Use the built-in disk cleanup utility or third-party software to clean up these files. Remove any unused or unnecessary programs from your computer. They can take up valuable disk space and potentially conflict with other software.

Consider moving files that you don’t frequently access to external storage devices or cloud storage services. This can help free up some room on your computer while still retaining access to your files.

Duplicate files can consume unnecessary storage space. Use specialized software or manual methods to identify and remove duplicate files, freeing up storage space.

3. Update Your Computer

One of the top laptop troubleshooting tips is to update your computer. Outdated software can lead to compatibility issues and performance problems.

Make sure that your operating system is always up to date. You should also check your drivers. Outdated or incompatible drivers can cause issues.

Visit the website of your computer manufacturer or the specific hardware component manufacturer to download and install the latest drivers for your system.

Check all your other applications and programs. Many software programs have built-in update features. Or, you can check the software’s website for the latest version.

Don’t forget your firmware. Firmware is software embedded in hardware components. Visit the manufacturer’s website for your computer or specific hardware components and check if there are any firmware updates available. Use the instructions given to update the firmware.

4. Check The Heat

Overheating can cause a range of common laptop issues, including random shutdowns, performance degradation, and hardware failures.

Keep an eye on your computer’s temperature using monitoring software and ensure that fans and vents are clean and functioning properly.

Ensure that your computer has proper airflow and is not placed in an enclosed or cramped space. Keep the vents are clear of dust and obstructions. Consider using a cooling pad or additional fans to improve airflow if necessary.

5. Run Some Scans

Viruses and malware can also lead to a broken computer. Run a scan using antivirus software to find and delete any malicious programs.

A failing hard drive can cause various issues, including data corruption, slow performance, and system crashes. Run a disk check utility to scan for and fix any errors on your hard drive.

Dust and debris can accumulate on the cooling fans and heat sinks, reducing their efficiency in dissipating heat. Shut down your computer, unplug it from the power source, and use compressed air or a soft brush to carefully clean the fans, heat sinks, and other internal components.

There are some signs that can point you to the problem with your computer.

Take note of any error messages or error codes you encounter. These messages can provide valuable information about the nature of the problem, allowing you to search for specific solutions online.

Consider whether any specific software applications or processes are consistently running when the problem occurs. Conflicts between software programs can lead to issues. Try closing or disabling certain applications to see if the problem goes away.

Think about any recent changes or updates you made to your computer. This could include installing new software, drivers, or updates, as well as making changes to system settings.

Sometimes, these changes can introduce conflicts or compatibility issues that result in problems. Try to undo recent changes to see if the problem resolves.
