Best Free Computer Diagnostic And Repair Software

[Glynis Waughtal]

Perhapsthe best plan is to scrap any low value boards; do a solder reflow of the rest so that they can all be done together and then do a desktop function check with CPU, stick of RAM, keyboard and monitor. Very briefly power them up and off as you may only have heatsink resting on CPU. If any function to BIOS then use them and scrap the rest. This approach will rapidly reduce your pile of motherboards.

Well, I just wonder how in-depth you want to go from a testing stand point. Once you go beyond physical inspection and possibly a diagnostic card, then things can get very detailed and intricate. Once you identify a failed component, are you going to repair it in-house? This might help to clarify an answer we can provide.

As a rough rule of thumb, consider your time to be worth about $100 - $150 per hour, maybe less, maybe more, but this is a good range if you want to be profitable. So if the motherboard costs $150 and you are troubleshooting for 2 hours, you already went double what it would have cost just to replace the motherboard with a new one out of pocket. However, much it seems like you should try to fix them, it is hardly ever worth it.

However, in the case where the board is expensive, or rare or a replacement is not even available at all, then someone may be willing to pay for troubleshooting and repair. With current shortages, there may soon be money in repair which was not available previously.

Computer diagnostics tools are pieces of software that give you the knowledge you need to be able to potentially repair your own computer. Some of these tools come built in to your operating system while others come from 3rd party software developers. Either way, these tools help save you time and money.

The first one on our list is built right in to Windows operating systems. The performance monitor gives you a quick view of vital information related your computers 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 is number two on our list. This diagnostic tool is more robust that 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.

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.

HD Tune Pro is a great tool for HDD and SSD diagnostics. This utility allows you to benchmark your storage device showing you the minimum, maximum and average transfer rates along with many other useful tools. The other features of HD Tune include detailed drive info, error scanning, & drive health. The pro version allows you to check the health status of multiple drives, offers folder usage info, secure erase, file benchmark, disk monitor, cache test & extra tests.

Computer diagnostics are meant to serve a vital purpose. They are important tools which work automatically, with very little effort necessary from the end user. They help you discover and fix problems within your hard disks and network configurations. Rather than manually searching for small, hard-to-find problems on your own, you can simply allow computer diagnostics tools to take care of your problems for you!

Without disaster recovery services, one single cybersecurity event, or system failure, can put your operations out of commission for weeks, affecting compliance, productivity, profitability, and customer experiences for years to come.

Whether you're a Windows newbie or a grizzled veteran, your system will eventually run into problems that aren't easy to diagnose. Before you call tech support, there are plenty of PC diagnostic tools you can try.

As with older versions of the operating system, Windows 10 and 11 have a Performance Monitor. However, unlike the older versions, this is now a standalone PC diagnostic tool. Check out how to open the Performance Monitor if you're not familiar with it.

By default, the Monitor only shows Processor Time, which displays how much of your CPU is being used at any given time. However, you can add more counters such as disk usage, energy used, paging file size, search index size, and more.

The Reliability Monitor is a lesser-known utility that's been around since Windows Vista. You can find it by opening Windows Search and typing "view reliability history." Despite the differing name, doing this will still launch the Reliability Monitor.

Here you'll see a history of your system and a timeline of events and errors that occurred during a given period. The blue line is an estimate (from 1 to 10) of how stable your system is over time. At the bottom, you can see which troublemakers are throwing errors, which you can look into to improve your system stability score.

Whether you're using a Wi-Fi or Ethernet connection, there's a good chance you're going to run into network problems eventually. Fortunately, there are plenty of Windows diagnostics tools that make troubleshooting your internet connection a breeze.

After the analysis, it will recommend a channel setting for you. It's not perfect, especially in crowded apartments and dense cities. However, it can boost your Wi-Fi speed and reliability significantly, so it's worth trying.

You can use it at home to see how many devices are connected to your network (to check if anyone is mooching off your connection) or find the IP address of a specific device (such as your smartphone). It allows you to initiate remote shutdowns as well.

When checking your PC for faults, it's easy to overlook your storage device even though storage drives are one of the most important pieces of hardware to keep healthy. You can buy a new processor, RAM, or GPU, but losing personal files carries a cost you can't cover with cash.

Ever wondered if your hard disk drive or solid-state drive was in good condition? While there are warning signs that your SSD is on the way out, you'll ideally want to identify a failing drive before these issues surface.

WinDirStat scans your data drives and tells you how much space is used up by various folders and files, all displayed in a neat tree-based hierarchy and a detailed graph view. The bigger the file or folder is, the larger the square is on the graph.

Through this utility, you can also scan any partition for potential errors on your disks. To do this, open Disk Management, right-click the partition you want to scan, then go to Properties > Tools > Check. You'll need to use an administrator account to do this.

As apps become more memory-intensive, it's more important than ever that your computer's random access memory (RAM) is still healthy. If you're encountering RAM issues, try these tools to diagnose the problem.

The Resource Monitor is a Windows diagnostic tool that offers a full overview of your system. Traditionally, you'd have to launch it through the Task Manager, but now you can open the Resource Manager as a standalone tool.

The Resource Monitor is an advanced way to view real-time data about your system and is typically used in conjunction with the Performance Monitor. If you want to keep an eye on how processes use your computer's hardware, then the Resource Monitor is a great place to start.

Windows has a built-in tool that can test your RAM modules to confirm they're free of errors. It's called the Windows Memory Diagnostic, and can give even the best computer diagnostic and repair software a run for its money.

Does something look strange on your screen? If you notice a small black dot on your monitor that isn't dust or grime, it might be a dead pixel. Fortunately, some apps can help dislodge a saveable dead pixel.

Using JScreenFix is a great way to fix a stuck pixel on your monitor. It flashes hundreds of different colors every second around the area of the screen containing the stuck pixel. This should unstick the pixel after about 10 minutes.

Unfortunately, there's no guarantee it'll work. Sometimes a stuck pixel will be stuck forever due to a physical defect in the screen. But JScreenFix has a success rate of over 60 percent, so give it a try if you have a stuck pixel of your own.

PixelHealer, while free, is still one of the most highly effective software diagnostic tools you can use to revive a dead pixel. Unlike Jscreen Fix, this utility does require a download, but the file size is less than 100KB, so it shouldn't take much time.

Not many people know about AdwCleaner, which is a shame because it's fantastic and deserves more recognition. It's a simple malware scanner, but it's fast, efficient, and free, which is all anyone can ask for.

It's mainly designed to target malware that comes bundled with installer files, so it detects adware, toolbars, unwanted programs, browser hijackers, etc. Scan results are sorted as services, files, DLLs, scheduled tasks, registry entries, and more.

Note that Malwarebytes comes in both Free and Premium versions. The Free version is great and is more than enough for most home users. However, the Premium version is worth the money if you fall in love with Malwarebytes.

ClamWin may look primitive, but don't let that fool you; it's a powerful tool to have in your digital toolbox. The scans can take a while, but they detect pretty much everything, so the trade-off is worth it.

Best of all, ClamWin is open-source, unlike the above-mentioned alternatives. This means that the code is available for anyone to review, so you can be certain that no hidden surprises are lurking within the app.
