If your mouse or keyboard is behaving strangely on a Windows PC, it can make the computer very difficult to use. Common problems include random typing, wrong characters appearing, the mouse cursor moving automatically, double-clicking issues, lag, or the keyboard and mouse not responding properly. These issues can happen with Bluetooth devices, wireless USB receivers, or wired keyboards and mice. In many cases the problem is caused by simple settings, temporary glitches, driver issues, or even a stuck key on the keyboard.
If you are using a laptop or desktop from Dell, HP, Asus, Acer, MSI, Lenovo, or any Windows PC, the fixes below can help solve keyboard and mouse problems quickly.
Restart the Windows PC
Temporary glitches in Windows can sometimes cause input devices to behave incorrectly.
Open Start Menu, click Power, select Restart.
After the computer restarts, test the keyboard and mouse again.
Restarting reloads device drivers and often fixes temporary hardware conflicts.
Release Stuck Keys Using Your Hand (Powerful Fix)
Sometimes the keyboard starts typing automatically or behaves incorrectly because one or more keys are physically stuck due to dust, pressure, or internal keyboard mechanism issues.
Place your hand gently over the keyboard.
Press multiple keys lightly across the keyboard using your fingers.
Release them slowly and repeat a few times.
This helps release keys that may be partially pressed or stuck inside the keyboard frame. Many users fix random typing or misbehaving keyboard problems instantly using this simple method.
If dust is present, lightly tap the keyboard or blow air between the keys to remove particles.
Turn Off Sticky Keys and Filter Keys
Windows accessibility features sometimes cause delayed typing or ignored key presses.
Open Settings from the Start Menu.
Open Accessibility.
Click Keyboard.
Turn Sticky Keys off.
Turn Filter Keys off.
Turn Toggle Keys off.
These features are useful for accessibility but can cause unexpected keyboard behavior if enabled accidentally.
Reconnect Bluetooth Mouse or Keyboard
If you are using a Bluetooth keyboard or mouse, connection issues can cause lag or random disconnections.
Open Settings.
Open Bluetooth & Devices.
Turn Bluetooth off.
Wait a few seconds and turn Bluetooth back on.
Remove the keyboard or mouse from the device list.
Pair the device again.
Reconnecting refreshes the Bluetooth communication between the device and your PC.
Check Wireless USB Receiver
Wireless keyboards and mice that use a USB receiver dongle may stop responding due to interference or loose connections.
Remove the USB receiver from the computer.
Wait a few seconds.
Insert the receiver into another USB port.
Restart the PC and test the device.
Also make sure the keyboard or mouse battery is not low.
Test Wired Keyboard or Mouse USB Ports
If you are using a wired mouse or keyboard, the USB port itself may be the problem.
Disconnect the keyboard or mouse from the USB port.
Plug it into another USB port.
Avoid using damaged or loose ports.
Testing the device on another computer can also help confirm if the hardware is faulty.

If the issue continues, reinstalling the device drivers can help fix corrupted driver files.
Open Device Manager.
Expand Keyboards.
Right-click your keyboard.
Click Uninstall Device.
Restart the computer and Windows will automatically reinstall the driver.
Repeat the same process for the mouse.
Expand Mice and other pointing devices.

Conclusion
Mouse and keyboard problems in Windows can happen with Bluetooth devices, wireless USB receivers, or wired peripherals, but most issues are easy to fix. Restarting the PC, releasing stuck keys, disabling Sticky Keys and Filter Keys, reconnecting Bluetooth devices, updating drivers, and checking USB ports can solve most problems quickly. If the issue still continues after trying these fixes, the keyboard or mouse hardware itself may be faulty and may need replacement.
