A sluggish computer is one of the most common complaints we hear from customers across Baltimore, Howard, Harford, and Carroll Counties. The good news? In most cases, you don't need a new machine — you just need a little maintenance.

Before you spend money on a replacement, try these seven simple fixes. Most take only a few minutes, and you don't need to be a tech expert to do them.

It sounds almost too simple, but restarting your computer can solve a surprising number of problems. When your computer runs for days or weeks without a restart, programs and background tasks can pile up and slow everything down.

Save your work, close your programs, and choose Restart from the Start menu or Apple menu. Don't just close the lid — that puts the computer to sleep, which is different from a full restart.

Every open program uses some of your computer's memory. If you have a dozen browser tabs open, plus email, music, photos, and a few other programs running, your computer has a lot to manage.

Close anything you aren't actively using. In your web browser, keep only the tabs you need right now. You can always bookmark a page and come back to it later.

Computers need free space to work smoothly. When your hard drive is almost full, your computer can slow down dramatically.

On Windows: Open File Explorer, click This PC, and look at the bar under your main drive. If it is mostly red, you need to free up space.

On a Mac: Click the Apple menu → About This Mac → Storage.

Start by deleting files you no longer need, emptying the Recycle Bin or Trash, and moving large photos or videos to an external drive or cloud storage.

Many computers collect programs over time — free trials, old games, printer software, and apps you installed once and forgot about. Some of these programs start automatically when you turn on your computer.

On Windows, go to Settings → Apps → Installed Apps. Look through the list and uninstall anything you recognize but no longer use. If you aren't sure what a program does, don't remove it yet. Take a picture of the name or ask for help first.

Updates can feel like an interruption, but they often include performance improvements and important security fixes.

On Windows, go to Settings → Windows Update and choose Check for updates. On a Mac, open System Settings → General → Software Update.

Let updates finish completely before turning your computer off. If your computer asks to restart, do it when you have a few minutes to spare.

Viruses, unwanted browser extensions, and other malicious software can make a computer slow or behave strangely.

Windows includes built-in security protection. Search for Windows Security, open it, and run a quick scan. On a Mac, be cautious about unfamiliar downloads and browser extensions. If you see repeated pop-ups, strange ads, or programs you don't remember installing, it is a good idea to get help.

Never call a phone number from a pop-up warning. Legitimate security companies do not demand payment through a surprise browser message.

If your computer is still slow after these steps, the issue could be an aging hard drive, too little memory, overheating, or a program that needs a closer look. That does not automatically mean you need a new computer.

A technician can often tune up the system, remove unwanted software, upgrade a component, or help you decide whether repair makes sense. At My Neighbor Tech, we explain the options clearly so you can make a confident decision.

Restarting, clearing space, installing updates, and closing unused programs can make a real difference. Try one or two fixes at a time, then see how your computer feels.

If you would rather have someone handle the troubleshooting with you, My Neighbor Tech provides patient, in-home technology support throughout Maryland.
