If your operating system (OS) is acting abnormally, there are a few things you can do to try and fix the issue:
1. Restart your computer: This can clear up any temporary issues or memory leaks that might be causing the abnormal behavior.
2. Check for updates: Make sure your operating system and programs are up-to-date. Updates can sometimes include bug fixes and performance improvements.
3. Run a virus scan: Malware can cause abnormal behavior in your OS. Make sure your antivirus software is up-to-date and run a full scan.
4. Check for conflicting programs: Some programs can conflict with each other and cause abnormal behaviour. Try uninstalling any recently installed programs or ones that you suspect may be causing the issue.
5. Restore your system: If you recently installed a program or made changes to your system, you may want to try restoring your system to an earlier point in time. This can undo any recent changes and restore your system to a working state.
6. Reinstall your OS: If all else fails, you may need to reinstall your operating system. Make sure you have backed up all of your important files before doing this, as it will erase all data on your computer.
If none of these steps solve the issue, it may be worth seeking help from a professional or the manufacturer of your computer.
