see if it powers on with just the bare minimum—like the CPU and one stick of RAM. If still no luck, it might be a sign that the motherboard has suffered some kind of damage.
That sounds pretty frustrating! First off, make sure the GPU power connectors are properly plugged in. If you've got a different GPU, I'd suggest trying to swap back to the old one just to see if it works. But if you’ve already sold it, then check if everything is still connected well on the motherboard, as sometimes when you swap components, things can come loose. Also, are the motherboard lights on or do the fans spin up at all?
