What you will need: Your computer, about 15 minutes, and a pen and paper (or a notes app) to write down what you find.

Computers don't stop working on a set birthday. They slow down, get harder to keep secure, and eventually cost more in frustration than they're worth. This guide walks you through the warning signs and a few quick checks, then helps you decide whether to repair, upgrade, or replace.

If your computer is already failing (crashing often, making strange noises, or refusing to start), skip to Step 6 and back up your files first.

Step 1: Look for the everyday warning signs

You probably already know if some of these apply. Note any that sound familiar:

  • It takes several minutes to start up, or to open programs you use every day.
  • It freezes or "hangs" (stops responding) several times a week.
  • It crashes or restarts on its own.
  • The fan is loud all the time, or the computer gets very hot.
  • The battery (on a laptop) runs down quickly, or the laptop only works plugged in.
  • Programs you need won't install or run anymore.
  • Your printer, scanner, or other equipment no longer works with it.

One or two of these may just mean it needs a cleanup. Several at once, especially if they're getting worse, point toward replacement.

Step 2: Find out what you have and how old it is

There's no official expiration date for a computer, but knowing its age and specs helps you make sense of the other checks.

On Windows:

  1. Click Start, then Settings (the gear icon).
  2. Go to System, then About.
  3. Under Device specifications and Windows specifications, write down the processor (the computer's "brain"), the installed RAM (short-term memory that helps it juggle several tasks), and the Windows edition and version.

On a Mac:

  1. Click the Apple menu in the top-left corner.
  2. Click About This Mac.
  3. Write down the model name and year, the chip or processor, and the memory.

Can't tell how old it is? Search online for the model name or number you wrote down. The manufacturer's website, or your original receipt or invoice, will usually show the release or purchase date.

Step 3: Check your storage

Storage is where your files, your programs, and the operating system (Windows or macOS) live. When it's nearly full, a computer can slow down noticeably.

On Windows:

  1. Open Settings, then System, then Storage.
  2. Note how much space is used and how much is free.

On a Mac:

  1. Click the Apple menu, then System Settings.
  2. Go to General, then Storage. (On older versions of macOS, choose About This Mac, then the Storage tab.)

Check what kind of drive you have. Older computers often have a hard disk drive (HDD), which has spinning parts and is slower. Newer ones have a solid-state drive (SSD), which has no moving parts and is much faster. To check on Windows:

  1. Click Start and type defrag.
  2. Open Defragment and Optimize Drives.
  3. Look at the Media type column. It says Solid state drive or Hard disk drive.

What it means: If your storage is nearly full, delete files you don't need or move old ones to an external drive. If that fixes the slowness, you may not need a new computer. If you have a hard disk drive, swapping it for an SSD is often worth asking about (see Step 5).

Step 4: Check that it still gets security updates

This is the most important check. Software makers eventually stop releasing security updates for older systems. The computer still runs after that, but it's more exposed to viruses and other threats.

On Windows:

  1. Open Settings, then Windows Update (on Windows 10, it's under Update & Security).
  2. Click Check for updates.
  3. Note whether updates install normally or it reports a problem.

If your computer runs Windows 10: Microsoft ended regular support for Windows 10 on October 14, 2025. Some computers can still get security fixes for a limited time through Microsoft's Extended Security Updates program, but that's a short-term bridge, not a plan. Check whether the computer can move to Windows 11 using Microsoft's free PC Health Check app, downloaded from Microsoft's Windows 11 page. If it says the PC can't run Windows 11, that's a strong sign to plan a replacement. Our guide to Windows 10 end of support covers your options in detail.

On a Mac:

  1. Click the Apple menu, then System Settings.
  2. Go to General, then Software Update.
  3. If your Mac says it can't update to the latest version of macOS, write down which version it's on.

Apple doesn't publish a fixed end date for each version of macOS, and older versions don't always get every security fix. Apple's security releases page (linked in Sources) lists which versions received recent updates, so check that yours is still on it.

What it means: A computer that no longer gets security updates is a business risk, especially if you handle customer information, payments, or banking on it.

Step 5: Decide whether to repair, upgrade, or replace

Use your notes from the steps above and ask yourself:

  • Is it one specific problem? A worn-out battery, a cracked screen, or a full drive is often worth repairing.
  • Can it still get security updates? If not, a repair only delays the problem. Replacing it is usually the better choice.
  • Would an upgrade fix the slowness? On some computers, adding memory or swapping a hard disk drive for an SSD makes a big difference. Many newer laptops can't be upgraded this way, so check your model first.
  • How does the repair quote compare to a replacement? If the repair would cost a large share of what a new computer would, that money is usually better spent on the new one.
  • Is it holding your business back? If it slows you down every day, that lost time adds up.

A simple rule of thumb:

Situation Lean toward
One failed part, and the computer otherwise runs well and gets updates Repair
Slow, but storage or memory is the cause and the model can be upgraded Upgrade
No longer gets security updates Replace
Several problems at once, and it's several years old Replace

Step 6: Protect your files before anything else

Whether you repair, upgrade, or replace, back up first.

  1. Copy your important files (documents, photos, accounting data, customer records) to an external drive or a cloud storage service.
  2. Make a list of the programs you use and where your license keys or logins are kept.
  3. Make sure you can sign in to your email, banking, and software accounts from another device. A password manager is the safest place to keep those passwords; avoid sticky notes or a plain document on the computer.
  4. If the computer is failing, back up right away, before you do anything else.
