Hey. I've been wanting a gaming pc for a while now, so last christmas I was able to buy all the parts (Rx 570 4gb, ryzen 3 2200g, segate barracuda 1tb, 8 gb ram, 550 watt psu.) My sister built the pc. When she turned it on, only the fans and lights would turn on. If you plugged it into a monitor, there'd be no visuals. We replaced the Cpu and motherboard to no avail. we also tried her Pc's ram and psu and it still did not work properly. Recently (A week ago) I thought maybe the Hard drive was broken and that it caused there to be no visuals. I need help to know if this is true or not.
