    Thats totally fine i was just kidding :) doesnt matter if u have the alienware with GTX 1060/1070 or 1080. The motherboard is the same and according to the schematics the two Capacitors missing ( 539 & 542 ) they both are 100U_25V each . Just search that on ebay you will find alot there .Just order the mosfets & missing capacitors and its better to replace the mosfet right next to the fried one ( atleast i would do that )
    Edit: Sorry forgot to tell you . YES both MOSFETS are same no need to worry about that just order the part number i gave you for both MOSFETS & CAPACTORS and install them and hopefully you will bring your system back to life :) ( atleast inform me i would love to hear that news xD )

    the original problem was that exactly capacitor i believe,the other problems were made by pseudo electronics guys, one burn the two mosfets, perhaps trying to bridge them, i dont know, the missing pieces was another guy.... so i try to fixing by myself, watching youtube videos, and i think i found the problem in that capacitor, but i have no clue how to order or ask it, also i cant desolder right now cause my pencil solder iron has no power enough, im getting a new one

    is that capacitor shorted to ground ? if so then try removing the capacitor and check in continuity mode ..if still beeps then shorted otherwise it is fine
