When your computer malfunctions, it can feel like a crisis. While countless issues can arise, many stem from simple causes. Before calling a professional, try these troubleshooting steps:
-
Run a Comprehensive Virus Scan: Launch your antivirus software and perform its most thorough scan. Ensure your antivirus definitions are up-to-date. Consider using a second-opinion scanner (like Kaspersky Security Scan, Microsoft Safety Scanner, or Emsisoft Emergency Kit) for added assurance. Viruses often cause slowdowns, strange behavior, or excessive ads.

-
Update Your Software: Outdated software is a frequent culprit. Prioritize updating your operating system (Windows: Settings > Update & Security; macOS: App Store > Updates). Also, check for updates to your browser and antivirus software, even if auto-updates are enabled. Regularly updating software prevents future problems.

-
Reduce System Bloat: Unused programs slow down your system due to fragmentation and limited storage. Uninstall unnecessary applications (Windows: Settings > Apps; macOS: drag app to trash or use Launchpad's X). Limit browser extensions to essentials. Removing unnecessary files (movies, duplicate photos) also frees up space.

-
Test Your Wi-Fi Connection: For internet issues, determine the problem's source. Connect your computer directly to the router via Ethernet. If the internet works, the issue is with Wi-Fi. If it doesn't, the problem might be with your router or internet service provider. If some devices connect but others don't, troubleshoot those individual devices. If Wi-Fi is the problem, reboot your router and check its settings.

-
Reinstall the Operating System (Last Resort): This drastic step wipes your system clean, removing problematic programs and malware. Back up your data first! Windows offers a reset option in Settings > Update & Security > Recovery. macOS instructions vary depending on whether you have Apple silicon or an Intel processor (refer to Apple support for specific instructions). This is a powerful solution but requires reinstalling all applications and restoring your files.

These tips address common computer problems. If issues persist, consult a professional for further assistance.
