Common Terms


RAM means Random Access Memory, and is what your computer uses to store things that it is thinking about while it is on. When your computer turns off, everything in RAM goes away.

Memory Corruption

Memory corruption occurs when a part of your RAM is changed due to an error. Parts of your computer's memory get confused and display the wrong data

RAM upgrade RAM (short for Random Access Memory) is a kind of temporary data your computer needs in order to run. It’s stored on RAM chips, which are plugged into your computer’s motherboard. A lot of our customers get a bit confused about RAM, so in this article, we’ll give you a quick and simple overview of what it is, how it works and how you can tell if something is not quite right with your RAM.   If your computer is crashing all the time, running very slowly or if you’re getting blue-screen errors, get in touch with your friendly neighborhood nerds! We’ll diagnose the problem and can repair or replace your RAM for you. You can call us at 1-800-919-6373 or fill out our contact form. We’re here to help.

Storage versus Memory

To understand what RAM does, it’s important to understand the difference between storage and memory. So let’s begin there.   Computers deal with data. No surprises there! However, there are two broad data-related processes your computer does all the time and these are very different from one another. One is storage. The other is memory. It’s easiest to describe the difference by drawing some parallels with how we humans tend to think.


You can know something without actively thinking about it. For example, you can know that Washington DC is the capital of the United States without actively thinking about it every moment. Its tucked away on a squishy neuron hidden in your brain somewhere, waiting to be recalled when you actually need that information. It’s a bit like a mental sticky note. Sticky notes This is exactly how data storage on your hard drive works. Even though your computer isn’t actively doing anything with that data, it’s still there waiting to be accessed. Just like our knowledge, it’s persistent. In other words, just because you stop thinking about that knowledge doesn’t mean it’s going away.  

The key point to remember: persistent data storage happens on your computer’s hard drive.


There’s also the information you’re thinking about and actively using in any given moment. For example, if you’re driving your car to work, your brain will be feeding you all the information you need to drive your car at that moment so that you can get to your destination safely without crashing.   This is exactly how RAM works in your computer. Your computer stores everything it is currently thinking about in RAM. If you’re running a program, it is in RAM. If you’re looking at a web page, you guessed it, it’s in RAM. The more RAM you have, the more your computer is able to think about at the same time. Juggling

The key point to remember: temporary processing of memory happens on your computer’s RAM.

Now for the confusing part!

People frequently get memory and storage mixed up which means they also get hard drives and RAM chips confused too. A big reason for this is that they both deal with data and no matter what it’s used for, data is always measured with the same unit: the byte (note that kilobytes, megabytes, gigabytes are all just ways of referring to hundreds, thousands and millions of bytes).   People often assume (understandably) that because RAM and hard drive capacity are both measured in gigabytes, they must be the same thing. They absolutely are not.  

The key point to remember: while their data-capacity size is measured using the same unit, hard drives and RAM chips are not the same. They’re different components and they perform different functions.

What happens if your RAM isn’t working properly?

If your RAM isn’t working properly, you’ll probably notice some pretty significant and obvious problems:  
  • Your computer may frequently crash or restart unexpectedly.
  • Your files may become corrupt, especially those you recently used.
  • Your files may also simply disappear from your hard drive.
  • You may hear three beeps when you start your computer. This can indicate memory problems encountered on startup.
  • Your computer may also simply be running very slowly. If this is happening it could be that your RAM is damaged or it could simply mean that you require more RAM in order to run your software properly.
  If you’re experiencing any of these problems and would just like a second opinion on what to do about it, you can always contact us for advice as you might need a RAM upgrade.

A simple test you can run on Mac and Windows

If you’re confident with a bit of light tinkering, it is possible to run a simple test to check on the health of your RAM.   If you’re on a Mac, shut down and restart your computer. While it is restarting hold down the ‘D’ key on your keyboard. Keep the key down until a diagnostic screen appears. Follow the on-screen prompts to activate your Mac’s self-check sequence. If there are problems, a screen will appear describing the problem and provide reference codes. These codes are useful for reference if you need to speak with a technician, so it’s a good idea to note these down.   On a Windows PC, you can run the Memory Diagnostic Tool. Open the Start menu and type in “Windows Memory Diagnostic”. Your computer will request to reboot. On confirmation, your computer will restart and run its tests. When the tests are complete the computer will once again reboot and a screen will pop up showing you the results. RAM

Questions nerds often hear about Desktop RAM Upgrade & Repair

What does RAM stand for?

Recreational Aardvark Mocking. It also means Random Access Memory which is probably more relevant in this context.


My computer is so slow. Is RAM the issue?

It’s often a big part of the issue. Your CPU is another big factor. We can run a diagnostic on your computer and look at the kinds of software you’re trying to run. We can offer you sensible advice on whether extra RAM would help and provide a free quote.


I’m getting all these file corruption errors. How do I fix it?
