9. Scan your computer for malware

Malware can sometimes interfere with the normal operation of the keyboard and cause various problems including this one. To make sure your computer is free of malware, scan it. You can also use a reputable antivirus to scan for malware and remove any programs that might be causing your keyboard problems.

Once you've finished scanning, restart your computer and see if the keyboard issue is resolved. If not, you can continue to troubleshoot using other methods.

10. Use the virtual keyboard

If none of the above methods solve your keyboard problem, try using the virtual keyboard on Windows. Here's how to access the virtual keyboard on Windows.

The virtual keyboard is a great way to check if your physical keyboard is the problem. If you can enter text with the on-screen keyboard but cannot with the physical keyboard, the physical keyboard probably needs to be replaced.

11. Do some general fixes

There are a few general fixes for this problem. Run the System File Checker command first to repair corrupted or incorrect system files. This tool scans for corrupted files and replaces them with the original versions.

If you recently downloaded or installed a program, it is possible that the installation did not complete properly and caused your keyboard problems.

To test this, you can do a clean boot. This process starts Windows with only basic drivers and services, allowing you to fix any software conflicts that might be causing the problem.
