So my PC had been sitting in the car for a while and was pretty cold when I brought it inside. I was plugging in the power under the desk and the moment it made contact I heard what sounded like a loud pop noise from the case, and now it won't turn on, no sign of power whatsoever. Anybody know what would cause that? Any way to revive my PSU or can I assume it's dead if it doesn't work when it warms up? Tried a different power cord, no go.
