Why Is My Computer Running So Slow and How Can I Fix It?

Dear PCtronics,
Long-time tech struggler, first-time writer here. I swear my computer used to be fast, but lately, it’s been dragging. The slow computer performance is killing my productivity. Programs take forever to open, my browser tabs crash like a toddler who skipped naptime, and even my cat judges me when I click something and stare at the screen, waiting.

What’s going on? Am I cursed? Is my PC just as tired as I am? Or (I’m afraid to even type it out) do I need to buy a new one? Please tell me there’s hope.

Sincerely,
Lagging Liam


Dear Lagging Liam,
First off, you’re not cursed… unless you’ve been clicking on some pretty suspicious, hieroglyphic-based websites – but let’s assume you’re just dealing with slow computer performance and not ancient tech magic. The good news? There’s plenty you can do before you even have to think about replacing your computer.

Here’s your IT survival guide to speeding things up:

Have You Tried Turning It Off and On Again? (Yes, It Actually Works)

It’s the oldest trick in the book, but it works. Restarting clears temporary files, resets processes, and gives your system a fresh start. If you haven’t shut down in weeks, consider this your sign. Restarting alone can significantly increase your computer’s slow performance and have you running smoothly again.

Is Something Hogging Your Computer’s Resources?

Press Ctrl + Shift + Esc to open Task Manager (Windows) or Command + Space, then type “Activity Monitor” (Mac). If something’s eating up all your CPU or memory (like maybe that browser with 47 tabs open), it’s time to close a few things down. Multitasking is great, but too many open apps can bring your computer to a crawl.

Could Storage Space Be Slowing Your Computer’s Performance?

A nearly full hard drive slows everything down. Try these quick fixes:

  • Delete unused files and programs
  • Empty your Recycle Bin/Trash
  • Run Disk Cleanup (Windows) or Optimize Storage (Mac)

Storage issues are a common cause of slow computer performance. Freeing up space can make a noticeable difference.

Have You Ignored Those Update Notifications?

Outdated software can cause lag. Make sure your operating system, drivers, and programs are up to date. If Windows Update has been nagging you – listen to it! Updates often include performance enhancements that fix underlying issues.

Could Malware Be Sneaking Around?

Sometimes, it’s not you – it’s a sneaky virus slowing things down. Run a full system scan with a trusted antivirus or the built-in application Windows Defender. Malware can drain resources and significantly affect computer performance. Regular virus scans help keep your system secure and fast.

Does Your Computer Need a Little Upgrade Love?

If your PC is older, adding more RAM or swapping your hard drive for a Solid State Drive (SSD) can be a game-changer. It’s like giving your computer a shot of espresso. More RAM allows your computer to handle multiple tasks simultaneously, while an SSD dramatically reduces loading times.

Are Too Many Startup Programs Causing Slow Computer Performance?

Too many programs launching at startup can also slow things down to a crawl. In Task Manager (Windows) or System Preferences > Users & Groups (Mac), disable unnecessary startup apps – things like internet browsers (Chrome, Opera, etc.), game management software (Steam, Origin, etc.), or communication software (Discord, Teams, etc.). Trimming startup programs helps your computer boot faster and run smoother.
