Your PC slowing down? Crashing unexpectedly? It might not need a replacement — just a health check. Like a car, computers need regular maintenance to run smoothly. Here’s how to check your PC’s health and performance without technical jargon or expensive tools.

1. Check System Performance with Built-in Tools

Windows comes with several tools that give you real-time insight into how your PC is performing.

• Task Manager (Press Ctrl Shift Esc):
  This is your first stop. Look at the Performance tab to see CPU, Memory, Disk, and GPU usage. If any of these are consistently near 100%, that’s likely why your PC feels sluggish.

  
  • High disk usage? Could be a failing drive or background apps hogging resources.
  • High memory? Too many browser tabs or programs open.

• Resource Monitor (Type “resmon” in Run dialog):
  More detailed than Task Manager, this shows which processes are using disk, network, or memory the most. Great for spotting hidden resource hogs.

• Performance Monitor (Search “perfmon”):
  Use this to log performance over time. Set up Data Collector Sets to track CPU, RAM, or disk usage across hours or days.

  

2. Monitor Your Hard Drive Health

Your storage drive (especially if it’s an older HDD) can be the weakest link.

• Check for S.M.A.R.T. status:
  S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) tracks drive health. Use free tools like:

  • CrystalDiskInfo (popular and simple)
  • HWMonitor (also shows temps and voltages)

  Look for warnings like “Caution” or “Bad sectors.” If you see those, back up your data immediately.

• Run CHKDSK (for HDDs/SSDs):
  Open Command Prompt as admin and type:

  chkdsk C: /f /r

  This scans for file system errors and bad sectors. Note: It may require a reboot to run fully.

3. Keep an Eye on Temperature and Hardware Stress

Overheating can cause throttling (slowing down) or sudden shutdowns.

• Use HWMonitor or Core Temp:
  These show CPU, GPU, and drive temperatures.

  • Normal idle temps: 30–50°C
  • Under load: up to 80–85°C is okay, but above 90°C is risky.

• Clean Dust and Check Fans:
  Physical maintenance matters. Dust buildup blocks airflow. Use compressed air to clean vents and fans every few months.

• Stress Test (Optional):
  Use Prime95 (CPU) or FurMark (GPU) to push your system and monitor temps. Only do this briefly and with caution — it generates heat.

4. Optimize Startup and System Settings

A bloated startup process can make boot times painfully slow.

• Manage Startup Apps:
  In Task Manager → Startup tab, disable unnecessary programs (like Spotify, Skype, or updaters that don’t need to launch at boot).

• Check Disk Speed (Especially for SSDs):
  Use CrystalDiskMark to test read/write speeds. A significant drop from expected speeds could mean your SSD is failing or needs a firmware update.

• Run Windows Maintenance:
  Go to Security & Privacy → Maintenance and click “Start maintenance.” Windows will scan for common issues.

5. Keep Software and Drivers Updated

Outdated drivers or OS versions can hurt performance and security.

• Run Windows Update regularly.
• Update drivers via Device Manager or your PC manufacturer’s support site (e.g., Dell, HP, Lenovo).
• Use Snappy Driver Installer or Driver Booster cautiously — stick to trusted sources.

Basically, checking your PC’s health doesn’t require expertise. Use the tools you already have, watch for warning signs like heat or slow response, and keep things clean — both digitally and physically. A few minutes every month can save you from bigger headaches later.
