1. Restart Your PC and Disconnect External Devices
Sometimes crashes happen due to faulty USB drives, cables, or accessories.

- Install all updates
- Update GPU drivers (NVIDIA, AMD, Intel)
- Update Wi-Fi, sound, and chipset drivers
Drivers are responsible for over 50% of BSODs.
3. Run a System File Check (SFC Scan)
Corrupted system files cause Windows to crash repeatedly.
Command
Run this in Command Prompt (Admin):
sfc /scannow
Windows will repair damaged files automatically.
4. Check for RAM & Hardware Issues
Faulty RAM or overheating hardware can cause random shutdowns.
Steps
- Run Windows Memory Diagnostic
- Monitor temperatures with HWInfo
- Clean dust from CPU fans
- Ensure proper airflow
If RAM is defective, replace the bad stick.
5. Scan for Malware or Spyware
Malicious apps can freeze or crash your PC.
Use
- Windows Defender
- Malwarebytes

Always remove suspicious apps installed recently.
6. Free Up Storage Space
Low disk space leads to slow performance and crashes.
Do This
- Delete temporary files

Keep 20% of your drive free at all times.
7. Disable Problematic Startup Apps
Too many startup programs = crashes & lag.

- Disable apps with “High Impact”
8. Check for Third-Party App Conflicts
Apps like:
- Antivirus software
- Optimization tools
- Game overlays
