My pc cut out yesterday while gaming, from what I think was an insufficient psu. Since then it will only boot without the you installed.

My pc works fine when the gpu is not installed however when it is, it gives the error "thread stuck in device driver"when I try though the on-board. When I try and use the gpu as the output, nothing happens however all the fans stay working. I think I broke my gpu but would appreciate another opinion
System specs:

Do you think that it could be the psu pci-e cables. It cut out playing a game so they would have been under load?
