SLOWLow

Computer Running Slowly

What this error means

A slow computer is one of the most common complaints. Your system might take forever to boot, applications may lag, or everything just feels sluggish. This isn't a specific error, but rather a symptom of various underlying issues.

The good news is that in most cases, you can significantly improve performance without buying new hardware.

Common causes

  • 1Too many programs running at startup
  • 2Insufficient RAM for your workload
  • 3Nearly full storage drive
  • 4Malware or unwanted software
  • 5Outdated operating system or drivers
  • 6Hardware showing its age
  • 7Overheating causing thermal throttling

How to fix it

Step 1: Restart Your Computer

It sounds simple, but a restart clears temporary files and resets processes. Many people rarely fully restart their computers.

Step 2: Check What's Using Resources

  • Windows: Open Task Manager (Ctrl + Shift + Esc), click "More details", and check CPU and Memory usage
  • Mac: Open Activity Monitor (Applications → Utilities) and check CPU and Memory tabs

Step 3: Reduce Startup Programs

  • Windows: Task Manager → Startup tab → Disable unneeded items
  • Mac: System Settings → General → Login Items → Remove unneeded items

Step 4: Free Up Storage Space

Keep at least 10-15% of your drive free. Delete unused files, empty trash, and uninstall programs you don't use.

Step 5: Run a Malware Scan

Use Windows Defender (built-in) or a reputable antivirus to check for malware that might be slowing your system.

Step 6: Update Everything

Install the latest OS updates and driver updates. These often include performance improvements and bug fixes.

Step 7: Consider Hardware Upgrades

If software solutions don't help:

  • Add RAM: 8GB minimum, 16GB recommended for most users
  • Upgrade to SSD: The single biggest performance boost for older computers

When to seek help

A slow computer is usually fixable, but consider professional help if:

  • The slowdown happened suddenly without any changes
  • Your computer is less than 2-3 years old and struggling
  • You hear unusual clicking or grinding sounds
  • The slowness persists even after a clean OS reinstall

These could indicate hardware problems that need diagnosis.
