What to Do:

3. Scan for Malware and Viruses
Malicious software can cause crashes, slowdowns, and unexpected restarts.
Recommended Tools:
Windows Defender (built-in) Malwarebytes or Bitdefender for added protection
Run full scans weekly and update your antivirus software regularly.
4. Prevent Overheating
Excessive heat can cause sudden shutdowns or hardware damage.
Tips:
Keep vents and fans clean using compressed air Don’t place laptops on soft surfaces (like beds or cushions) Use a cooling pad or external fan for laptops Monitor temperature with apps like HWMonitor (Windows) or Mac Fan Control
SEO Tip: Use long-tail keywords like “how to keep my laptop cool” for better organic search ranking.
5. Upgrade RAM and Storage If Needed
Running out of RAM or using a failing hard drive can lead to performance issues and crashes.
Signs You Need an Upgrade:
System frequently freezes under load Programs crash or fail to open Storage drive is consistently over 90% full
Upgrade to SSD for faster performance and more reliability.
6. Check for Hardware Failures
Failing RAM, graphics cards, or hard drives can cause recurring crashes.
How to Check:
Run Memory Diagnostics (Windows): Search “Windows Memory Diagnostic” Check Disk Health: Use chkdsk (Windows) or Disk Utility > First Aid (Mac)
Consider replacing hardware if errors are detected.
7. Disable Problematic Startup Programs
Too many apps launching at startup can slow down or crash your computer.
For Windows:
Open Task Manager > Startup tab Disable unnecessary programs
For Mac:
Go to System Settings > General > Login Items Remove apps you don’t need at startup
8. Avoid Overloading the System
Running multiple high-memory applications at once can crash systems with limited RAM.
Best Practices:
Don’t run too many tabs or apps simultaneously Use lighter versions of software (e.g., browser extensions instead of full apps) Close background apps when gaming or editing videos
9. Perform Regular System Maintenance
Routine maintenance prevents long-term problems.
Recommended Schedule:
Weekly virus scan Monthly disk cleanup Quarterly driver update Annual thermal paste reapplication (advanced users)
10. Backup Your Data and Create Restore Points
Even with prevention, crashes can still happen. Be prepared.
Windows:
Use System Restore and File History Set automatic restore points after major updates
Mac:
Use Time Machine to create regular backups
Keep Your Computer Crash-Free
