  1. and i use stabimatic servo motor stabilizer to ensure smooth supply of power to my pc
  2. mostly psu issue.i would reccomend to check that gpu in others pc.
  3. step 1) try a different PSU
    if step 1 doesn't work your PSU is fine
    if step 1 works your PSU is dead

    step 2) try a different GPU
    if step 2 doesn't work you have a dead MB socket
    if step 2 works you have a dead GPU
  4. i dont have other setup to check gpu,any software to check psu?
  5. no software to check psu
