The 5 best programs to test the performance of your PC for free

Maybe it has happened to you that you need to quickly enter a video class, or do some urgent work on your computer, but when you turn it on you realize that the system works a little slow or starts to show some errors when running your applications.

It is normal that this situation occurs in all computers, no matter the model, brand or operating system you are using, there always comes a time when something goes wrong. This causes the performance of the computer to decrease and makes the whole system in general prevents us from performing our tasks smoothly.

In many occasions the failures that our computers present can be solved in a simple way. That is why you should have at hand some tools to test your computer and thus, know what may be causing problems in its operation.

Here is a list of the best 5 programs that you can use to test your PC and detect any problems.

1. AIDA 64 Extreme

This is the most complete program if we talk about analyzing and testing all the components of our computer.

One of the features that has made this program so popular is the detailed information it gives us about each of the devices that we have installed on our pc.

AIDA 64 Extreme gives us access to driver updates, detailed information about the product or device and additional features that will be very useful if any of these components fail.

Best of all, this program is totally free.

2. UserBenchmark

This is one of the most popular computer testing tools available today , as its effectiveness in detecting faults is extremely efficient.

It comes equipped with a database that will compare the performance of your computer’s components with the average results of all the people who use the application.

UserBenchmark performs an in-depth analysis of CPU, hard drives, USB drives, RAM memory and graphics card performance.

Among the results of the analysis it performs on the components, it also provides the average price of each one of them so that we can analyze whether it is convenient to repair that component or buy a new one.

3. MemTest 64

MemTest 64 is the perfect tool to perform an exhaustive analysis of your computer’s RAM memory. RAM is directly related to the fluidity of the system and many other problems that cause excessive slowness in the computer.

It is here where MemTest 64 is extremely useful, since it analyzes and verifies each one of the read and write sectors of our RAM, it also verifies the speed of the BUS and alerts us when any value is not within the normal parameters.

It is only compatible with 64-bit systems, so you should take into account this small limitation before installing it on your system.

4. Unigine Superposition

This program is specially designed for gaming computers, since it focuses on analyzing the performance of the graphics card, the temperatures offered by the cooling system and the voltages delivered by the power supply.

In addition, it tests the graphics card, subjecting it to a 3D scene that will make the graphics components work at 100% of their capacity to detect malfunctions.

This useful program has a trial version and another one in which you must purchase a license to access all the advanced options for testing and troubleshooting your computer.

5. HD Tune

HD Tune is a really useful program when it comes to detecting faults in the operation of your computer. Its focus is on detecting faults especially in your computer’ s hard disk .

Through this program you will be able to obtain extremely useful information related to your hard disk, since many of the most common failures related to the slowness of your computer have to do with a malfunction of the hard disk.

Through HD Tune you will be able to see the S.M.A.R.T. (Self Monitoring Analysis and Reporting) status of your hard disk. (Self Monitoring Analysis and Reporting) status of your disk, so that you can detect disk failures in advance.

You can download the trial version from its official page and, if you wish, buy a license of this useful program.

What components to test in a computer?

In a computer there are a huge number of components that can fail and cause it to work improperly or stop working completely. It is for this reason that we must know which are the vital components, so that we know where to look for the main failures before taking it to the technical service.

Next, we will mention which are those components that you should test as a priority when your computer presents an error.


The processor or Central Processing Unit (CPU) is in charge of performing all the arithmetic-mathematical operations that make our computer interpret the orders we give it through the peripherals we use to interact with it (mouse, keyboard, touch input).

If the processor has some kind of failure such as overheating due to problems in the cooling system, the system in general will be affected.

RAM Memory

Random access memories or RAM memories, are responsible for our operating system to have a fluidity in the temporary storage. This is what allows us to work with several applications simultaneously without our computer getting stuck.

When these memories fail, we can face problems such as our computer not displaying an image on the monitor or applications getting “hung” frequently.

Graphics card

Graphics cards are the components that we can add to our computer to take care of all the video processing exclusively. Nowadays the popularity of graphics cards has been increasing, thanks to the world of video games.

These graphics cards have a complex design that must maintain a balance between graphics processing power, power consumption and temperature management, so it is very likely that they can fail. For these cases it is necessary a good testing program that gives us detailed information about the performance of our graphics card in real time.

Storage Units

Storage units have a wide range of models and brands, but basically they all have the same function: to store information. It is normal that, by daily use, computer viruses, problems with electricity in our computer and many other factors, these units fail.

So do not hesitate to apply a test to your hard drive or SSD when you notice that your computer is a little slow or does not load an application, it may be that the problem is being generated by this component.

Power Supply

The power supply is responsible for distributing electricity at an adequate voltage to each of the components of your computer. If this one fails, obviously some other component will also fail.

It is important to make sure that we have a power supply that guarantees that it will deliver the perfect voltage that each of the components of our computer needs, since, otherwise, these components can be overloaded with energy and suffer permanent damage.


The motherboard is the part in charge of integrating all the components of our computer, where all the devices that make up our workstation are connected.

There are thousands of components that work simultaneously in our motherboard, so there are also thousands of probabilities that something fails, fortunately most of the motherboards in the market are of excellent quality.

It is important to test from time to time our motherboard and keep its drivers properly updated, thus ensuring that everything is running smoothly.
