A Deep Dive into Common Computer Problems & Their Fixes
Your computer is usually your trusty partner—until one day it decides to overheat, ghost your Wi-Fi, or crash mid-project. Let’s decode four common tech headaches, their root causes, and the steps you can take to fix them before you call in backup.
1. Laptop Overheating
Why does it happen?
- Dust buildup blocks vents
- Fans wear out or can’t keep up with high-performance tasks
- Poor airflow (using it on a bed or couch)
Fix it:
- Use on a hard, flat surface; consider a cooling pad
- Clean vents/fans with compressed air
- Close background apps that hog CPU/GPU
- Reapply thermal paste (advanced fix, best for a technician)
2. Wi-fi Keeps Disconnecting
Why does it happen?
- Router too far or blocked by walls
- Outdated network drivers
- Interference from other devices (microwaves, cordless phones)
Fix it:
- Move closer to the router or use a range extender
- Update Wi-Fi adapter drivers
- Change your Wi-Fi channel in router settings
- Try a wired connection for stability during critical work
3. Slow Performance
Why does it happen?
- Too many startup programs
- Nearly full storage drive
- Malware or too many background processes
- Insufficient RAM for your workload
Fix it:
- Disable unnecessary startup apps (Task Manager → Startup tab)
- Free up disk space or upgrade to SSD
- Run a malware scan
- Add more RAM if your system supports it
4. Random Crashes or Freezes
Why does it happen?
- Corrupted system files or outdated drivers
- Overheating hardware
- A failing hard drive or faulty RAM
Fix it:
- Update OS and drivers
- Check temps with monitoring software; fix cooling issues
- Run “sfc /scannow” in Command Prompt to repair files
- Test RAM (Windows Memory Diagnostic) and HDD/SSD health
Pro Tip: If repair costs approach half the price of a new system—especially for older machines—it’s often smarter to invest in a replacement.
