Try going into your BIOS and turn Safe boot mode off, this happened to me with my HD7870 and it fixed the problem

Here's the thing though. After I installed the power supply, I installed the graphics card right into the x16 slot with the PCI express power connector. I did not disable on board video before installing the card. Then, we took out the graphics card and disabled the on board graphics.
I'l try turning safe boot mode off.

Do you know what your motherboard is called? It should say somewhere in the middle of the motherboard

It won't do anything bad, your system doesn't recognise the GPU so it won't allow it to work

Could it be the system, Acer?

You asked me if I enabled Legacy support.
Am I supposed to enable it or disable it?
