The 8 pin power cable would go into my GPU, but where would the other end go?

I've never used an end like that before.

Those are molex connectors.

They go to your power supply, not to your motherboard.

Don't bother with it. It's only useful if your power supply doesn't have the right plug for your video card.

That's an 8 pin PCI to MOLEX converter. You don't need that. Find an 8 pin connector that is connected directly to your PSU. If you have a modular PSU, you have to plug that cable yourself.

My PSU doesn't have a single 8 pin PCI.

I have a 6 pin PCI and a 2 pin PCI. Would it be OK to combine them to make a single 8 pin PCI?

That's a 6+2 pin PCIe cable. It works for both 6 or 8 pin.

When I installed my GPU I started it with a 6 pin PCIe cable in it's 6 pin power input, then I put my other 6 pin PCI cable into the 8 pin power input. I started my computer and nothing appeared on the screen.

I then tried a different pin PCIe cable input into my different pin slots (can't remember) and I then got a message when I started my computer to plug in a PCIe cable.

I then plugged my 6+2 pin PCIe cable into my 8 pin slot, and my 6 pin PCIe cable into my 6 pin slow and it worked.

But could I have damaged my computer with the first couple of attempts?

I don't think so. What you did was actually not providing enough power for your GPU
