How to Check if Your Computer Can Withstand Tough Times
Learn how to make sure your computer doesn't let you down when you need it most!
Have you ever wondered if your computer can handle being pushed to its limits? Whether you play the most demanding games, work with video editing programs, or just want a reliable computer for your everyday use, there's a way to find out for sure.
In this guide, we'll show you how to do a "dress rehearsal" on your computer to discover its limits and ensure it's working flawlessly.
What does it mean to "stress" the computer?
It simply means that we give our computer the hardest job imaginable for a long time. It's like putting a car at maximum speed for hours to see if it can handle it. If the computer passes this "test", then it will work flawlessly in everyday use.
Why do you need to do this?
- Discover hidden problems: Sometimes the computer has problems that are not visible in everyday use, but appear when we push it.
- Check if the cooling is working properly: You will find out if the fans and cooling systems are doing their job well.
- Make sure of reliability: Especially if you use the computer for work, you want to be sure that it won't "let you down".
- Check the improvements you made: If you changed something in your computer (new memory, new fan, etc.), this is the way to make sure everything works together.
- Preparing for AI and Gaming: With the rise of artificial intelligence and modern games, your computer needs to be ready for heavy tasks.
Preparation: What to do before you start
Download a program to view the temperature
You need a program like HWiNFO64 (free and updated for 2025) or Core Temp to see how hot your computer is getting. This is very important for its safety!
Clean your computer from dust
Dust is the biggest enemy! Open the computer case and clean the dust from the fans with compressed air or a soft brush. Attention: Turn off the computer first and unplug the power cord!
Close other programs
Close all unnecessary programs (browser, music, etc.) to get a clear picture of the results. Also, temporarily disable your antivirus.
Update your drivers
Make sure you have the latest drivers, especially for your graphics card. Use Windows Update or GeForce Experience/AMD Software.
How to check the processor
The processor is the "brain" of your computer. Let's see how to check it with the best programs of 2025:
🏆 Prime95 (2025 Edition)
The most popular program for checking processors. The 2025 version supports all new Intel and AMD processors.
Cinebench 2025
Not only does it test the processor, but it also gives you a score to compare with other computers. It supports new AI workloads.
AIDA64 Extreme
A comprehensive tool that performs various checks and monitors temperatures automatically. It has a 30-day trial version.
⚠️ Be careful with the temperature!
When you do the test, monitor the processor temperature. If it exceeds 85-90°C, stop testing immediately! This means there is a problem with cooling. Modern processors of 2025 are more efficient, but cooling remains a critical factor.
Steps for checking:
Open the temperature monitor program that you downloaded earlier.
Open the control program (e.g. Prime95) and select "Torture Test".
Let it run for 15-30 minutes and monitor the temperature constantly.
Check if the computer remains stable - it should not close or display a blue screen.
How to check RAM
RAM holds the data that the computer is currently using. With the demands of 2025 (AI, 4K gaming, multi-threaded applications), RAM is more important than ever:
🏆 MemTest86+ v7 (2025)
The new version of the most trusted memory testing tool. Supports DDR5 and new memory technologies. Runs from USB before Windows starts.
TestMem5 + Extreme Config
Faster option that runs within Windows. Ideal for quick checks. There are special settings for DDR4/DDR5.
Windows Memory Diagnostic
It's already on your computer! In Windows 11 it has been improved and better supports new memories. Just type "mdsched" in the Start menu.
How to do it:
Choose your preferred toolFor beginners, Windows Memory Diagnostic is the easiest.
Let the control run. For a full test, it takes 4-8 hours (you can leave it overnight). New DDR5 memories take longer.
See the resultsIf it finds errors, you may need to change the RAM or reduce its speeds.
🚀 New Challenges: Control for AI and Gaming
2025 has brought new demands. Test your computer with these too:
🤖 AI Workloads
use it blender benchmark ή 3DMark CPU Profile to see how your computer handles artificial intelligence tasks.
🎮 Ray Tracing Gaming
If you have an RTX 40 series or Radeon 7000 graphics card, try this 3D Mark Port Royal for ray tracing.
🛡️ Important safety tips
- Don't leave the computer while the test is running - monitor the temperatures!
- Only use well-known and trusted programs from official websites
- New processors (Intel 15th gen, AMD Ryzen 8000) have better heat management, but your caution remains
- If you see strange temperatures (above 90°C), stop immediately!
- A 6-8 hour check is enough - it doesn't need to run for days
- If the computer shuts down by itself, stop - there's a problem!
What do the results mean?
✅ Perfect! The check was successful!
If your computer passed the test without any problems, congratulations! Your system is stable and ready for the demands of 2025. You can use it for gaming, AI, video editing, and anything else!
⚠️ We found some problems
- The computer shuts down by itself: Possible cooling or power supply problem
- Blue Screen of Death (BSOD): Problem with RAM, processor, or drivers
- Excessive temperatures: Need better cooling or cleaning
- Memory errors: The RAM may have a problem or be running too fast
- Termination due to thermal throttling: The processor reduces its speed due to heat
❓ Frequently Asked Questions
How often should I do this check?
It doesn't need to be done often! Once when you buy the computer, once if you make any upgrades, and once if you suspect problems. With new technologies, computers are more reliable.
Is it dangerous for my computer?
No, if you do it right! Modern processors have protections that shut them down if they get too hot. That's why we monitor temperatures.
What's happening with DDR5 memory and new processors?
New technologies are more resilient, but they also require more specialized tools. Make sure your programs support new technologies.
What should I do if I find problems?
Don't panic! Many problems are easily solved: cleaning dust, changing thermal paste, updating drivers, or simply lowering RAM speeds. Consult a technician for serious problems.
📝 Conclusion
Testing your PC's endurance is even more important with new AI technologies, ray tracing gaming, and increased application demands. With the right tools and a little care, you can ensure your PC will serve you reliably for many years to come. Remember: Safety first! Always monitor temperatures and stop if something goes wrong.
