Unplug and replug in all main cables 4/8pin cpu, mobo 24 pin, ram, etc.
Remove gpu,
Reset bios,
then try to get it to display on the mobo's intagrated gpu before moving to the dedicated gpu.
Can also make sure your rams in the correct slots and start with 1 stick as well and add em 1 by 1 or switch em out.
