The Voltage Selector Switch may be on the right switch, but it’s a good idea to check. It is a button on the back of the desktop computer. The switch lets you balance the internal circuit of your device with the voltage coming in. If it is set wrong, it could affect how your system boots.

Check all Connections

Check to see if all the cables, ports, and adapters are properly connected. Also, make sure that both ends of the power and video cables are securely attached.

If the cables work, make sure you’re using the right source for the input.
If everything looks good, there might be a problem with your monitor. First, try hooking up another screen to your computer.

Check for loose connections, broken cables (VGA, HDMI, DVI, Thunderbolt, etc.), or bad adapters (for example, DVI to VGA)

Turn off your computer and unplug all of its extra parts.
Now, turn it back on and see if the problem is still there.
If there isn’t a problem, plug in each peripheral device one at a time to see which one might be causing it.
