Computer Help Please! My computer keeps crashing after installing new GPU.

If that were true they'd get bsod instantly instead of screen shutting down.

though they could use a debugger but not sure if they know how to work it.

The best way to test it out, is to put different graphic card, load the game and see if it does anything.

Bsod may occur if there is a failure of the CPU or CPU power section. It may be just a motherboard power section rippling all around and not giving the constant voltages and power.
XFX Radeon 560 RX drains all its power from the PCIE slot, and it could drain up to 120 W peak and 100W sustained.

^this is exactly what I was gonna ask about.

Is the card getting sufficient power? GPUs are pretty power-hungry and the pcie slot they're put in matters, although it'd be impossible to have put it into one of the pciex1 slots, as your motherboard appears to only have a single pciex16 slot for a gpu.
