Understanding the Basics: Essential Diagnostic Tools

PC users utilize diagnostic tools to find and resolve any problems with their computers, including malware, viruses, and issues with drivers and external devices.

The two main categories of computer diagnostic tools are software and hardware:

  • Hardware-based diagnostic tools include: PSU tester, voltage detector, network tool etc.
  • Software-based diagnostic tools include: OS scanners such as antivirus/malware scanners, OS diagnostic utilities like error checking tool which is similar to error-checking utility in Windows, S.M.A.R.T status checker for hard drives etc.

Digital Multimeter

A digital multimeter is a device that can take many types of measurements. It tests the integrity of circuits and the quality of electricity in computer components. A digital multimeter displays the information on an LCD or LED screen.

Power Supply Tester

A power supply tester is a simple electrical device that is connected between a power supply and a computer. It leads to the motherboard socket for testing voltage levels of different parts properly.

Loopback Plugs

A loopback adapter, also called a loopback plug, tests the basic functionality of computer ports. The adapter is specific to the port that you want to test.


Your computer completes a Power On Self Test, or POST, every time you turn on your computer. POST performs basic diagnostics on your computer’s memory and hard drives, checks for the presence of a keyboard and mouse, and tests the clock and other system settings. POST resides in a small, permanent memory area called BIOS, which stands for Basic Input Output System; this contains compact, simple programs the computer uses when you first turn it on. If a problem exists with the computer’s hardware, POST signals this through coded audio beeps. Though hardware makers have produced different versions of POST over the years, they all ensure that the computer works correctly before it starts the operating system.

Cable Tester

Cable testers verify the electrical connections in a signal cable — confirming things are wired correctly between the ends of the cable. If there is a broken connection, the Hosa CBT-500 Cable Tester will let you know exactly where that connection is, which may have a simple solution such as resoldering a single contact point, saving you from throwing out a perfectly good, salvageable audio cable. Diagnosing these issues can help save a lot of headaches in the long run.

Getting Hands-On: Hardware Repair Tools

Hardware or software can be used as tools for computer maintenance and repair. Hardware tools are actual tools, like as screwdrivers, that are used to fix the computer’s internal parts. On the other hand, software maintenance instruments are employed in the upkeep and restoration of system programmes.

Among other things, pliers, tweezers, multimeters, screws and nut drivers, and cable clippers are the primary tools for maintaining computer hardware. They serve a multitude of purposes, depending on the instrument. Among its many unique uses, tools can be used for holding, cutting, tightening, and loosening.

Screwdriver Set

Screwdrivers are the workhorse of hardware. A good one will be tough and comfortable, with a well-designed handle that allows you to line up screws in tight spaces without hassle or risk of dropping them! Many modern screwdrivers have interchangeable bits so it’s easy as pie for any project size and magnetized tips so that tiny screws can be held in.


Pliers are versatile tools that can be used for a variety of pulling, gripping, twisting and cutting jobs. Plier types include needle-nose or long-nose, which help you in tight spaces and when working with tiny components like jumpers and switches; diagonal cutters to slice through the insulation on wires etc., so it’s important not only know the difference between them but also have one tool for each function!

Anti-Static Wrist Strap

If you want the peace of mind that comes from knowing your sensitive electronic components won’t fry in an instant, then get yourself an anti-static wrist strap. The wrist strap protects your components by limiting or discharging the amount of static electricity that naturally builds up around you. If anything were to happen while working on a computer, at least there is some protection for those expensive electronics from accidental hand contact!


Tweezers are an essential tool for anyone who wants to get into hard-to-reach spots with their computer. There are two considerations when using the tweezers: first, they need a stable grip and second, if they are spring-loaded, to make sure there’s enough spring force so that it won’t close on its own during use. Some tweezers are also ESD proof meaning any electro-static discharge won’t affect picked-up components.

Other tools might include:

  • Wire cutter and stripper: it is used to cut the wire and strip the insulation material to uncover the wires. They can be used to strip cables when terminating network cables.
  • Multimeter: it is used to measure multiple electrical values such as voltage, ohms, and current. The best is a digital multimeter which has an LCD display.
  • Memory module tester: it is special equipment that tests main memory (RAM) functionality.
  • Pliers: Used for cutting and gripping or holding parts. Types include needle-nose, slip-joint, and cutting piers among others.
  • Soldering rod: it is used to remove solder from components and fix others. The rod is used during repair to fix components on the motherboard.
  • Flashlight: Used to light up areas that you cannot see well. It can be used at the repair table.
  • Cable crimper: Used to attach connectors to wires. The most common is the network cable crimper that terminates the RJ45 to the ethernet cable.
  • Soft cleaning cloth: Used to clean computer components without scratching or damaging them.

Data Matters: Data Recovery Tools

If you ask anyone who has lost data if it was a pleasant experience, they will tell you that losing important files is a very stressful one, regardless of whether it was caused by cybercrime, hardware or software failure, or inadvertent deletion.

Businesses now use cloud backup or hard discs to store a large amount of their critical data. It’s possible that you regularly store everything on an external hard drive or a USB stick.

There are a number of data backup software options, and disk cloning software that can make the process of data recovery relatively simple and easy to do. Still, if you don’t have anything like this in place then in the event of a hard drive crash or corrupted drive you will need dedicated data recovery tools to help restore your missing files and folders.

It pays, then, to have a robust data security plan for your organization. Data recovery software or data recovery services should be an integral component of this plan.

Fortunately, there are several high-quality data recovery packages available to businesses. In the event of partial or complete data loss, these software packages enable you to recover as much data as possible and limit the negative impacts. Even if you use a data backup service, you should still have a data recovery plan in case the worst happens.

Below are the data recovery tools you should have handy:

External Hard Drive Enclosure

At its simplest, a drive enclosure is a metal or plastic housing designed to cover and protect a disk drive from damage. Drive enclosures can house single or multiple drives and also contain a method for connecting the drive to a host computer. Drive enclosures are typically thought of as stand-alone devices that provide power to the drive(s) and one or more types of interfaces (USB 3.0, for example). As such, a drive enclosure is synonymous with an external drive used for storage expansion for a laptop or desktop computer.

Drive enclosures can also be removable devices designed to insert into (and be removed from) frames and carriers that are built into host devices, whether that host device be a computer workstation, laptop, or some other device used to ingest or read data such as a digital projection system in a movie theater.

A common example of a drive enclosure is a stand-alone external drive used as additional data storage for a laptop or desktop computer. What you see when looking at an external drive is a combination of several items: the external ‘enclosure’ (typically made of plastic, sheet metal, or aluminum), the unseen internal disk drive or SSD, and one or more ports, which connect the drive via cable to a computer. The enclosure also houses electronics used for communicating between the disk media and the host computer.

Data Recovery Software

Your data is shielded from loss by software corruption, hardware malfunctions, and user error by data recovery software. Others make use of it to restore data that was erased unintentionally from a deleted file, natural disaster, malware assault, or power loss.

Regardless of the cause of your data loss, you want to select the finest solution for your requirements. This list of the top data recovery programmes on the market was created after hundreds of data points were examined. Data recovery software is used by businesses to guard against data loss.

Cracking the Code: Software Diagnostic Tools

Software known as computer diagnostics tools provides you with the information required to maybe fix your own machine. While some of these tools are developed by third-party software developers, others are integrated into your operating system. In any case, these tools save you money and effort.

One can use computer diagnostic tools. scan the hard disc of your computer, look for faults in your RAM, monitor the CPU temperature, and provide you with details on any additional devices that are linked to it. These tools are designed to identify issues that might be interfering with the regular operation of your computer. After an issue has been identified, you can schedule a repair.

  • Windows Performance Monitor

The first one on our list is built right into the Windows operating system. The performance monitor gives you a quick view of vital information related to your computer’s hardware. From here, you can check out your CPU, Memory, Disk info and Ethernet information. You can use Performance Monitor to examine the effects of your running applications in both real-time and by collecting data to check out for later analysis.

  • Windows Resource Monitor

Windows Resource Monitor is number two on our list. This diagnostic tool is more robust than Windows Performance Monitor. It is better suited for tracking individual aspects of CPU, Network, memory and disk usage. This tool gives you an in-depth look at what processes are affecting your CPU, how much memory is being used what is using it, individual process disk activity and network information like current TCP connections and what processes are listening on what port.

  • Open Hardware Monitor

Open Hardware Monitor is a free open-source application that runs on Windows and Linux systems. This diagnostic tool monitors your computer’s temperature sensors, fan speeds, voltages, load and clock speeds. If your computer is shutting down by itself, hanging or crashing, this tool can come in real handy by telling you that your system is overheating or the fans aren’t working properly.

Speccy is another great computer diagnostic tool. This application gives information on just about everything including software, hardware, peripherals, disk info, graphics & network data. Its easy to use layout make troubleshooting and maintenance a breeze. Great application to start with when you are looking for specific info about your computer.

Antivirus and Anti-Malware Tools

Antivirus and anti-malware are powerful cybersecurity tools. Both can protect you from malware attacks and remove dangerous files from your devices, but they serve slightly different functions.

  • Antivirus

Antivirus is cybersecurity software designed to prevent, detect, and remove viruses from computers. Antiviruses monitor programs for unusual behavior, check new files against known malware databases, and quarantine threats before they can cause damage.

You can install an antivirus program on most systems, including computers and handheld devices like phones and tablets.

  • Anti-malware

Anti-malware is the umbrella term for software designed to protect systems from malware (ransomware, spyware, adware, and other malicious software). Anti-malware software can prevent new malware from being installed on the system (for example, by scanning files while they’re being downloaded) or detect, quarantine, and remove existing malware.

Anti-malware software and antivirus overlap in many ways, and they cannot be defined as being entirely separate. However, there are some features that are more likely to be found in anti-malware than in antivirus tools, which helps to create some distinction.

You can go with a solid antivirus like AVG, a budget-friendly software, or Malwarebytes, which has been a trusted name for many years. 

Keep in mind that the best antivirus software doesn’t have to be the most expensive. Programs like TotalAV, which is our budget antivirus pick, and Avast’s free antivirus still offer excellent protection. These programs won’t interrupt your workflow and have been around for years, so they’re some of the more trusted products. They also won’t break the bank!

You could opt for a program like Adaware or Spybot Search & Destroy if you want to check out anti-malware tools. These are two of the popular programs often purchased. Ad-Aware comes with a webcam blocker, so hackers can’t watch you while you’re online. Spybot comes with several different features, like rootkit scans and antispyware tools.

Disk Cleanup and Optimization Tools

Whether you are running Windows 10 or Windows 11, a computer’s general performance will slow down after it has been used for a while because of frequent data storage and excessive starting items. To optimize your PC’s performance and clear up your hard drive, you’ll need to use a PC cleaner and optimizer utility.

These days, Windows comes with a large selection of system care and cleaning applications. Selecting the appropriate system tool is our first concern.

System Monitoring Utilities

System monitoring involves the continuous monitoring of an infrastructure – aka an IT system – by an IT manager. It includes the monitoring of CPU, server memory, routers, switches, bandwidth, and applications, as well as the performance and availability of important network devices.

Many sysadmins use the command line for certain inquiries such as whether or not a device is available. Many device manufacturers also offer their own monitoring tools, some of which are free of charge. However, unlike PRTG, neither of these solutions will provide you with an overview of your entire IT system. What’s more, with our network monitoring system, the first 100 sensors are free and never expire. You can also access the alarm and all other features for as long as you like. PRTG can therefore be used as free monitoring software.

There are lots of paid monitoring tools on the market. Sysadmins often compare PRTG with monitoring software such as ManageEngine, Zabbix, Solarwinds, and WhatsUpGold. The open-source tool Nagios is yet another option. Many IT managers also look for alternatives to their existing tools and come across PRTG.

Connecting the Dots: Networking Tools

We live in the world of the internet. Every single one of our works is dependent on the internet and its applications. And, when we are discussing the internet, there are two forms of options. You have the wired network and the wireless network. While the wireless networks allow you to connect to the Wi-Fi via routers, modems, etc., the wired networks use the switch, bulb, etc.

While it is easier to connect devices to wireless networks, the same isn’t the case with wired networks.

  • 1. Cable Stripper

Well, this is a matter of common sense. Given that wired networks use such thick bands of wires for transmitting the signal, it isn’t surprising that you need access to all the best quality cable strippers to open the wires and get the work done by that. They terminate the networking cables and allow the professionals to cut the wire according to their needs and the length they would use. The stripper also helps in removing the wire shielding.

  • 2. Cable Tester

Another important tool that is a must-have is the cable tester. More than its functionalities, this one has potent benefits in ensuring safety for the person working with the power and the electricity. It detects leaking power and electricity through the wires to ensure that there are no risks involved during the work. The cable tester also determines the continuity of the current flow in the wire. The process of using the cable testing is easy. All you have to do is take out the cables from the RJ45 connectors and then run both ends of the cable through the tester to determine the latency and the Readings.

  • 3. Wire Crimper

Next up on the list of the best networking tools needed for networking work is the wire crimper. This has a very similar function to the Cable stripper. However, unlike the strippers that are used for the thicker wires, the crimper helps in disconnecting the connect RJ45 connected using the twisted pair cables. Once the wires are stripped down, the professional can then lay them down and use them in the configuration that works the best for their connectivity or network involved.

  • 4. Tone Generator

Although you might be aware of the previous three, a Tone generator is a tool that not many individuals are aware of. Especially for beginner networking professionals, it will take you some time to familiarize yourself with this one. It is used for tracing cables from one end to the other. When you have so many cables available in the close vicinity, it does become quite difficult to trace the length of the cable and isolate them. The tone generator helps in finding the individual wires and segregating them from the remaining ones in the clump.

  • 5. Optical Time Domain Reflectometer

We are gradually stepping into the more professional and Hitech networking tools. The Optical Time Domain Reflectometer (OTDR) is quite a popular inclusion to the tool kit. This one is used to test out the potency of the fiber optic cables that are responsible for data transmission. The machine allows the detection any kinds of incongruence or other kinds of obstructions that are prevalent in the wire in general.

  • 6. Time Domain Reflectometer

Just like the OTDR, the Time Domain Reflectometer (TDR) is used to measure the potency of the coaxial cables and the twisted pair of cables. Unlike the OTDR that is used for measuring the optical fiber cables and their potential. The device is used by transmitting the signal using the cable and it is then reflected by the TDR. In case there are obstructions or other issues, the transmission process doesn’t happen as smoothly as you’d expect.

  • 7. Lighter Meter

Moving ahead to the next option in the list, we have the Lighter Meter. This is an electronic tool that has similar functions to OTDR. It is also used for measuring the optical fiber cables. However, this is a more beginner-friendly tool that doesn’t have the complicated functions and readings that you would otherwise get with the OTDR. The lighter meter’s primary function is to note down how much light is going through the fiber optic cable. This ensures to do so by sending light through the cable to look for interruptions down the middle.

Toolkit Organization: Keeping It Together

Doing computer builds and modifications is something that can expand the functionality and enhance the performance of a computer, such as replacing graphics cards. Sometimes altering the PC components is necessary when glitches are occurring. While under a professional these things could cost a few hundred dollars, with a good computer repair kit and some dedication, computer owners can do computer repair at home for much less.

Computer repair kits are a collection of different tools that are commonly used with computer components. They allow users to open up computers and remove or adjust the components when needed. However, most of these kits are not just for computers but the included tools can be used to work on many other devices and electronics such as phones and gaming systems.

  • UnaMela Precision Screwdriver Set Computer Tool Kit

No matter the type of PC task at hand, the UnaMela Computer Tool Kit has it covered. For a great price, this kit includes 123 different screwdriver bits to match almost any of the tiny screws on a computer.

This specific screwdriver has a rubber handle and rotating end to make for comfortable and smooth control. With up to 180° of room to bend around the flexible shaft can be attached to the screwdriver handle to reach those narrow places.

  • iFixit Pro Tech Toolkit

The iFixit Pro Tech Toolkit is the original electronic tool kit and is pretty well known in its category. Although it is a bit more of an investment than other computer repair sets on the market, the quality of this kit is worth it, especially for the professional who has to depend on the right tools to make a living.

The kit was specially designed to meet the needs of professionals and hobbyists. It was engineered with high-quality materials including 64 S2 steel screwdriver bits, a metal spudger, and an aluminum magnetic screwdriver.

  • Kaisi 70-in-1 Professional Electronics Repair Tool Kit

Computer repair can be a very tedious process, as one slip up and the whole PC could be damaged. That is why it is important to have a repair kit that is safe to work with such as the Kaisi 70-in-1 Professional Electronics Repair Set.

The included anti-static wrist strap will prevent any electrostatic discharge damage in the PC. The set also has an ergonomic press and push screwdriver handle. Additionally, users can depend on their tools to last through each repair thanks to the quality of construction.

The 56 bits and the metal spudger are made with high-quality stainless steel and have gone through lots of testing. One reviewer attested, “I am very pleased with the quality of this tool set.”

Hi-Spec 39-piece Electronics Repair & Opening Tool Kit

Not every user needs 100 different tools for their computer repair, which is why this Hi-Spec 39-piece Electronics Repair & Opening Tool Kit is a simple repair kit that focuses on just the necessary tools and avoids all the extras.

With things like needle nose pliers, electronic cutters, diagonal pliers, a wire stripper, a voltage test probe, and electrical insulation tape, this kit can be used for well beyond just computers, but other electronic work as well. With a nice carrying case, this makes a great kit for professional technicians as well as DIY-ers on the go.

One reviewer confirmed, “All the tools are sized just right and the included tools allow you to do a lot of different jobs.” Another user found that “other kits were mainly screwdrivers and I needed some diagonals and strippers. The tools are solid and appear to be above average quality.”

On-the-Go Repairs: Portable Repair Tools

Having the appropriate tools is important when fixing your computer. To undertake some serious repair work on fragile components like motherboards or graphics cards, you’ll need a solid set of screwdrivers and other pry-related devices; however, any old wrench will not do!

Almost anything can be opened with the correct tools, including cases that hold delicate parts like microphones or cameras. When dealing with any kind of repair-related problem, it makes perfect sense to use the right tools, such as plastic spudgers and specialty tool kits made especially for fragile components.

A great computer repair kit is a must-have for any tech. There’s no doubt you’ll need this in order to fix your PC at home, or if someone else has broken it and can’t figure out how on their own!

All of them should provide the basic tools needed to get started when fixing up an old laptop from scratch (or restoring one after a crash).

  • 1. Screwdrivers

Screwdrivers are the workhorse of hardware. A good one will be tough and comfortable, with a well-designed handle that allows you to line up screws in tight spaces without hassle or risk of dropping them! Many modern screwdrivers have interchangeable bits so it’s easy as pie for any project size and magnetized tips so that tiny screws can be held in.

  • 2. Tweezers
