Problem #2: Computer Won’t Turn On

Symptoms: Black screen, no lights, no fan noise

Fix: Check Power & Connections

Laptop:

1. Plug in charger and wait 15 minutes
2. Try a different outlet
3. Check if charging light comes on
4. If no light, charger might be dead (try borrowing one to test)

Desktop:

1. Check if power cable is fully plugged into wall AND computer
2. Flip the power switch on the back of the computer (easy to accidentally hit)
3. Test outlet with another device

Mac-specific:

• Press and hold Power button + Shift key for 10 seconds
• Release, wait 5 seconds, press Power again

Still nothing? Likely hardware issue. Time to call for help or visit a repair shop.

Problem #3: Computer is Really Slow

Symptoms: Takes forever to boot, programs lag, spinning wheel of death

Fix: The Slowness Checklist

Step 1: Restart (solves 30% of slowness issues)

Step 2: Check Disk Space

• Windows: Open File Explorer → This PC → See how full your C: drive is
• Mac: Apple Menu → About This Mac → Storage
• If 90%+ full: Delete old files, empty recycle bin, move photos/videos to external drive

Step 3: Disable Startup Programs

Windows:

1. Press Ctrl + Shift + Esc (opens Task Manager)
2. Click Startup tab
3. Right-click programs you don’t need at startup → Disable
   • Keep: Antivirus, cloud storage (if you use it)
   • Disable: Spotify, Skype, Adobe Creative Cloud, anything you don’t use daily

Mac:

1. System Preferences → Users & Groups → Login Items
2. Select items you don’t need → Click – (minus button)

Step 4: Update Everything

• Windows: Settings → Windows Update → Check for updates
• Mac: System Preferences → Software Update

Step 5: Run Malware Scan

• Windows Defender (built-in on Windows)
• Malwarebytes (free version works great)

Still slow? You might need more RAM, an SSD upgrade, or a deep clean. That’s when you call us.
