Finding that your computer can’t keep up while you’re trying to get things done is always an annoying problem. You might have had your computer for a while and it has deteriorated over time. It just doesn’t seem to be working as well as before.

Computers do start to show signs of wear over time, even though they can last quite a long time. Its performance apparently does not last as long though, and this is something that we set out to fix. Slow performance is a very common and inescapable issue for both Windows and Apple computer users who have owned their computer for quite a while. It can be caused by a range of things.

We’ve put together a few upgrade options that you can consider, along with why certain components cause the computer to slow down. This way you can get back to a smooth computing experience that keeps up with your speed.

Things that slow down a computer and how you can fix them

Too many startup programs

Having too many apps that launch at startup can slow down your computer. Some apps have a higher level of impact on the startup process and may take longer for the processor and boot drive to work things out. Programs like antivirus or music apps like Spotify are examples of this.

You can check what startup programs you have from the “Startup” tab from Task Manager. It should also show you the program’s level of impact on the startup process. You may also disable programs that you don’t need launched at startup.

Other than startup programs, long term use and accumulation of installed programs can slow down your OS. You may try refreshing your computer by resetting and reinstalling Windows to free up this space and memory. Or, you can also look up and uninstall unused programs from Control Panel > Programs > Uninstall a program.

Too many apps running in the background

Some apps run in the background while you’re doing something else. Running multiple programs at the same time can take up RAM space and CPU processing workload. If this workload is too exhausting to handle, the computer may run slower than usual. This is also something you can check from Task Manager, under “Apps” and “Background processes”. That way you’ll be able to free up your computer’s workload by stopping some apps that you don’t use.

Virus infection

Getting a virus can get you a lot of trouble. Besides the malicious things like stealing data and corrupting files, viruses also run as a background process. And as we already know, background processes take up RAM space and adds to your computer’s workload whether it likes it or now. And this is a background process that you might not be able to find on Task Manager.

Still, there are obvious signs when you do have a computer virus. These include: random inappropriate pop-up ads, changes to Chrome homepages, or random webpage redirects that you have no control over. Having antivirus software and being careful on the web can help you avoid getting your computer infected with a virus.

Faulty hardware

After you’ve owned your laptop or desktop computer for a while, certain components will show signs of failure. This can be caused by physical damage or natural wear and tear. Even if the device can last long, it’s performance will eventually deteriorate. Hardware failures in components like the hard drive or processor can cause the computer to slow down.

Most of the time, a slow computer is caused by a hard drive failure. The OS boots and operates out of the hard drive, and a damaged hard drive can cause slow read and write times. An accumulation of bad sectors makes things harder for the hard drive to work properly as usual.

Hardware upgrades to speed up your computer

There are a few hardware upgrades you can do to speed up your computer. They each come with their own benefits that apply to different kinds of computing uses and experiences. With this, consider each upgrade with reference to what you want to find the right upgrade for you.

1. CPU

Intel i5 processor core CPU in desktop computer

The CPU (Central Processing Unit) is known as the brain of the entire computer. It is where instructions and calculations are made and executed. The CPU makes decisions and tells the other components what to do with electronic signals sent out via the motherboard.

The processor’s speed is represented with its IPS, that is instructions per speed. IPS is calculated by putting the processor’s clock rate (in hertz) and its IPC (instructions per clock). You can find out your CPU’s performance by running benchmark tests. One thing that affects the performance of the CPU is the number processor cores it uses. These days, consumer-grade CPUs usually come in dual-core or quad-core processors. The more processor cores it makes use of, the more workload the CPU can handle.

There are also different types of CPU you can choose from. This includes Intel Celeron, Pentium, i3, i5, i7, and so on. Upgrading from Intel Celeron or Pentium to an i5 or i7 processor could get you a significant boost. If you’re only looking to upgrade from i5 to i7, there wouldn’t be much of a difference in performance.

If you are looking to upgrade your CPU, be sure to note that you can only do so with a Windows desktop computer. Laptops have their CPU built onto the motherboard, so it’s impossible to just take the CPU out. Getting a CPU upgrade that is compatible with your desktop computer is also important. While a CPU upgrade might seem like an easy choice to speed up your computer, options are quite limited and expensive as well.

2. GPU / Video card

GPU (graphics processing unit) upgrades can greatly benefits users who are keen on gaming or graphics editing. The GPU works to create images on a display, and more so to manipulate computer graphics and image processing.

So if you use your computer largely for gaming or graphics editing, you may want to look into getting a more powerful video card to support your computing needs. Playing games on a weaker graphics card can slow down the display and possibly disrupt your gaming experience.

Like the CPU, laptop video cards are usually embedded on the motherboard. So you can only upgrade your video card if you have a Windows desktop computer. Video cards that are more powerful will draw more power, so you might have to upgrade your power supply to support it.

3. RAM

RAM memory chips

Computer memory RAM is important for multitasking. RAM makes use of volatile memory chips for almost instant access of data that you might need while working on something. This helps to keep things at the ready, rather than your system having to read from the hard drive all the time. So while you have different apps and windows open, the data you may need is readily stored in your computer’s memory.

As RAM comes in set capacities, you may find that need more memory for larger multitasking capabilities. Here are some common RAM capacities, together with its intended use.

  • 4GB — bare minimum for daily personal use
  • 8GB — recommended amount for personal use
  • 16GB — for high graphics use, photo editing software
  • 32GB and more — for movie editing and more

If you do a lot of multitasking, getting a RAM upgrade can get you a 30% performance boost. Before you do, you may also want to check whether your RAM comes in separate chips or is built onto the motherboard. You may add more chips in if they are separate from the motherboard.

4. Hard drive replacement

Hard drives are notorious for being a common computer issue. They don’t last very long and will fail over time. Its performance goes down and may even stop working.

Traditional hard drives contain spinning parts to read and write data. This delicate machinery can be prone to physical damage and bad sectors that causes hard drive failure. While bad sectors do sound a bit intimidating, its something that all hard drives have. Nothing’s perfect, and so is the case for the hard drive manufacturing process. Even brand new hard drives come with a tiny amount of bad sectors, and they will accumulate over time.

When bad sectors on a drive accumulates to an intolerable point, the drive will start to fail. This will become noticeable if you start noticing slow boot up times or long response times from apps. You can refresh your system by getting a new drive, preferably a better performing one if you want. A hard drive replacement is one of the most effective and quickest way to refresh and speed up your computer, you can even do it yourself easily!

5. Switching to a solid-state drive (SSD)

For the best of both worlds, consider an SSD upgrade. SSDs are better for both durability and performance, offering things that a traditional HDD can’t. It makes use of non-volatile NAND memory, which does not require moving parts to operate. This lowers the risk of accidental physical damage, which makes it longer-lasting than HDDs.

Switching to an SSD from an HDD is a very popular upgrade solution these days as a quick performance boost. It can offer speeds up to 16 times faster than an HDD, which is a huge boost for performance. Along with hard drive replacements, SSD upgrades can be a quick and worthwhile solution to slow laptops or desktop computers. However, if you’re thinking about getting an SSD upgrade together with a RAM upgrade, it might not be necessary. SSDs are already fast enough for multitasking and other uses that RAM assists with, so you might not even need that much more RAM along with the SSD.

Checking your computer for possible problems

Running diagnostics on your computer from time to time can be helpful even if your computer is running fine. You might also be able to find out why your laptop or desktop computer is running slower than usual, if it turns out to be a hardware issue. Simple apps like chkdsk can help you detect and repair bad sectors, while full diagnostics tests or dedicated hardware analysis software can help you do more than simple tests.

Running diagnostics on your laptop or desktop computer

Your computer should come with built-in apps specific to its brand that you can use to run full diagnostics on hardware. These are apps like Dell SupportAssist or HP Support Assistant. This offers specific tests and solutions tailored to your model of computer.

Otherwise, you may also choose to run diagnostics from startup, also known as boot diagnostics, or pre-boot diagnostics. You can enter boot diagnostics by entering a key specific to your computer’s brand. For Dell it’s For Dell it’s “F12”, “ESC” key for HP, “Enter” key for Lenovo laptops, and “D” key for Apple Macs. Your system will report possible hardware issues found on components such as the fan, processor, or hard drive. Your slow computer problem could be traced back to hardware issues, or simply some other software problems.

Getting professional upgrades and repairs

Finding yourself not so technologically adept? Don’t have the time to do more research? Getting professional help from a technician might be what you’re thinking about doing. You can get help from an authorised service centre or a third-party service. Or, simply getting advice from an experienced retailer can also be beneficial.

For authorised service centres, they can usually offer free computer servicing if your device is still covered by warranty or care. While an authorised service centre can get you specialised services, they might not be able to fix your device if it is too old or offer upgrade services.

Some might choose to go to a third-party repair service instead, if their warranty has run out, or they might not live close enough to a service centre.
