How to Run Diagnostics on Your Computer

Running into computer issues can feel frustrating. Sometimes the screen freezes, programs slow down, or things just don’t work right. That’s when it helps to run PC diagnostics and check computer health. These steps help you find and fix problems before they get worse.

What Does It Mean to Run PC Diagnostics?

When you run PC diagnostics, you use tools that scan your computer’s parts to see if they’re working right. This includes the hard drive, memory (RAM), battery, and more. Running these tests helps you check computer health and find any hidden issues.

Why It’s Important to Check Computer Health

Your computer is like your body—it needs regular checkups. When you check computer health, you make sure your system stays strong and works well. It can even make your computer last longer. Ignoring problems only makes things worse over time.

Signs That You Should Run PC Diagnostics

• Your computer is slow
• Programs keep crashing
• It takes too long to turn on or shut down
• You see error messages often
• The fan is too loud or the laptop gets hot

If you notice any of these signs, it's a smart move to run PC diagnostics and check computer health.

1. Windows Built-in Tool

If you use Windows, follow these steps:

1. Press the Windows key.
2. Type "Windows Memory Diagnostic."
3. Click and choose “Restart now and check for problems.”

These habits will help you check computer health often and avoid big problems later.

What to Do After the Scan

• Backup your files just in case

Don’t ignore the results. Fixing small issues early can prevent full crashes.
