Hi
ve a dell optiplex 3020 MT and i got a brand new rx 570 4gb mining edition. i replaced the psu to a thermaltake 700w and i use a 24 pin to 8 pin connector for the the motherboard . My computer just works fine but when the GPU is installed the computer turns on, CPU fan is spinning / GPU fans too /the lights are on but no display, nothing shown on the screen. i put the the VGA cable to the convertor and then i plug it into the GPU. the computer turns on but no boot and nothing shown on the screen again . and when i plug the VGA cable into the motherboard it works and i can see the GPU information on CPUZ. .i updated the bios to the latest version that i found on dell website, and put the boot mode on UEFI . i put secure boot OFF and legacy option roms ON? but the same thing happened. so what other ways i can try ? ? Note i m plugging the 8 in the GPU and every other cable is plugging properly.
