Huge List of Computer Stress Test Software [Rugged Computing]

Update 05/14/2020: Check out our comprehensive blog post on MIL-STD-810 temperature testing procedures and Mil-Spec temperature ranges to learn more about how we subject our rugged computers to environmental stressors.

In this blog you'll find a relentless list of computer stress test software (FREE & PAID) which benchmarks and/or diagnoses different components of a rugged computer system.

As a bonus, I've also listed popular hardware monitoring tools that you can use to diagnose any computer related issues.

A lot of these tools are used by professionals in the rugged computer industry to help identify issues with computer systems. So I thought to share them with you - all in one place.

For your convenience, I've distinguished stress test software from hardware monitoring tools with two asterisks(*) next to the name.

What types of stress test software are we talking about?

• CPU Stress Test Software
• GPU Stress Test Software
• RAM Stability Tests
• HDD/SSD Utility Software
• Computer Temperature Tests
• Network Diagnostics Tools
• Computer Monitor Tests
• Computer System Benchmarks

Note: Some of the tools listed are able to test more than one component of your computer system.

Without further ado - I present the Complete List of Computer Stress Test Software for 2019. Starting with...

CPU Stress Test Software

PassMark - BurnInTest™** (FREE & PAID)

If you want stress test software of a computer's subsystems tested simultaneously, this is the tool for you. Not only is it for testing but also troubleshooting and diagnostics. It saves you a lot of time by being able to run multiple tests at the same time. The UI is user friendly and comes with bunch of other useful features at the paid level.

powerMAX** (FREE)

In short, it is a CPU and GPU burn-in test. It can test the CPU or GPU individually or both at the same time. It does not provide stability or performance scores, therefore don't consider it a benchmark tool. It is a powerful tool and does, however, reveal the weaknesses of some of the computer's components. Be careful though, it may cause irreversible damage to your computer, so proceed with caution and use at your own risk.

Intel® Processor Diagnostic Tool (FREE)

Although meant for anyone with an Intel® CPU, this tool, developed by Intel® is a diagnostic check that verifies the CPUs operating frequency, tests numerous features on the processor, and performs a CPU stress test. It is compatible with multiprocessor systems and requires Win7 or later to run.
