In case your computer stops working abruptly whilst you're using it, there are a couple of things you can try to resolve the issue before calling a professional for proper attention:
1. First, restart your computer: Sometimes, a simple restart of your computer can resolve issues with freezing or malfunctioning.
2. Check for updates: Ensure that you have the latest updates installed for your operating system, although you need a genuine Windows license to do updates. Also, check other applications installed on your system and make sure they're up to date. These updates may include fixes for known issues that could be causing problems with your computer.
3. Scan for viruses: Run a virus scan to check for any malware or other threats that could be causing problems on your computer. Ensure you have an up-to-date antivirus program installed and run a full system scan.
4. Check for hardware issues: If you are experiencing issues with hardware, such as a malfunctioning keyboard or mouse, try replacing the hardware to see if the changes resolve the problem.
5. Check for damaged or corrupt files: If your computer is experiencing issues with certain programs or files, it may be due to damage or corruption. You can try repairing or replacing the damaged files to see if that resolves the problem.
If you have tried these steps and your computer still doesn't work, you may need to seek further assistance from a specialist, support technician, or computer repair professional. They will be able to diagnose the issue properly and help you find a solution.
