I just build my first pc. Specs being Amd Ryzen 3 1200 cpu, asus Gtx 1050 ti gpu, Asrock320M-HDV motherboard, evga 450 psu, 2 x 4gb gskill ddr4, western digital blue 1tb harddrive.
The power led turns on, the hdled doesn't, all the fans are spinning, but the monitor only gives me a no signal.
I am new to this and have no idea what to do.
Thanks in advance.
