Hi KpopOtaku,

As you have mentioned "Computer works fine but screen says no signal", it indicates the computer's monitor is not receiving any video input. Try the below mentioned steps and check if these steps help:

1. Ensure Monitor is not in power save mode. (Press any key or move the mouse to wake up the system).
2. Disconnect video cable and perform the self-test (if self-test is provided by the monitor manufacturer, refer service manual of the monitor for steps on how to run self-test) and check for the floating box or any pattern on the screen.
3. Check for damages in the video cable (broken or bent pin) and ensure the cable is connected to the correct video source (Port). If cable is found damaged replace the cable.
4. If no damages to cable, ensure correct Input source (VGA, DVI, HDMI, etc.) is selected. Refer to the service manual of the monitor for steps on how check the correct input source.

If the problem persists, reply with the exact model number of the monitor and your computer configuration.
