I have verified that the power switch works (I also tried jumpstarting with screwdriver tip to no avail), that the power supply is not faulty (I got the same issue when using a PSU that is known to work), and that the CPU is seated properly ( I reseated it). I am completely stumped. The PC was recently transported with items crammed inside of them but they shouldn't have shorted anything as they were plastic and paper. I also tried replugging all of the PSU cables to no avail. Any help is appreciated, thanks.
