My computer is a Dell optiplex 3020 I turned it into a gaming pc and took the original Dell PSU out and put a 80 plus bronze 600w one inside and put a Rx 570 I used for a couple hours till it turned off when I launched apex legends and hasn't turned back on I have replaced the PSU and motherboard and still no display from either the gpu or on board graphics
