i forgot to mention its not software. its hardware damage. Before the damage exposed metal touched and bridged something on the back of the GPU causing a spark and it to turn off, since then issue been present. I forgot about this until I tried like every single software fix and it didnt work. I cant find any visible damage on the back of the board all I know is it was something near the power connector that was touched.full system spec? include brand and model of the psu
