Default Alienware 18 LA-9332P 3V, 5V short

Hi, as far as I can tell, this board has a short on 3VALW and 5VALW and I am currently stuck on what to do next.

PU100 gets hot when the AC adapter is connected so I assume it's shorted so I have removed it for testing.

QZ1 is grounded on pins 1, 2, 3, 5, 6, 7, 8.

PQ104 pin 5 grounds the DC jack shorting the AC adapter so I have removed it.

PL102 is grounded on pin 1.

PL101 is grounded on pin 1.

PL501, PL502, PL503 and PL504 are grounded when the CPU is in, they are ungrounded when the CPU is removed.

PL201 is grounded.

QZ3 is grounded on pins 1, 2, 3, 5, 6, 7, 8.

PQ201 is shorting the DC jack also and is removed for testing other stuff.

As far as I can tell, 3VALW and 5VALW are shorted somehow and I have come to an end on where to go next so I;m acking the experts on what could be going on. Thanks :-)
