"Blue screen of death" feature in Windows.

How to figure out what computer hardware is in trouble

Hardware problems? Many times our computer seems to be slow, various crashes happen suddenly, e.g. screens in Windows, browser crashes, or freezing of the entire system while watching a video. 

Since we have blocked a possible software problem, that is, some malware infection and our computer is clean (for details see the article below here), we must begin to believe that we have fallen victim to a "hardware failure", or else there is a problem with the hardware!

Our problem can come from some of our computer devices (ram, VGA, CPU, SSD, HDD etc). But how can we figure out what is due before we contact a technician or before we order something useless and unnecessary because we mistakenly believed something else?

Below we will do an analysis of how we can test each one ourselves of our computer separately, in our home!

Blue screen, looking for the error message.

Most blue screens you will encounter in modern versions of Windows may have been caused by hardware failures. The blue screen often displays information about the driver that crashed or the type of error it encountered.
For example, let's say you encounter a blue screen with an “NV4_disp.dll” error message. A quick one στο Google θα αποκαλύψει ότι αυτός είναι ο οδηγός για τις κάρτες της NVIDIA, έτσι τώρα μπορείτε να ξεκινήσετε από κάπου. Είναι πιθανόν η κάρτα γραφικών σας να έχει αποτύχει εάν αντιμετωπίσετε αυτό το μήνυμα σφάλματος.

Checking hard disks.

Hard drives have a built-in SMART (Self-Monitoring, Analysis, and Reporting Technology) feature. The idea is that he himself disk monitors itself and will let you know if it fails, providing you with some warning before it fails completely.

But this does not always work that way, it can fail even if SMART says everything is OK.
If you see any kind of “SMART Error” message, your hard drive is failing. You can use SMART tools to view its status information of your discs.

Disc Scan Tools:



Test your Ram.

Η αποτυχία της μνήμης RAM  μπορεί να οδηγήσει σε μια ποικιλία προβλημάτων. Αν ο υπολογιστής γράφει δεδομένα στην μνήμη RAM και η μνήμη RAM επιστρέφει διαφορετικά δεδομένα επειδή είναι δυσλειτουργική, μπορείτε να δείτε από κατάρρευση της εφαρμογών, μπλε οθόνες, διαφθορά του συστήματος , μέχρι και μη ολοκληρωτική λειτουργία του υπολογιστή σας.

To check your memory and see if it works properly, use the built-in Windows diagnostic tool. The memory diagnostic tool will write data to each area of ​​your RAM and read it again later, ensuring that your RAM is working properly.



You will open it simply by typing the word "search" in Windowsmemory"Or"memory diagnostic tool".

Another more sophisticated program (which I will not explain how it works) is memtest. It performs extensive analysis of memories, running through BIOS.

You can find it here.

System temperature control.

The high is the main reason for the destruction of our computer materials, that is why cooling is our main concern when "building" a computer. We can easily check the temperatures by installing the program below. Speccy will do a detailed analysis of all parts of your computer and inform you of any high temperatures.


Processor test.

Μπορείτε να χρησιμοποιήσετε ένα βοηθητικό πρόγραμμα, όπως το Prime95 για αυστηρό έλεγχο της CPU σας. Ένα τέτοιο εργαλείο θα αναγκάσει την CPU σας σε εκτέλεση υπολογισμών, χωρίς να της επιτρέπει να ξεκουραστεί, θα εργάστεί σκληρά και θα παράξει θερμότητα. Εάν η CPU σας ξεσταθεί αρκετά, θα αρχίσετε να βλέπετε τα or the system will crash.

Overclockers use Prime95 to ensure any cooling errors and to make sure the CPU is running cool and stable. It's a good way to check if your CPU is stable down hard work!


Test the graphics card.

The sensitive point of ! Graphics cards can also be hotbeds of trouble for balancing our system. The collapse of VGA can cause blue screens, freezes and general malfunction of our computer.

How can we control the operation of our graphics card? With the following program.


3DMark (Direct10).


Δεν είναι κάθε πρόβλημα υλικού εύκολο να εντοπιστεί. Εάν έχετε μια κακή μητρική πλακέτα ή παροχή ηλεκτρικού ρεύματος (πρόβλημα στο ), τα προβλήματά μπορούν να εκδηλωθούν μόνο μέσα από περιστασιακά περίεργα θέματα με συνεργασία με τα υπόλοιπα μέρη του υπολογιστή σας. Με λίγα λόγια, για προβλήματα μητρικής κ τροφοδοτικού, είναι δύσκολο να εντοπιστούν τα προβλήματα, αν δεν αντικατασταθούν πλήρως.

Finally, the best way to determine if an ingredient is defective is to replace it completely. For example, if you think your graphics card might cause a blue screen on your computer, pull the graphics card out of the computer and insert a new graphics card (possibly borrow one). If all goes well, it is possible that your previous graphics card was defective.

This is not easy for people who do not have desktops. Troubleshooting involves error testing, and switching components allows you to determine which component is really causing the problem.

This is not a complete guide to everything that could possibly go wrong and how to locate it - one could write a complete book on hardware debugging and still not cover everything. However, the above tips will give you some places to start dealing with the most common problems.
