Other ways to check PC health in Windows

1. Performance Monitor

An advanced diagnostic tool built into Windows:

• Press Windows + R, writes perfmon and press enter
• Access the system analysis panel
• Generates automatic performance reports
• Analyzes CPU, disk, network and memory in real time
• You can create custom alerts for specific system events.

2. Checking the hard disk (CHKDSK)

To check for disk errors:

chkdsk C: /f /r

This command searches for bad sectors and recovers readable data. It's useful for disks that are experiencing slowness, read errors, or unusual behavior.

3. System File Check (SFC)

sfc /scannow

This command scans and repairs system files that may be corrupted or damaged. It is especially effective after a system crash or the installation of faulty software.

4. Antivirus and security

• Use Windows Defender or a reliable antivirus
• Perform a full scan every week
• Keep real-time protection enabled
• Make sure to update virus definitions frequently
• Consider using an additional firewall if you access public networks.

5. Task Manager and Startup Programs

• Press Ctrl + Shift + Esc
• Check the processes that consume the most CPU or RAM
• Disable unnecessary programs at startup to improve boot performance
• Monitor GPU usage if you use high-performance applications.

6. System temperature analysis

Temperature is a key factor in your PC's health. Use programs like:

• HWMonitor
• Core Temp
• Speccy

These will tell you if your CPU or GPU is overheating, which could be a sign of a poor cooling system or accumulated dust. Excessive temperatures reduce the lifespan of your components.

7. RAM Check

Use the Windows Memory Diagnostic Tool:

• Type "Windows Memory Diagnostic" in the start menu
• Select "Restart now and check for problems"
• The system will reboot and perform a full test of your RAM.

This tool is useful for troubleshooting random crashes, unexpected reboots, or freezes for no apparent reason.

8. Disk status with third-party tools

Tools like CrystalDiskInfo allow you to check the SMART status of your disk:

• Disk temperature
• Time on
• Reassigned sectors
• read/write speed

You can also monitor SSD and HDD drives, anticipating potential catastrophic failures.

9. Power and Battery Check (for Laptops)

• Usa powercfg /batteryreport on the console
• Generates a detailed battery status report
• Check charge cycles, maximum capacity and designed capacity

This diagnostic helps identify batteries that need to be replaced.

10. Using all-in-one third-party tools

Applications like:

• Iolo System Mechanic
• Advanced SystemCare
• Glary Utilities

These tools offer multiple cleaning, optimization, error detection, and scheduled automatic checkups.

Tips to keep your PC healthy

• Update Windows: Install all security and quality updates
• Update drivers: Use tools like Driver Booster or Device Manager
• physical cleaning: Removes dust from fans and components
• Eliminate digital junk: Use Space Cleanup or applications like CCleaner
• Check your software: Remove programs you no longer use
