How Long Do Computers Last and When to Replace Them


Technology is rapidly advancing and changing. But, unfortunately, this also means our computers and devices have shorter lifespans. So then, how long do computers last? What factors determine how long they operate, and how can we extend their lives? This article addresses these questions and more.

When Is a Computer Outdated?

The average computer lifespan is three to four years. When technology development wasn’t so prevalent, the average life of a computer was about five years. So if more than five years have passed since you’ve bought a new computer, perhaps it’s time to purchase a more up-to-date device.

Is my computer outdated? A few telltale signs—typically with your CPU, GPU, and RAM—may indicate that your computer is obsolete and needs to be replaced. For example, if your computer takes longer to boot up or experiences more system crashes, it might be time for a new one. Additionally, if you’ve noticed that other hardware isn’t performing as it should, then it’s probably time for an upgrade.

DID YOU KNOW? If the graphics on your screen are distorted or pixelated, you have an outdated computer—it might be time to replace it.

How Long Do Computers Last?

Computers and laptops are essential parts of our lives. We use them for school, work, entertainment, and more. And we want a computer that will last a lifetime. But how long should computers last in reality? While neither laptops nor computers have a shelf life—like products in a supermarket—they become slower over time. The average lifespan of a computer could potentially be five to eight years if maintained properly. Old desktop computers can last for a long time if you constantly upgrade or replace defective components.

DID YOU KNOW? If you plan on using a device from the comfort of your home, a desktop PC would be a better, cost-efficient choice with a longer lifespan.

Laptop vs Desktop Lifespans

As a rule of thumb, PCs last longer than laptops. But how long do laptops last? Laptops are designed to be portable and much smaller and lighter than PCs. As a result, they can be susceptible to overheating, which can damage their hardware and shorten the lifespan of the device. The average life of a laptop is between three to five years.

A desktop computer, however, typically has better ventilation and air circulation than a laptop, which helps keep it cooler and prevents any component from overheating.

DID YOU KNOW? A laptop is more prone to getting damaged and more difficult to upgrade than a desktop.

Signs You Need a New Computer

If you’re nearing the average lifespan of your PC, consider the following signs that you need a new one.

  • Slow Performance

A lack of free space on your hard drive, not enough memory (RAM), or a slow processor can affect your device.

  • Overheating

A computer often overheats when there is a lot of dust, which can clog up fans and ventilation systems.

  • Blue Screen 

If you encounter frequent blue screens—typically caused by a hardware problem or faulty operating system—it could be an indication that your computer needs to be replaced.

DID YOU KNOW? There are various things you can do with an old computer. If you’re purchasing a new device, consider donating your old one to a charity or simply give it to someone who needs a computer.

Key Takeaways

The average life of a laptop is three to five years.
PCs last much longer than laptops.
Laptops have a smaller internal space for cooling.
If your computer overheats, it’s generally time for a new one.

Extending Computer Life

Even though the life expectancy of computers is three to five years, you can find ways to extend its life. There are several components you can upgrade or replace to improve the performance of your PC. The biggest culprit in slowing down a computer is its RAM. Upgrading the RAM (memory) will help your computer to run faster. Additionally, replacing the hard drive with a solid-state drive (SSD) will also help speed up your machine.

If it takes forever to open a folder on your monitor, it can indicate that your processor is outdated. A new processor will help improve the performance of your computer by reducing lag time and improving boot times.

DID YOU KNOW? One way to extend your computer lifespan is by finding ways to speed up your computer.

Buying a New Computer

When purchasing a new computer, there are several essential factors to consider to get the most out of your investment. First, make sure you choose a suitable model for your needs and consider how often (and for what) you’ll be using it. Remember that the average life of a desktop computer is three to five years. So there’s no need to buy the most expensive one because you’ll need to replace it in less than 10 years.

Before you decide to buy a computer, find the one you like within your price range and be sure to read reviews about it to get an idea of what others think. Additionally, check for available discounts and deals.

When buying a computer, consider the following essential components.

  • Processor: The processor’s speed determines how well your computer can handle multitasking or complex projects.
  • Graphics Card: A robust graphics card is essential if you plan on gaming or using your computer for graphic-intensive tasks.
  • RAM: The more RAM your computer has, the faster it will run.
  • Operating System: Make sure the operating system is compatible with the software and hardware you plan to use.
  • Battery Life: Consider how long the battery will last before recharging.
  • Hard Drive: The size of your hard drive determines how much data you can store.
DID YOU KNOW? How long can computers last depends largely on two components. Namely, the most commonly changed components of computers are the motherboard and processor.


The lifespan of a computer depends on the type of tasks it’s used for and how well it has been taken care of. But no matter how well you maintain your computer, there will come a time when it needs to be replaced. This guide has aimed to help you understand how long computers last and how to extend the life expectancy of your computers or when to purchase a new one.


How often should you replace your computer?

A good rule of thumb is to replace your computer every three to four years. This estimate is based on cost analysis and the time it takes for the internal parts to malfunction.

Can a laptop last 20 years?

No. A laptop will not last 20 years because, primarily, it will not support sufficient upgrades and, therefore, become outdated.

Can a computer last 10 years?

How long do computers last? They could last 10 years if properly maintained and not used excessively. Keep your machine well-ventilated in a cool, dry place, and try to avoid direct sunlight.
