graphics card drivers wont install on this computer but installs on other computers

[sibonacci]

MY PC SPECS: motherboard GIGABYTE H97-D3H
cpu:intel I5 4590
GPU: MSI R9 390 gaming x
RAM: 16GB 1600 MHZ CORSAIR VENGENCE
PSU: Raidmax rx-730ss
OS: windows 10 pro 64 bit

my problem started weeks ago i was play games then all of a sudden the video feed cuts but pc stays on, after reboot i perform a GPU burn in test using Furmack, the computer fails the test, I assume either PSU or GPU is dead, I try to update drivers to latest version with clean install, it fails...few days later is swap out my 730W PSU for a 550W psu, drivers still wont install, i assume GPU is dead, next day i swap my r9 390 for my classmate's r9 270x, my r9 390 works perfectly on his computer but the drivers still dont install using the r9 270x, igot my r9 390 back but i still dont have drivers and still cant play games,

im totaly stuck

THANKS IN ADVANCE
