I'm trying to figure out what wires are live, neutral and ground in my computer power cable. I'm getting some weird readings from the wires.
A - B = 51v
A - C = 117v
B - C = 65v
I'v read a bunch of articles but can't figure out what is what.

Some power supplies have line-to-ground and neutral-to-ground filter capacitors like this picture:
So line-ground and ground-neutral have half of the line-neutral voltage.
I think this is happen in your situation. So my guessing:
Try using neon screwdriver test light or test pens.
