Question details
The user needs to troubleshoot and fix Windows system errors that are preventing normal computer usage.

- Product
- Windows OS
- Device & OS
- Windows
- Scenario
- The user is unable to operate their computer normally due to systemic software, driver, or system file errors.
- Observed behavior
- The computer experiences severe errors, freezes, or crashes, potentially caused by corrupted files, conflicting software, or failed updates, rendering it unusable.
Before proceeding with advanced system repairs, ensure you have your Windows account password ready, as some startup options (like Safe Mode) may require it instead of a PIN.
Boot into Safe Mode to Isolate Software Conflicts
Safe Mode loads Windows with a minimal set of drivers and background programs, making it easier to identify and remove problematic software or updates.
If an incompatible driver, startup program, or recently installed application is causing the system to crash, Safe Mode prevents it from launching.
Once in Safe Mode, you can safely uninstall problematic software, roll back drivers, or perform system restores without interruption.
Click the Start menu, select the Power icon, then hold down the Shift key on your keyboard while clicking Restart.
After the computer reboots to the blue Choose an option screen, select Troubleshoot, then Advanced options, and finally Startup Settings. Click Restart.
Once your PC restarts, a list of options will appear. Press the 4 or F4 key on your keyboard to start your PC in Safe Mode.
In Safe Mode, open Settings > Apps (or Control Panel) to uninstall any recently added applications or updates that might be causing the error.

Repair Corrupted System Files with SFC and DISM
Built-in Windows command-line tools can scan the system directory and repair missing or corrupted files that often cause system-wide errors.
Install Pending Windows Updates and Drivers
Updating your system ensures that you have the latest bug fixes, security patches, and hardware drivers provided by Microsoft.
Switch to a Lightweight Office Suite to Minimize System Strain
Heavy applications can sometimes contribute to system crashes, slow performance, and Windows errors. WPS Office is a free, lightweight, and highly optimized alternative to Microsoft Office that runs smoothly even on older hardware, minimizing the risk of system freezes.
- 1. Download the installer: Visit the official WPS website and download the free setup file.
- 2. Run the setup: Double-click the installer and follow the lightweight setup wizard.
- 3. Open and create: Launch WPS Office immediately and open any existing Microsoft Office document to begin working.

Frequently Asked Questions
Will running SFC or DISM commands delete my personal files?
No. The System File Checker (SFC) and DISM tools only scan and repair built-in Windows system files and core components. Your personal documents, photos, and third-party applications will remain completely untouched.
How do I perform a clean boot in Windows?
Press Win + R, type 'msconfig', and hit Enter. Go to the Services tab, check 'Hide all Microsoft services', and click 'Disable all'. Next, navigate to the Startup tab, open Task Manager, and disable all startup items. Finally, restart your computer to boot with minimal interference.
What should I do if a recent Windows update caused these errors?
If your computer started experiencing severe issues immediately after an update, boot into Safe Mode. Navigate to Settings > Update & Security > Windows Update > View update history, click 'Uninstall updates', and select the most recent patch to remove it.
Why does my computer randomly freeze and require a hard reset?
Random system freezing can be caused by faulty hardware components (such as failing RAM or an aging hard drive), overheating, outdated graphics drivers, or deep system file corruption. Isolating the issue by using Safe Mode can help determine if it is software-related rather than a hardware failure.
