I just get a new gamer desktop pc, I think I'm having a issue with the GPU, when I turn on the pc I get no signal in my monitor, it seems like everything is working even the GPU because it displays a blue light and the fans rotate ,the only way I get signal is when I unplug and plug back the power cables from the GPU, but when I shut down the pc and power on again I got the same issue, can someone please help me with this??
