Pros Shows you all the right stats crucial to stress testing your PC. Automatic looping testing. Cons Computer may experience crashes when using it.

Pros Easy to use. It can be used to test CPU, memory, and graphics card. Shows important information about your system in a single window.

Pros Easy to use and very user-friendly. Shows all the information you need about your CPU in an easy-to-read chart. Comes with an easy-to-use interface and can be downloaded for free. The responsibility of the server is distribution of a group of stress tests to each client and to track their status.

It is also known as application stress testing. It is performed to fine tune and optimize the system. It is performed to discover defects where a system data blocks another system. It is conducted to discover defects in unusual conditions, for example a large number of users logging in simultaneously, or database goes offline when accessed from a website.

It is also known as exploratory stress testing. To conduct stress testing of an e-commerce app, a large number of users hitting the app is simulated. The number of users being simulated for testing would be much higher than average number of users visiting the app daily. These users are virtual and are programmed to do common activities, such as viewing products, adding and removing items from the cart, purchasing the product, etc.

The number of users is increased to the point, until the app crashes or fails and can no longer handle the traffic. The results of the tests are examined to discover bottlenecks or drawbacks in the system, performance improvement or optimization areas, recovery mechanism, etc.

The results shaped by LoadRunner are used as a benchmark. It simulates the real-world actions and determines the performance of the system or application by generating virtual load. Before stress testing the system, the most important thing to have is some sort of way to measure temperatures of the components in your system.

HWMonitor has a clean, easy to use interface and will provide real time information such as utilization, temperature, clock speed, and power usage of the onboard components. Download HWMonitor. Generally an uninterrupted 6 hour run of Prime95 indicates that the CPU is good and will not have issues over its usable lifetime. There are several options when using Prime95 to stress test the CPU. The most intense test is the Small FFTs stress test which stresses the CPU the most ensuring that any possible issues will reveal itself early on.

Download Prime If you own an Intel CPU based system, one of the best CPU stress testing tools actually comes directly from the company who manufactured your processor. This test can be set to run on a loop and the test can even be set to automatically shut itself down if the CPU overheats.

Along with the increase in difficulty, Cinebench R20 now also features the capability to set a minimum time for the benchmark to run, which turns the benchmarking tool into an incredibly tough CPU stress test that simulates 3D video rendering loads.

If you plan on using your PC for rendering video, 3D modeling, or photo editing, this test is definitely for you. Download Cinebench R AIDA64 is a very comprehensive full system diagnostic utility typically aimed at engineers, IT professionals, and systems enthusiasts.

Download AIDA Among the different components that are stress tested, one of the most forgotten components is the system RAM. Most system RAM that fails will tend to fail early on causing blue screens and inexplicable system restarts.

If any issues arise, large red letters will indicate that you should probably return your memory or if overclocking, you may want to back off those overclocks just a bit.

Furmark offers features such as benchmarking, video capturing, and report saving. It can run in both windowed and full-screen mode. You can also initiate the rendering manually by starting up FurMark and changing the settings as necessary to fit your needs.

Download FurMark. It is used to test and analyze the stability of graphic processors under extreme loads. It works by recreating conditions similar to playing a game and using your graphic processor at the same time. Modern graphics cards are built with an onboard processing unit or GPU that is designed specifically for these tests.

Download LinX. There are a few different types of testing tools that can be used for stress testing. Many heat issues are caused by the graphics card and CPU working too hard, so make sure to be careful of that. Overall, using a stress testing tool like Prime95 will allow you to see the performance hit that something as simple as an upgrade could have on your computer.

You can test your video card and CPU separately, or you can do both at once by combining stress tests. Here are a few frequently asked questions about stress testing which are generally asked by our readers.

The short answer is yes! Although it may not seem like it, every little bit helps. If your graphics card crashes while playing games, you could have a major problem with your hands. It would be a lot better to stress test the card first and see if there are any performance issues before you try to upgrade or buy a new one. This will give you the information you need to know about your hardware before spending money on it.

Many video card stress test programs include automated testing that does not require you to start up a program manually. The best way to do this is to install the video card stress test software after you have installed your motherboard drivers and reboot the computer.

The program will automatically start up the testing when your computer starts up and should be ready for an instant stress test. You are going to want to make sure that you look into this thoroughly before continuing.

You could have a faulty video card or bad RAM that is causing this, but you should also make sure to test out your motherboard and other parts of your system as well. If you are using anything else apart from the video card for a stress test, you should check to see if it is causing any problems at all. There are many different ways to do this, but the simplest method would be by using software like Prime
