OcCT
1.
Test every component of your computer using 6 powerful, efficient tests! CPU, memory, GPU, VRAM, power supplies, every critical component can be tested. OCCT is a free tool for measuring the performance and stability of your computer. It has 4 built-in test panels targeting CPU, GPU and power.
It also monitors temperatures, voltages, fan speed, as well as memory usage and frame rate (FPS) (3D test). It has the most accurate error detection algorithm for CPU and GPU.
Even though components are currently well protected from overheating, OCCT includes another layer of safety by allowing you to set a maximum temperature limit. OCCT's CPU test is the most advanced out there.
Capable of detecting stability issues in seconds, it can perform per-core testing and allow you to adjust the instruction set used and data size.
Victoria HDD - SSD
2.
Free program designed to diagnose and repair hard drives, SSD drives, memory cards, and other drives in Windows. It is a remarkable, quite useful program that monitors the performance of your hard drive and gives you solutions in case of problems.
You can examine your disks for various problems and if any are found then the application has the ability to repair them. It can analyze and display details about your storage media, including disk size, serial number, and more. The application may redirect, restore, ignore or delete the data in the sectors that have errors or delete the data and correct it.
A powerful HDD surface scanner is built into the program, which allows you to diagnose the drive for bad areas, defects and interface errors. It is able to test almost all discs regardless of their type. A feature of the scanner is the use of special algorithms for automatic adjustment of time limits and block size, which allows you to efficiently scan both slow and fast disks.
The graph is based on 188 points, evenly distributed over the tested volume of the drive. The result is visually and numerically identical to a full 4-hour scan, except for finding defects.
It is used to study known good drives to measure the main parameters: speed at the beginning and end, access time, behavior in different block sizes, as well as to compare different devices in terms of technical characteristics. Charts can be saved to files and loaded back into the program. (The website is in Russian language)
CheckFlash
3.
Looking for a simple, free, reliable tool to measure the speed of your flash drive while also checking its integrity, you can trust Check Flash. This is a simple, portable application, through which we can measure the write and read speed for any USB stick and at the same time we will check if there is a problem.
To get started, download the program, unzip it and run the application, select your stick and press Start to begin testing. The user can choose one of the three types of access types that are available.
Each type of access allows you to perform specific tests and provides useful data. After the check is complete you will see the average read and write speed for your stick and information about any errors found on your drive.
CAUTION : The app allows you to run all the tests listed above as well as the full wipe test. Make sure to backup your data because the device needs to be formatted after the testing process.
CheckDrive 2023
4.
CheckDrive is a modern software offering you an easy way to check your computers hard drives for errors. It displays information about your drives in real time and monitors your hard drive values throughout its operation and notifies you immediately after any errors occur, so you'll know right away if something goes wrong with your hard drive.
To check if a hard drive has errors, run the application and you'll see a question mark next to each drive, which means the drive hasn't been checked yet. Now click on the Check button and if everything goes well you will see the indicator indicating that your disk has no problem. It will also work for SSD drives. To use the application you must register.
MemTest86
5.
Defective RAM can cause many problems on a computer, including corrupted data, crashes, and unexplained behavior. Bad RAM is one of the most frustrating problems as the symptoms are often random and hard to detect. MemTest86 however, is a great diagnostic that can help diagnose faulty RAM (or rule it out as the cause of system instability). Therefore it is often used by PC repair shops, overclockers and computer manufacturers. It boots from a USB flash drive or CD and checks the RAM on your computer for errors using a series of comprehensive algorithms and test patterns
Video Memory stress test
6.
Video Memory stress Test is designed to test the RAM for your graphics card. Similar to Memtest86+, it will read and write the data to every part of the RAM on your graphics card and allow you to fully test the VIDEO RAM (DirectX access).
It is probably the best way to check the stability of the graphics card after overclocking. There are three types of tests (DirectX, CUDA and OpenGL), plus a number of options. You can also choose the size of the surfaces, or if you want in case the program finds an error a sound will also be heard at the same time. A full test takes about 30 minutes, however you can choose from the test set controls with a much shorter time.

Start by pressing the first START selecting the colors one by one and observe where the problem is on your screen (to exit press ESC), now in case you find a problematic Pixel press the second START and move the window with the colors that flash to the spot with the problematic Pixel.
Let it work for some time, now if everything went well the problem will be fixed. For the application to work properly, run it with administrator rights.
HardDisk Validator
12.
This is a simple utility designed to help you find out if your hard drive has reached the end of its life and if it is possible to repair any bad sectors. However, before we continue about the program let's do a little recap.
What is a bad sector? As hard drives are known to write data in block units (sectors), every time a hard drive updates a sector, it also updates a checksum (stored immediately after the sector data).
When a sector is read from your hard drive, it is expected that the sector checksum will match the sector data, if it does not, then most likely bad sectors have been created.
The appearance of bad sectors can come from either a power outage during recording or from some other malfunction of the hard disk for some other reason such as falling, mechanical damage and others.
The question that arises is this: Can bad sectors be repaired? NOT always, however, if the data stored in the sector is simply invalid, but your hard drive is working properly, you can repair the bad sectors that have been created.
However, before you start you should first see if your disk has bad sectors. For this purpose, run the HardDisk Validator application, select Read and press Start to start the diagnosis.
If something appears to be wrong with the drive, it is best to back up the data and use the "Write + Verify" test, which will erase all data on the drive.
CAUTION : If you use a single disk to boot your operating system you can run the scan to see if your hard disk has bad sectors, however, it is recommended that you avoid trying to repair it if it is the one that hosts your current operating system . In this case, what you can do is disconnect your hard drive and connect it as a second one, to another computer and run the program there.
Possibilities of the application
- Read: It will scan the entire surface of the hard disk to detect bad sectors.
- Read + Wipe Damaged + Read: Scans the entire surface of the hard drive to find bad sectors, if bad sectors are found, they will be replaced and re-read to make sure they were successful this time around.
- Read + Write + Verify + Restore: The program will write a test template to disk, verify that the template was successfully written, and then restore the original data.
- Write + Verify: The program will write a test template to disk and verify that the pattern was successfully written. (original data will be lost).
