What you’ve come across is one of the more common problems any computer user might face. Frustrating as it may be, PC turns on no display is a very fixable problem.

Part 1: Why Does My PC Turn On But No Display

Now PC turning on but no display or usb issue may be happening for a list of reasons, the more common among them being:

  • Loose connections.
  • Faulty hardware.
  • Corrupt system files.
  • Incorrect display settings.

Part 2: Preliminary Checks for Computer Turns On But No Display Issue

Now, first things first, before we jump into deeper troubleshooting and time consuming fixes, we need to carry out a few preliminary checks to see if the problem isn’t just at the surface. Ideally, this could possibly save you the trouble and the cost of your time.

1. Test If Your Monitor is Working

The first thing you need to check is if the monitor is working or not. If the fault lies with the hardware itself there may not be much you can do on your own, other than take it to a repair store or replace it. Hence, this is a very important check.

Simply check the power light on your monitor, make sure the power plug is connected, and try pressing the power button on the monitor once or twice to see if there is feedback from the LED. If the monitor won’t turn on or if the power light is not responsive try reconnecting the power cord or maybe even try another one if available.

If the monitor does indeed turn on then proceed to the next step, if it does not, your best bet is the nearest computer repair shop.

2. Force Restart PC to Check Computer Turns On But No Display Issue

It’s time to move to the good old-fashioned on and off sequence. Try turning your PC on and if the monitor remains blank, hold the power button of your PC (not the monitor) for 10 seconds. Even if the PC shuts down hold it for the complete duration for good measure.

Holding the power button for an extended time pushes your computer into a force restart which can possibly jolt all peripherals and hardware to life.

If the problem persists, move to the next step.

3. Check Connections and Reconnect Monitor

The next thing on the checklist is to make sure there are no loose connections. Simply unplug everything associated with the monitor, including the power cord, the video cable, and any other relevant wires. Reconnect them all, making sure that they are securely plugged in.

Try powering on the computer to see if the problem has been solved. Otherwise, proceed to check 4.

4. Check and Adjust Brightness

It is possible that you or somebody else might’ve accidentally changed the monitor’s brightness settings. Since these are accessible from the buttons on top of the monitor directly try boosting them from the settings menu there.
