Windows Tools to Try Before Taking Your Laptop to a Repair Shop

If your Windows laptop starts running slowly, freezes for no reason, or fails to boot properly, the first thought you might have is to take it to a repair shop. But, before that, you can try a few things at home.

It is worth noting that there are a few inbuilt Windows tools, such as System File Checker, Windows Memory Diagnostic, and Check Disk, that can help diagnose and sometimes fix common laptop problems without needing professional help.

Take a look at these five useful Windows tools worth trying before taking your laptop to a repair shop.

Windows Tools for Common Laptop Problems

1. System File Checker (SFC) and DISM

Corrupted or missing Windows system files are a common cause of crashes, slow performance, and strange errors. Two inbuilt command-line tools, DISM and System File Checker (SFC), can help repair these files.

How to use them:

• Search for Command Prompt, right-click it, and select Run as administrator.

• First, run the DISM command to repair the Windows image: DISM /Online /Cleanup-Image /RestoreHealth

• After it finishes, run the System File Checker: sfc /scannow

• Restart the laptop once both commands are complete.

Note: DISM repairs the component store that SFC uses, so running DISM first usually gives better results. This process can fix many issues caused by corrupted system files and is one of the most effective first steps before considering a repair shop visit.

2. Windows Memory Diagnostic

If a laptop is randomly crashing, showing blue screens, or closing apps without warning, faulty RAM could be one of the reasons. In these cases, Windows Memory Diagnostic can help users check for memory-related problems.

How to use it:

• Search for Windows Memory Diagnostic in the Start menu and open it.

• Select Restart now and check for problems (recommended).

• The laptop will restart and automatically run the memory test, which usually takes around 10–30 minutes.

• Once the test is complete, Windows will restart normally. To check the results, search for Event Viewer, go to Windows Logs, then System, and look for a "MemoryDiagnostics-Results" entry.

Note: If the tool reports errors, it could indicate a problem with the RAM, which may require hardware attention. If no errors are found, the problem is more likely to be software-related.

3. Check Disk (CHKDSK)

Storage drive errors can lead to slow performance, files not opening, random crashes, or even boot problems. Notably, Check Disk (CHKDSK) tool can scan the drive for file system errors and bad sectors and can fix certain issues.

How to use it:

• Search for Command Prompt in the Start menu, right-click it, and select Run as administrator.

• Type chkdsk C: /f /r and press Enter. Replace C: with another drive letter if users want to check a different drive.

• If the drive is currently in use, Windows will ask whether to schedule the scan for the next restart. Type Y and press Enter.

• Restart the laptop. The scan will run automatically before Windows starts. Depending on the drive's size and condition, it can take anywhere from a few minutes to more than an hour.

Note: The /f option fixes file system errors, while /r checks for bad sectors and tries to recover readable data. If a laptop is showing disk-related warnings or behaving unreliably, running CHKDSK can help identify whether the storage drive is causing the problem.

4. Reliability Monitor

Repeated crashes or apps suddenly stopping can make it difficult to figure out what is actually causing the problem. Reliability Monitor shows a timeline of system failures, warnings, updates, and other important events, making it easier to spot when an issue started.

How to use it:

• Search for Reliability Monitor in the Start menu and open View reliability history.

• Users will see a graph showing the laptop’s system stability over time.

• Click on any date with a red X or yellow warning to see details about the issue, such as an app crash, Windows Update failure, or hardware error.

• Check the timeline to see if the problems started after a particular update, driver installation, or software change.

Note: Reliability Monitor does not fix the problem itself, but it can give users a better idea of what went wrong and when. This can make troubleshooting easier, especially if users eventually need professional help.

5. Inbuilt Troubleshooters

Windows has several inbuilt troubleshooters that can help users find and fix common problems with audio, internet, Bluetooth, printers, Windows Update, and more.These are easy to run and can often fix the issue without requiring users to manually change settings.

How to use them:

• Open Settings.

• Go to System, then Troubleshoot, and then Other troubleshooters.

• Find the troubleshooter related to the problem, such as Internet Connections, Audio, or Windows Update, and click Run.

• Follow the on-screen instructions and let Windows check for possible issues.

Note: Users can also search for specific troubleshooters from the Start menu or use the Get Help app. While these troubleshooters cannot fix every problem, they are a quick and safe first step when dealing with common Windows issues and could save users a trip to the repair shop.
