hello. so i was playing gta 5 with my friends. and suddenly my pc turned off. i tried to turn it on but it was on black screen. so i plugged in a speaker into my mother board (gigabyte a320m-h) and i get 1 long and 3 short beeps. so i tried clearing the cmos removing the gpu and put it back in. and now i get 1 long and 2 short beeps which is GPU error. and i dont know how to fix it. my gpu is R9 280x. please help and thank you.
