Check Hardware Connections
When your PC boots but the keyboard and mouse do not work, hardware connections might be the problem. Checking these connections is the first step to fix the issue. It helps to make sure everything is plugged in correctly and working well.
Inspect Usb Ports And Cables
Look closely at the USB ports where your keyboard and mouse connect. Dirt or dust can block the connection. Wiggling the cables gently can show if they are loose. Also, check the cables for any signs of damage or wear. Damaged cables may stop the devices from working.
Test With Different Devices
Try plugging another keyboard or mouse into your PC. This test shows if the problem is with the devices or the PC itself. If the new devices work, your original keyboard or mouse might be faulty. Testing helps to narrow down the cause quickly.
Try Alternative Usb Ports
Plug the keyboard and mouse into different USB ports on your PC. Some ports might be damaged or not working correctly. Switching ports can fix connection problems. Use ports on the back of the PC for better power supply and stability.

Restart And Power Cycle
Restarting and power cycling your PC can fix many hardware issues. This includes problems with the keyboard and mouse not working after boot. A fresh start clears temporary glitches and resets connections. Follow these steps to perform a proper restart and power cycle.
Perform A Full Shutdown
Turn off your PC completely. Avoid using the restart option. Press and hold the power button for about 5 seconds until the screen goes black. This ensures all power drains from internal components. Wait 10 seconds before turning it on again.
Disconnect Power And Peripherals
Unplug your PC from the power source. Remove all connected devices like keyboard, mouse, USB drives, and external monitors. This step helps reset the hardware ports. Leave everything disconnected for at least 30 seconds. Then plug the power back in.
Boot With Minimal Devices
Turn on your PC with only the keyboard and mouse connected. Avoid plugging in other USB devices during startup. This isolates the problem and checks if peripherals work properly. Add other devices one by one after the PC boots successfully.
Update Drivers And Bios
Updating drivers and BIOS often solves keyboard and mouse issues after PC boots. Drivers connect your hardware to Windows. Old or missing drivers stop devices from working. BIOS controls the basic functions of your computer. Outdated BIOS can cause hardware conflicts. Keep both updated for smooth operation.
Access Device Manager
Press Windows key + X and select Device Manager. Find keyboards and mice under “Keyboards” and “Mice and other pointing devices.” Right-click the device and select “Properties.” Check for any warning signs. This shows if the driver has problems.
Download Latest Drivers
Visit the manufacturer’s website for your keyboard and mouse. Search for the latest drivers by model number. Download drivers matching your Windows version. Run the setup file and follow instructions. Restart your PC to apply changes. Updated drivers improve device recognition and function.
Update Bios Firmware
Identify your motherboard model using System Information or BIOS screen. Go to the motherboard maker’s support page. Download the latest BIOS version for your model. Follow the instructions carefully to flash the BIOS. Do not turn off the PC during update. BIOS update can fix hardware compatibility issues.

Adjust Bios Settings
Adjusting BIOS settings can fix issues with your keyboard and mouse not working after PC boots. The BIOS controls hardware functions before your operating system loads. Sometimes USB ports are disabled or misconfigured in BIOS. Changing these settings can enable your keyboard and mouse to work properly.
Enable Usb Legacy Support
USB Legacy Support allows USB devices to work in older systems. Without it, the keyboard and mouse may not respond during boot. Enter BIOS setup by pressing a key like Del or F2 at startup. Find the USB settings section and enable USB Legacy Support. Save changes and restart your PC.
Check Usb Configuration
USB Configuration controls how USB ports behave in BIOS. Some PCs disable certain USB ports or set them to different modes. Look for USB Configuration or similar in BIOS. Ensure all USB ports are enabled. If there is an option for USB 3.0 mode, try switching it to USB 2.0 for compatibility.
Reset Bios To Default
Resetting BIOS to default clears any wrong settings causing USB issues. This option is usually found in the Exit menu. Choose Load Setup Defaults or Restore Defaults. Confirm and save changes. Your PC will restart with factory BIOS settings, which often fixes keyboard and mouse problems.
Use Safe Mode For Troubleshooting
Using Safe Mode helps fix keyboard and mouse issues after a PC boots. Safe Mode starts Windows with only basic drivers and services. This makes it easier to find and fix problems.
Try Safe Mode to check if your keyboard and mouse work without extra software. This step helps separate hardware problems from software conflicts. Follow the steps below for clear guidance.
Boot Into Safe Mode
Restart your PC and press the correct key to enter the boot menu. Common keys are F8, Shift + F8, or holding Shift while clicking Restart. Select “Safe Mode” or “Safe Mode with Networking” from the menu. Wait for Windows to load with minimal drivers.
Check Device Functionality
Once in Safe Mode, test your keyboard and mouse. Try typing or moving the cursor to see if they respond. If they work, the problem is likely with drivers or software. If they still do not work, hardware may be the issue.
Uninstall Problematic Drivers
Open Device Manager by right-clicking the Start button. Find the keyboard and mouse devices under “Keyboards” and “Mice and other pointing devices.” Right-click each device and choose “Uninstall device.” Restart your PC normally. Windows will reinstall fresh drivers automatically.
Scan For Malware And Conflicts
Sometimes, a PC boots but the keyboard and mouse do not work. One common cause is malware or software conflicts. These problems can stop input devices from working correctly. Scanning for malware and checking for conflicts helps find the issue. Fixing these can restore your keyboard and mouse function.
Run Antivirus Scans
Run a full antivirus scan to detect harmful software. Malware can block device drivers or cause system errors. Use trusted antivirus software to scan your entire PC. Remove or quarantine any threats found. Restart your computer after the scan finishes. This step often solves input device problems.
Check For Software Conflicts
Software conflicts can stop your keyboard and mouse from working. Some programs may interfere with device drivers. Open Task Manager and close unnecessary programs. Uninstall any recently added software that may cause problems. Update all drivers to the latest versions. This reduces the chance of conflicts and restores device function.
Perform System Restore
System Restore can fix issues by returning your PC to a previous state. Choose a restore point before the problem started. This removes recent changes that may cause conflicts. Access System Restore through Control Panel or Settings. Follow the instructions to complete the process. After restoring, check if your keyboard and mouse work again.
Replace Faulty Hardware
Replacing faulty hardware is a key step to fix your PC when the keyboard or mouse stops working. Sometimes, the problem is not software but broken devices. This section helps you check and replace these parts to get your PC working again.
Identify Defective Keyboard Or Mouse
First, check if the keyboard or mouse is the problem. Look for signs like no response or erratic behavior. Try using the devices on another computer. If they do not work elsewhere, they are likely defective. This step helps avoid wasting time on other fixes.
Test With New Devices
Next, try connecting a new keyboard or mouse to your PC. Use devices that are known to work well. If the new devices function properly, the old ones are faulty. Testing new hardware confirms the source of the issue quickly and easily.
Consult Professional Repair
If you cannot find or replace the problem hardware yourself, seek help from a professional. Repair experts can diagnose and fix hardware issues safely. They have the tools and experience to handle complex problems. This option saves time and prevents further damage.
