So I just replaced my power supply because I thought that was the cause, but the problem still persists. When I turn my pc on, the monitor won’t receive any signal. So I turn the pc on and off multiple times until finally, the monitor gets a signal. And then, just randomly while I’m doing something on the computer, the monitor will lose signal again. Any help or idea why? I don’t know if it’s the graphics card or not.
