Mac keeps shutting down as I try to reinstall OSX

Hey Guys having a bit of a problem here as I did a graphic card fix which worked well btw all 4 LEDs green... I did a HDD erase as to where I could reinstall OSX and now when I try to reinstall OSX the Mac just shuts down ... I've reset ram .... I've smc reset as well to no avail... wondering if within terminal could I do an install to untitled 1

Update (11/12/2016)

Found out by doing a diskUtil list in terminal my Apple boot partition has been wiped out trying to figure a way to restore through terminal

Tell us about this GPU fix please.


Probably a reflow GPU which doesn't really fix the issue. The real fix is pretty much getting another mxm module GPU but that again is like impossible to find a good working one.
