Alienware M15X Motherboard Replacement

The keyboard controller on my motherboard is acting odd. It keeps inputting the "=" character repeatedly. I tried many possible fixes by searching with Google but I will need to replace my motherboard.

The PN: DELH-40GAB390V-A20M  

CN0WDXH7476703C0001A00 

Model: P08G

It's sporting an i7 with a 989 socket. The part number on the back of the physical board reads...

PCB P/N: DELH 41 AB3900 A00G

PWA P/N: DELH-40GAB3900-A [A white block]

AB390

With all the information above, I am unable to find an identical replacement. Could anyone tell me of a replacement that will be compatible? 

I have pictures of all the hardware and bios screen if needed.

Yes, I tried multiple USB keyboards and I bought a new keyboard for my laptop. It triggers the "=" character repeatedly with the laptop keyboard connected or not.
