1. First, check to make sure that the mouse or keyboard is connected correctly. If the mouse is wireless, ensure that the batteries are inserted correctly and that the receiver is properly plugged in to the computer.
2. If using a USB mouse or keyboard, make sure the USB cable is connected securely to the correct port on the computer. Unplug and then plug it back in to make sure it is connected properly.
3. Check the mouse/keyboard properties in the Control Panel. Go to the Mouse or Keyboard section, select the device and check the properties to make sure all the settings are correct.
4. Try connecting the mouse/keyboard to a different port on the computer. Some ports may not be working correctly, and plugging into a different port can help confirm this.
5. If the mouse/keyboard still isn’t working, try uninstalling and then reinstalling the device driver software. Make sure you have the latest version of the driver, you can usually find them on the manufacturer’s website.
6. Check for firmware updates for your mouse/keyboard. Firmware updates are sometimes released to improve overall performance.
7. If you are using a wired mouse/keyboard, check the cable for any visible damage or bent pins. Damaged cables can cause connectivity issues and should be replaced.
8. If you are using a wireless mouse/keyboard, make sure the signal strength from the receiver is strong enough. Move it closer to the mouse/keyboard or move the mouse/keyboard closer to the receiver.
9. Make sure there is no interference from other wireless devices near the mouse/keyboard, such as wireless speakers or Wi-Fi routers. Try switching them off and see if the mouse/keyboard starts working properly again.
10. Press all the buttons on the keyboard and move the mouse in all directions to make sure they are all working. If some keys or buttons aren’t responding, they may be stuck or not working properly.
11. Check that the problem isn’t caused by a conflict with another program or device. Disconnect any external peripherals (such as printers, webcams, etc.) and see if the mouse/keyboard starts working properly again.
12. Try using a different mouse and/or keyboard, preferably one that works on a different computer. This will help to eliminate the possibility of a defective mouse/keyboard.
13. If the mouse/keyboard does not appear to be working, determine whether the problem is with the hardware or the software. For example, if the mouse moves but the cursor does not, the problem might be related to the software.
14. Try booting the computer into Safe Mode, as this will help to rule out any software conflicts.
15. There could be a compatibility issue between the mouse/keyboard and the operating system. If possible, try using the mouse/keyboard with a different operating system.
16. If the mouse/keyboard appears to be working but is not responding correctly, try calibrating or adjusting the sensitivity or speed settings. These are usually found in the mouse/keyboard properties panel in the Control Panel.
17. If the problem persists, try resetting the mouse/keyboard to its factory settings. This will usually require a hardware reset button or a software reset utility.
18. If all else fails, the problem may lie in the hardware itself. This would require replacing the mouse/keyboard. The best solution is to contact the manufacturer and ask if they offer any extra help or have any suggestions on how to troubleshoot the issue.
