Computers have seamlessly integrated into our daily lives, serving both work and leisure purposes. However, like any electronic device, computers may encounter operational issues, often related to their hardware or software. Specialized diagnostic software comes to the rescue, pinpointing the causes behind these disruptions. You can also utilize software to identify the sectors in your SSD or HDD. If any issues are detected, it is advisable to consider replacing the hard drive with a new one.
Hardware Glitches: The Culprits Behind Freezes and Bluescreens
Freezes, glitches, sluggish performance, and the dreaded “blue screens of death” are often linked to hardware malfunctions—issues within the computer’s components. Diagnostic utilities for PCs abound, ranging from versatile ones offering information and testing multiple components to specialized ones tailored to specific hardware. In this overview, we’ll explore the finest programs for diagnosing and testing PCs in each category.
Universal Diagnostics: AIDA64 Takes the Crown
AIDA64 stands out as the most versatile program for hardware diagnostics and testing. Evolving over two and a half decades under various names, the program has grown from a modest utility into a powerful tool. It not only provides detailed information about your PC’s hardware but also tests its performance and stability.
The user-friendly interface ensures accessibility, even for the uninitiated. The program’s myriad sections furnish information about your PC’s hardware and software. The “Tests” section allows diverse methods to assess processor and RAM performance, comparing results with other PCs from an integrated database. Each section of the program allows generating a text or HTML report with a simple selection.
Additionally, hidden tests are found in the “Service” menu, enabling tests for reading and writing speed of storage, cache memory levels of the processor, and GPGPU video card performance. The diagnostic suite also includes a monitor check—various tests to evaluate your screen’s image quality and detect any faulty pixels, along with a system stability test. Running the latter aids in verifying component stability under load, identifying failures, or overheating.
Beside AIDA64, another universal contender is its longstanding rival, SiSoftware Sandra. Like AIDA, Sandra divulges an immense amount of diverse information about your computer’s components and software.
Informational Tools: Insight into Your Hardware with HWiNFO
HWiNFO, while providing less extensive information compared to AIDA and Sandra, offers a unique feature—a sensor window. This window allows you to monitor temperature, voltage, and load indicators for all computer components, recording minimum, average, and maximum values. Tracking these values during workloads helps identify temperature and voltage deviations from permissible limits.
Processor Focus: CPU-Z and GPU-Z in the Spotlight
CPU-Z (https://www.cpuid.com/softwares/cpu-z.html) serves as a specialized program for interacting with the central processor. The utility delivers comprehensive details about the CPU and provides information about the motherboard and installed RAM.
GPU-Z, with a similar nomenclature, is designated for graphics processor information. Upon launch, the program displays essential details about the video card in use. Additional information about the BIOS model and graphical API support completeness is available in the Advanced section.
Both programs include a monitoring function for graphics card sensors. While running in the background, the program tracks changes in load and voltage, akin to HWiNFO. This feature is visually presented, allowing users to observe the fluctuation curve of each value within the software window.
Beyond Information: MSI Afterburner’s Dual Role
MSI Afterburner (https://www.msi.com/Landing/afterburner/graphics-cards) isn’t solely an informational utility. Primarily designed for graphics card parameter control, including overclocking with voltage adjustment, it also excels in displaying information about system loads as an overlay. This allows monitoring CPU and GPU loads, RAM and video memory usage, and temperature during gaming sessions. Afterburner’s ability to track these metrics through text or graphical representations makes it a favored choice.
In the realm of computer diagnostics, these programs offer a plethora of features, ensuring your PC’s health and performance are at their peak. Whether you’re uncovering hardware mysteries or fine-tuning your system, these tools have you covered.
OCCT: Stressing Various System Components
Specializing in stress testing diverse system components, OCCT offers numerous options for varying hardware loads. It goes beyond by providing features like automatic test termination upon exceeding specified temperature thresholds or encountering testing errors. OCCT allows both individual and comprehensive stress tests, enabling a thorough examination of your system’s performance under extreme conditions.
Furmark: Unleashing Stress on Graphics Cards
Designed to exert stress specifically on the graphics card, Furmark (https://geeks3d.com/furmark/) can heat up the graphic processor and its power subsystem to levels seldom reached during regular gaming. A stable performance under such stress implies the graphics card’s reliability, translating to fewer issues during gaming sessions.
MSI Kombustor: A Versatile Furmark Derivative
Derived from Furmark, MSI Kombustor offers additional options. Alongside the standard stress test, users can choose from various additional scenes creating similar stress conditions. These scenes come in different configurations, involving varying video memory, tessellation levels, and activated PhysX technology. The program also includes an artifact scanning option, aiding in the identification of potential video memory issues.
TestMem5: Evaluating RAM Under Load
For testing RAM under load, TestMem5 proves invaluable. Conducting a series of tests, the program notifies users of errors during the process. For advanced users, TestMem5 supports configuration files, allowing adjustments to the number and intensity of tests, offering more flexibility than default settings.
Storage Diagnostics: Assessing Disk Health and Speed
Hard Disk Sentinel: SMART Analysis for Disk Health
Hard Disk Sentinel evaluates disk health through SMART analysis. It displays health levels, total operating time, temperatures, and data write counts. The program can perform self-diagnostics on disks and test their surface for detecting bad blocks. CrystalDisk Info shares similar functionality, excluding testing features.
CrystalDisk Mark: Speed Assessment for Various Drives
CrystalDisk Mark, from the same developer, evaluates the speed metrics of different drives. The program measures reading and writing speeds, crucial for identifying anomalies in faulty drives.
Victoria: Comprehensive Testing for All Drives
Victoria is designed for a thorough examination of entire drives, whether it’s the hard disk surface or flash memory cells in an SSD. The program continuously reads or writes, analyzing response times of logical sectors and presenting them graphically. In case of a faulty sector, the program attempts to “repair” it by sending numerous requests, prompting the SMART system to mark the damaged sector for replacement.
h2testw: Flash Drive Testing Utility
Primarily known for testing flash drives, h2testw is versatile enough for various storage devices. The utility overwrites the entire storage with test data and then reads it back for verification. If any faulty sectors are detected, signaling potential data corruption, h2testw alerts the user—indicating the drive may not be suitable for storing critical information.
By employing these diagnostic programs, you can glean information about your computer’s components, evaluate their speed, and ensure stability. If your PC exhibits instability, an initial diagnosis can pinpoint the problematic component. Almost all programs listed are free, and the majority boast user-friendly interfaces, making them accessible even to those without extensive hardware knowledge.
