When I turn on power button my cpu and casing fan rotates my pc turns on, but the monitor displays "no signal. My monitor is okay, I've checked its HDMI cable on other devices. I have tried by removing the GPU and connected the monitor HDMI to the main motherboard but still the monitor says no signal. I have also changed the RAM slot but no luck. No I can't turn my pc on. Point to be noted, my power supply is : 450 watt, CPU: Ryzen 3500x. Thanks in advance.
