Over time, PCs collect “digital lint.” The most common culprits are?

Dealing with Windows issues can feel like trying to solve a puzzle where the pieces keep changing shape. Whether your PC is acting sluggish or giving you the “Blue Screen of Death,” here is a quick guide to the most common troubleshooting questions.

🚀 Performance & Speed

Why is my computer running so slow?

Over time, PCs collect “digital lint.” The most common culprits are:

• Too many startup apps: Programs that launch the moment you log in.
• Low Disk Space: Windows needs “breathing room” (usually about 10-15% of your drive) to swap files.
• Background Processes: Use Ctrl + Shift + Esc to open the Task Manager and see what’s eating your CPU or Memory.

How do I fix a “Frozen” application?

If an app stops responding, don’t just keep clicking—that usually makes it worse.

1. Press Alt + F4 to try and force close the active window.
2. If that fails, use Task Manager, right-click the app, and select End Task.

🛠️ System Errors & Updates

What should I do about the Blue Screen of Death (BSOD)?

Contrary to its dramatic name, it’s usually just Windows protecting itself from a hardware or driver conflict.

• The Fix: Take note of the Stop Code (e.g., CRITICAL_PROCESS_DIED). Restart your computer first; often, Windows will self-correct. If it persists, boot into Safe Mode and roll back recent driver updates.

Windows Update keeps failing. Help?

Updates can get stuck in a loop.

• Solution: Go to Settings > System > Troubleshoot > Other troubleshooters and run the Windows Update troubleshooter. It’s surprisingly effective at clearing out “stuck” update files.

🌐 Connectivity & Hardware

Why won’t my Wi-Fi connect?

Before you call your ISP, try the “Network Reset”:

1. Go to Settings > Network & internet > Advanced network settings.
2. Select Network reset.

Note: This will wipe your saved Wi-Fi passwords, so make sure you have them handy!

My printer is “Offline” but it’s plugged in.

Windows and printers have a historically rocky relationship.

• Clear the Print Spooler: Open the Services app, find “Print Spooler,” right-click it, and select Restart. This often “pokes” the printer back into communication.

Switching gears to macOS! While Macs have a reputation for “just working,” they certainly have their own unique set of quirks—from the “Spinning Beachball of Death” to apps that refuse to quit.

Here are the most common troubleshooting questions for Mac users.

🏎️ Performance & System Health

Why is my Mac so slow (and the fan so loud)?

High fan noise usually means your processor is working overtime, generating heat.

• The Culprit: Often a “runaway process.” Open Activity Monitor (Cmd + Space, then type “Activity Monitor”). Look at the % CPU column. If an app is using 90%+, highlight it and click the X at the top to stop it.
• Storage: macOS needs at least 10–15GB of free space to handle “swap files” (temporary memory). If your disk is full, the system will crawl.

How do I fix the “Spinning Beachball”?

This means the application is hung or waiting for a resource that isn’t responding.

• The Fix: Use Force Quit. Press Option + Command + Esc, select the frozen app, and hit Force Quit. It’s the Mac equivalent of “End Task” on Windows.

🔌 Hardware & Startup Issues

What is “Safe Mode” and how do I get there?

Safe Mode clears caches and prevents unnecessary “startup items” from loading.

• Apple Silicon (M1/M2/M3): Shut down. Press and hold the Power button until you see “Loading startup options.” Select your disk, hold Shift, and click Continue in Safe Mode.
• Intel Macs: Restart and immediately hold the Shift key until the login window appears.

My Mac won’t charge or the USB ports aren’t working.

On older Intel Macs, you might need to reset the SMC (System Management Controller). On newer Apple Silicon Macs, a simple restart usually handles this as the “reset” happens automatically during boot.

---

📂 Software & Permissions

An app says it “cannot be opened because it is from an unidentified developer.”

Apple’s “Gatekeeper” security is blocking the app.

• The Fix: Don’t just click “OK.” Go to System Settings > Privacy & Security. Scroll down to the “Security” section, and you should see a button that says “Open Anyway.”

“The disk was not ejected properly.”

If you see this notification constantly even when the drive is plugged in, your Mac might be “sleeping” the USB ports too aggressively.

• Tip: Check your Battery/Energy Saver settings and disable “Put hard disks to sleep when possible” if you use external drives for backups.

🛠️ Essential Mac Maintenance

Action	Shortcut / Tool
Spotlight Search	Command + Space (Finds anything instantly)
Screenshot (Selected Area)	Shift + Command + 4
Reset NVRAM/PRAM	Opt + Cmd + P + R (Intel only; fixes sound/display bugs)
Disk Utility	Use First Aid to repair directory permissions.

🛠️ Scenario A: Stuck on a Specific Screen

If your Mac isn’t reaching the desktop, the icon on the screen tells us exactly what’s wrong:

• Folder with a Question Mark: Your Mac can’t find its operating system.

• The Fix: Shut down, then hold Command + R (Intel) or the Power Button (Apple Silicon) to enter Recovery Mode and use Disk Utility to “First Aid” your startup disk.

• Prohibitory Symbol (Circle with a line): Your Mac found an OS, but it’s not compatible with your hardware. This often happens after a failed update.

• Blank Black or Gray Screen: This is usually a power or display issue. Try a “Hard Restart” by holding the power button for 10 full seconds.

🧹 Scenario B: Doing some “Spring Cleaning”

If you’re just trying to speed things up, here are the three most effective things you can do right now:

1. Clear the “Login Items”

Programs often sneak into your startup routine, slowing you down.

• Go to System Settings > General > Login Items.
• Remove anything you don’t need launching immediately under “Open at Login.”
• Toggle off unnecessary background apps under “Allow in the Background.”

2. Run Disk Utility First Aid

This is the Mac equivalent of “tuning the engine.”

1. Open Disk Utility (found in Applications > Utilities).
2. Select Macintosh HD in the sidebar.
3. Click First Aid at the top and let it run. It will freeze your Mac for a minute—that’s normal!

3. Clear System Caches

If an app is acting “weird” (crashing or glitchy), its cache might be corrupted.

• In Finder, press Shift + Command + G.
• Type ~/Library/Caches and press Enter.
• You can safely delete the folders of apps you no longer use or are currently troubleshooting.
