Optimizing Desktop PC Startup: Key Troubleshooting Strategies for Data Preservation
Introduction
Encountering startup issues with your desktop can be frustrating, especially when vital files are at stake. If your Lenovo M900 SFF PC (Equipped with an Intel Core i5-6500, 16GB RAM, 500GB storage, running Windows 10) refuses to boot normally, exploring safe and effective troubleshooting options becomes essential. This article discusses potential strategies to restore your PC’s functionality without risking data loss, guiding you through various recovery pathways.
Understanding the Issue
Recently, your computer failed to start past the Lenovo initial screen that prompts: “To interrupt normal startup, press ENTER.” Attempts to interrupt the startup process using Ctrl+Alt+Del temporarily restored the Lenovo screen. Entering the Startup Interrupt Menu revealed some diagnostics:
- The CPU extended test passed without issues.
- Storage diagnostics showed passing SMART status, drive self-tests, and seek tests.
- However, certain tests failed, including the SMART short self-test and targeted read test, with a specific result code: UHD01V012-XLYDOG.
Subsequently, the screen switched to a Windows blue screen, presenting options such as Automatic Repair and Startup Repair. Unfortunately, these repair attempts failed to resolve the issue, leaving your important files unbacked-up and your system in a compromised state.
Recommended Troubleshooting Approaches
Before considering more invasive solutions, it’s wise to explore lesser-risk troubleshooting options. These methods aim to repair your system while preserving your files.
- Boot into Safe Mode via Startup Settings
Accessing Safe Mode can help diagnose and resolve issues arising during normal startup:
- Power on your PC and, as Windows attempts to load, force shutdown by holding the power button.
- Repeat this process 3 times until the Automatic Repair mode appears.
- Select “Advanced options” > “Troubleshoot” > “Advanced options” > “Startup Settings.”
- Click “Restart,” then choose “Enable Safe Mode” (option 4 or 5).
-
If successful, troubleshoot further within Safe Mode, such as disabling problematic drivers or uninstalling recent updates.
-
Use Command Prompt for System Repairs
From the Advanced Options menu, select “Command Prompt.” Here, you can perform key commands:
- Check Disk Utility:
chkdsk /r /f C:(replace C: with your system drive letter). This scans for and repairs disk errors. - System File Checker: `sfc /scannow
