How to Fix a Laptop Not Working Properly

The very first step when your laptop is not working properly is to perform a full system restart. Many temporary glitches, stuck background services, and memory leaks clear up automatically once the operating system reloads completely. Keep in mind that simply closing the lid might put your laptop into a low-power sleep mode rather than fully rebooting it, so use the proper shutdown menu instead.

If the sluggish behavior continues after a restart, you need to check which apps are consuming your system resources. Press Ctrl + Shift + Esc to open Task Manager, then click on the CPU, Memory, and Disk column headers to sort processes by usage. If an application or background service is constantly utilizing 90 to 100 percent of your resources, right-click on it and select End task. Identifying rogue background programs prevents your CPU from overheating and stops your system from freezing up during critical workflows.

Outdated operating system builds and corrupted hardware drivers are major culprits behind system instability. Manufacturers regularly release patches to fix bugs that cause laptops to lag, disconnect from Wi-Fi, or display graphics errors. To check for pending updates on Windows 11, open Settings > Windows Update and click Check for updates. Allow your laptop to download and install any available security patches and cumulative updates, then restart when prompted.

Beyond system updates, your graphics, audio, and network adapters need current drivers to communicate correctly with your hardware. Navigate to Settings > Windows Update > Advanced options > Optional updates to see if hardware manufacturer drivers are waiting for installation. Alternatively, visit your laptop manufacturer's official support website to download the latest certified drivers for your specific model number. Avoid third-party driver updaters, as they frequently install incorrect files that worsen system stability.

Corrupted system files can cause random application crashes, blue screen errors, and general system unresponsiveness. Windows includes powerful built-in command-line utilities designed to scan your storage drive and repair damaged system files automatically without requiring third-party software tools. To run these tools safely, type cmd in the Windows search bar, right-click on Command Prompt, and select Run as administrator.

First, type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter to repair the Windows system image. This process may take several minutes as it connects to online Microsoft servers to replace damaged components. Once that completes, type sfc /scannow and press Enter to scan all protected operating system files. If the System File Checker finds integrity violations, it will automatically swap corrupted DLL files and registry keys with healthy cached copies. Restart your laptop once the verification reaches 100 percent.

Laptops equipped with traditional hard drives or nearly full solid-state drives often experience severe slowdowns because Windows lacks enough virtual memory headroom to manage temporary swap files. Ideally, you should maintain at least 15 to 20 percent of free space on your primary C drive. Open Settings > System > Storage to analyze what is taking up space, and use the built-in Disk Cleanup tool or Storage Sense to remove temporary installation files, system cache, and items sitting in your Recycle Bin.

In addition to storage limitations, too many programs launching automatically when you turn on your laptop can overwhelm your RAM right from startup. To fix this, go to Settings > Apps > Startup in Windows 11 or open the Startup tab inside Task Manager in Windows 10. Review the list of applications and toggle off any non-essential background programs such as game launchers, cloud sync tools, and media helpers. Disabling unnecessary startup apps drastically shortens boot times and keeps your baseline memory consumption low.

Malware, adware, and background crypto-mining trojans can quietly hijack your laptop processing power, causing fans to spin constantly and applications to freeze without warning. Even if you practice safe browsing habits, malicious scripts can infiltrate your system through compromised downloads or unpatched browser extensions. To run a thorough safety inspection, open Windows Security by searching for it in the taskbar, then click on Virus & threat protection.

Select Scan options and choose Microsoft Defender Offline scan. This specialized diagnostic routine restarts your laptop into a secure standalone environment before the full operating system loads, allowing it to detect and eliminate stubborn rootkits and deep-seated malware that standard active scans might miss. After the scan finishes, review your installed browser extensions and remove any unfamiliar toolbars or add-ons that could be injecting unwanted scripts into your web traffic.

If you have tried all the previous troubleshooting steps and your laptop is still not working properly, a more drastic software recovery method may be necessary. If the performance issues started recently—perhaps right after installing a new application or running a patch—you can roll your system back using System Restore. Type Recovery in the Windows search bar, select Open System Restore if you have restore points enabled, and choose a date prior to when the problems began.

When restore points are unavailable or fail to resolve the underlying instability, performing a clean reset is the most reliable option. Go to Settings > System > Recovery and click Reset PC. You can choose to keep your personal files while wiping installed applications and system settings, or choose a complete factory wipe if you intend to start fresh. This process reinstalls clean system files and eliminates lingering driver conflicts that resist normal troubleshooting methods.
