If your mouse, keyboard, and monitor are not working, check power supply, connections, hardware, and software. Follow troubleshooting steps to diagnose and resolve these common issues efficiently.
Experiencing issues with your mouse, keyboard, and monitor can be incredibly frustrating, especially when all three stop working simultaneously.
This comprehensive guide aims to help you troubleshoot and resolve these common problems efficiently, ensuring your devices are back in working order as soon as possible.
Common Causes for Mouse Keyboard And Monitor Not Working Issues:
When all three peripherals stop working, it is usually due to a few common causes. Understanding these can help you diagnose and fix the problem quickly. Power supply issues are a frequent culprit. Insufficient power or power surges can affect your mouse, keyboard, and monitor.
Ensuring that your power supply is stable and sufficient is the first step in troubleshooting these issues. Another common cause is faulty connections. Loose or damaged cables can disrupt the connection between your peripherals and the computer.
Checking and securing all connections can often resolve these problems. Additionally, defective hardware components can lead to peripheral failure. Identifying and replacing faulty hardware can restore functionality.
Lastly, software glitches, such as driver issues or software conflicts, can cause peripherals to stop functioning. Updating or reinstalling drivers can often resolve these issues.
Checking Power Supply and Connections:
Before diving into more complex solutions, it’s crucial to ensure that your peripherals are properly connected and receiving power. Verify your power source by ensuring your computer is plugged into a working power outlet and checking all power cables for damage and secure connections.
Reconnect your peripherals by unplugging and replugging your mouse, keyboard, and monitor to ensure they are properly connected.
Inspect the cables for any signs of wear and tear, and replace any damaged cables immediately. Additionally, try connecting your peripherals to different USB or HDMI ports to rule out port issues.
Verifying Hardware Functionality:
If power and connections are not the issue, the next step is to check the hardware. Test your mouse and keyboard on another device to see if they work. If using wireless peripherals, ensure the batteries are fresh and properly installed.
For the monitor, ensure it is turned on and connected to a power source. You can also connect the monitor to another computer or device to see if it displays properly.

Updating and Reinstalling Drivers:
Outdated or corrupted drivers can cause peripheral malfunctions. Updating or reinstalling drivers can often resolve these issues. Access Device Manager on your computer and update the drivers for the mouse, keyboard, and monitor by right-clicking on their entries and selecting “Update driver.”
If updating doesn’t work, uninstall the drivers and restart your computer. The required drivers will be automatically reinstalled by Windows.
Checking for Software Conflicts:
Software conflicts can sometimes cause peripherals to stop working. Identifying and resolving these conflicts can restore functionality. Boot your computer in Safe Mode to see if the peripherals work. This can assist in determining if the problem is being caused by a third-party application.
Use System Restore to revert your computer to a previous state when the peripherals were working. If the issue started after installing new software, try uninstalling it to see if that resolves the problem.
BIOS and UEFI Settings:
Sometimes, the problem can stem from the BIOS or UEFI settings on your computer, leading to your mouse, keyboard, and monitor not working. Ensuring that these settings are correctly configured can resolve peripheral issues.
Press the correct key (typically F2, Del, or Esc) during startup to enter the BIOS/UEFI settings when your machine restarts. Check the peripheral settings to ensure they are enabled, and reset the BIOS/UEFI settings to their default values if you suspect a misconfiguration.

Checking for Hardware Failures:
If the above steps do not resolve the issue, there might be a more serious hardware failure causing your mouse, keyboard, and monitor not working. Identifying faulty hardware can help you decide if repairs or replacements are necessary.
Many computers come with built-in diagnostic tools that can help identify hardware issues. Run these tools to check for problems. Additionally, use external diagnostic tools or software to perform a thorough check of your hardware components.
Advanced Troubleshooting Steps:
If basic troubleshooting doesn’t resolve the problem, you may need to take more advanced steps.
Resetting the System:
- Backup Data: Before performing any major system changes, ensure that all important files are backed up.
- Reset PC: Use the “Reset this PC” feature in Windows to restore your computer to factory settings. This can resolve deep-rooted software issues that might be causing peripheral problems.
Checking for External Interference:
Sometimes, external factors can interfere with your peripherals’ functionality.
- Electromagnetic Interference: Ensure that your computer and peripherals are not placed near devices that emit strong electromagnetic fields.
- Physical Obstructions: Make sure that there are no physical obstructions blocking your peripherals’ connections or signals.
Professional Help:
If you’ve tried all the above steps and your peripherals are still not working, it might be time to seek professional help.
- Contact Technical Support: Reach out to your computer’s technical support team for assistance.
- Visit a Professional Technician: Take your computer to a professional technician who can diagnose and fix the problem.
FAQ’s:
1. Why are my mouse, keyboard, and monitor not working simultaneously?
Simultaneous failure of these peripherals is often caused by power supply issues, faulty connections, defective hardware, or software glitches. Ensure all devices are properly connected and powered, and check for any visible damage.
2. How can I check if my power supply is causing the issue?
Verify that your computer is plugged into a working power outlet and inspect all power cables for damage. Ensure that the power supply is stable and sufficient for your setup. Reconnect your devices to confirm they are receiving power.
3. What should I do if updating drivers doesn’t fix the problem?
If updating drivers doesn’t resolve the issue, try uninstalling the current drivers through Device Manager and then restarting your computer. Windows will reinstall the necessary drivers automatically, which can fix corrupted or outdated drivers.
4. Can BIOS or UEFI settings affect my peripherals?
Yes, BIOS or UEFI settings can impact peripheral functionality. Access these settings by pressing the designated key during startup (usually F2, Del, or Esc), and ensure that the settings for peripherals are enabled. Resetting to default values can also help.
5. When should I seek professional help for my non-working peripherals?
If you’ve tried all troubleshooting steps, including checking power, connections, hardware, drivers, software conflicts, and BIOS settings, and the issue persists, it’s time to seek professional help. Contact your computer’s technical support team or visit a professional technician.
Conclusion
Dealing with the frustration of your mouse, keyboard, and monitor not working requires a systematic approach to troubleshooting. By understanding common causes such as power supply issues, faulty connections, and software glitches, you can take effective steps to diagnose and resolve the problem. Ensuring proper connections, updating drivers, and checking BIOS settings are essential steps. If these efforts do not yield results, seeking professional assistance is advisable.
