What to Do When Your Computer Is Running Slow

Quick Fixes to Try First

Before calling IT, try these simple steps:

1. Restart Your Computer

Many slowness issues are fixed by a simple restart:

• Save your work
• Click Start > Power > Restart
• Wait for it to fully restart

2. Close Unused Programs

Each open program uses resources:

• Close browser tabs you don't need
• Close applications you're not using
• Check for programs in the system tray

3. Check What's Using Resources

Windows:

• Press Ctrl + Shift + Escape to open Task Manager
• Click More details if needed
• Look at the CPU and Memory columns
• Close programs using high amounts

Mac:

• Open Activity Monitor (search in Spotlight)
• Check CPU and Memory tabs
• Close resource-heavy apps

Common Causes of Slowness

Too Many Browser Tabs

Each tab uses memory. Close tabs you don't need:

• Right-click the tab bar
• Click Close other tabs

Too Many Startup Programs

Programs that start with Windows slow down boot time:

• Press Ctrl + Shift + Escape
• Click the Startup tab
• Disable programs you don't need at startup

Low Disk Space

When your drive is almost full:

• Delete files you don't need
• Empty the Recycle Bin
• Move files to OneDrive

Software Updates Needed

Outdated software can run slowly:

• Check Windows Update
• Let updates install
• Restart after updates

When to Contact IT

Contact IT if:

• Slowness persists after trying these steps
• Your computer freezes frequently
• You see error messages
• One specific program is always slow
• Your computer has been slow for days

What IT Might Do

We may:

• Run diagnostic tools
• Check for viruses
• Add more memory
• Replace old hardware
• Optimise system settings

Preventing Future Slowness

Good habits:

• Restart regularly (at least weekly)
• Close programs when done
• Keep software updated
• Don't install unnecessary software
• Save files to OneDrive, not your hard drive
