test pc hardwareGood PC ownership is a lot like good car ownership. You do more than just use it, you learn something about how it works. You don’t need to be a PC technician or a mechanic, but you should be able to identify certain signs of trouble so you can get your rig in for maintenance. Unfortunately, testing your PC for failing hardware isn’t quite as hands-on and easy to do as checking your car for worn tires or dirty oil. Fortunately, you have access to the minds of and a wide web of free tools to test for failing hardware. Or, more appropriately, to check on the health of your hardware.

If you’ve ever opened up your computer, you know there is a lot of hardware in there, a lot of potential points of failure Every Computer Dies In The End: Learn What Parts Can Fail, & What To Do About It Every Computer Dies In The End: Learn What Parts Can Fail, & What To Do About It Most computers develop problems over time. Learning what they are and how you can deal with them is important if you don't want to be paying through the teeth for professional repairs. Don't worry though... Read More . That’s how pessimists and engineers talk. However, there are certain points which are more prime for failure than others. Those pieces of hardware that either generate heat or have moving parts tend to be the ones that fail most often.

Now that you’re thinking along those lines, you’re probably thinking of fans, hard disk drives, and CPU’s or GPU’s. You’d be correct that those are probably the most common points of failure in a system. RAM also tends to fail too, since it is constantly being written and re-written to, or flashed as they say in the electronics world. Solid-state memory can only handle so many flashes before it begins to fail, and this also applies to solid-state hard drives.

Windows 7 & 8

Windows 7 and 8 have some great utilities already built into them. In fact, there is so much in Windows that most of us don’t even know about 8 Hidden Tools In Windows 7 You Still Might Not Know About 8 Hidden Tools In Windows 7 You Still Might Not Know About Windows 7 is by no means a new operating system. This why I was doubly surprised to realize that there are still some hidden tools in Windows 7 I did not know about. Even if... Read More , that we go and buy software that already does what Windows does. Even so-called power users can get caught in this trap. It’s almost like having a Swiss Army knife with so many blades, that we just go out and buy a normal pocket knife.

Resource & Performance Monitor

Both of these operating systems have a built-in diagnostic tool you might not have ever known about. To access the Resource and Performance Monitor, simply hold down your Windows key and press the letter R. A new window will open and you can type in the command perfmon /report, then click on OK.

A new window will open and will begin collecting data. This process takes a minute.

Then you’ll get a report with more information than you or I will probably ever know what to do with. The main report that you want to look at though is the Diagnostic Results – Warnings and the Resource Overview. The Diagnostic Results Warning only comes up if there are some warnings.

What’s nice about this is that there are links to more information about the situation and how to remedy it.

The Resource Overview is going to give you the red-yellow-green light overview of the major parts of your system. This gives you an instant overview of the health of these major components. Apparently my computer could use some more RAM, as I have a red light on my Memory. Or I could close a few applications I don’t need running right now.

There are several other reports available from the Performance Monitor, but most of those are advanced information. If you want to take the time to read up on them and understand them better, then good for you! You will become more intimate and proficient with your Windows system than you ever thought possible. Go for it!

Test Your RAM – Windows Memory Diagnostic

Another Windows feature is the ability to test your RAM, or memory, and see how that’s all working. What you’re looking for is the Windows Memory Diagnostic tool. You can find that on your Start Menu > Administrative Tools > Windows Memory Diagnostic.

test pc hardware diagnostics

Once you click on that, you’ll be given the option to either restart the computer and test the memory now, or to test the memory on the next system restart. Unless you’re in a rush right now to find out, go ahead and choose the restart option.

test pc hardware diagnostics

Now, when you restart your computer you are going to see a text-based screen telling you that the memory test is being performed. There are things about the test that you can change, but it will run a Standard Test by default. That will be good enough for our purposes. Once the test is done, if there are errors, Windows Memory Diagnostic will try to figure out what memory module is causing the problem and tell you. That’s a good time to replace that bit of RAM.

Error messages will also be recorded in the system log in that you can access via the Event Viewer – another cool piece of Windows software you might not have known about. We have an article that delves into that a lot more by Saikat – it’s an oldie but a goodie and still applies – How To Solve Any Windows Problem with Event ID How To Solve Any Windows Problem with Event ID How To Solve Any Windows Problem with Event ID Read More .

What Else Can I Do To Check My Hardware?

Seriously? That’s not enough for you? Oh alright, I guess we do have a reputation of providing you with information about awesome freeware to uphold. Here’s a trio to get you started.

PC Wizard – CPUID

Great software, just be a little bit careful on the installation or you’re going to end up with the toolbar installed and have your homepage changed to Minor annoyances really, when you look at the value of the software package. It will tell you everything you’d ever want to know about your hardware, system configuration, resources, and help you set benchmarks for testing your hardware.

That way, you can have a historical view of how your hardware is performing and identify any decline over time.

Since I first started using CCleaner Optimize Your System To Run At Its Best With CCleaner Optimize Your System To Run At Its Best With CCleaner Over the last two years, CCleaner has changed quite a bit in terms of version numbers...up now to version 3.10 at the time of this writing.

Unobtrusive, instinctive, and they just plain work. Speccy, like PC Wizard, will tell you all about your hardware and then some. The Summary page gives you a great overview of where things are at, at a glance.

Sandra Lite – SiSoftware

SiSoftware is another long time player in the bench marking software world. I recall getting a trial version of this on a CD that came with a PC magazine back when I was in college. Yes that was last century. I was excited!! I have no idea what system I ran it on or what it told me, but I knew that it was industry standard software. There wasn’t a whole lot of freeware or even trials back in those days.

test pc hardware

Sandra is still an industry standard and you can get a Lite version of her for free. If you’re looking for more details on this version, it’s worth the time to read Matt’s article, Benchmark & Explore Your PC With SiSoft Sandra 2011 Lite Benchmark & Explore Your PC With SiSoft Sandra 2011 Lite Benchmark & Explore Your PC With SiSoft Sandra 2011 Lite Read More . All of the benchmarks are still in the newest version, whether it be your GPU, CPU, RAM, or HDD, Sandra will tell you where you are at.

The Take Away

What you should get from this article is that with just a little work and planning, you really should be able to avoid hardware failure surprises. Much like checking your tire pressure weekly, and changing the oil every 5000 km, computer maintenance by you should be habit and require the simplest of tools. You’ve already got them at your disposal, so why not make them part of your routine? You might save yourself a few bucks and you’ll definitely save yourself a LOT of heartaches.

Did you find this article useful? Learn a little something that you didn’t know? How about any other good tools to test PC hardware or monitor your hardware health? We’re always open and sharing – after all, we all in this together. Hit us up in the comments.

    Nice description of 'how to' with regards to upgrading RAM memory. I thought I was unlucky only having one slot so that I'd have to remove and discard the 4Gb card and replace with an 8Gb one. Having read about all the potential issues with the bios, maybe it wasn't so bad having only oneslot!

I ran the perfmon /report and it said all of my components were poor or very poor, desktop rating 0. What can cause something like this and how do I fix it?

    This article is supposed to be "How To Test Your PC For Failing Hardware", and the only useful part is using Windows Memory Diagnostic to test the memory's reliability.

    The rest of the article is useless because software benchmarks and performance monitoring do not indicate whether the hardware is failing or not.

    Just like asking someone to do a speed performance test on a car to see if the car's air conditioning system is leaking or not, is it logical?

    • Guy McDowell
      May 6, 2013 at 1:10 pm

      If I know that my HDD can spin up to 7200rpm, and I test it and it only spins up to 5000rpm, then yes, my air conditioning is working. Sorry, I mean my HDD might be in trouble.

    You forgot the reliability monitor - that can tell you if those crashes are really as bad as you may think they are - and how often issues are genuinely occurring. We tend to have a bad memory for them - and it gives you a more dispassionate view.

    in the past i used several program that detect failure in hardware. but my question is, is that info can be trustworthy like if i use scanhdd, it always show several spec that are over the limit and some time red marking. if that info really trustworthy or just an info of evaluate only? same with ramcheck. it allow me to refresh ram back to actual state. but i just dont seem any different when used it...

    • Guy McDowell
      April 27, 2013 at 6:17 pm

      It always requires a degree of interpretation. Part of the challenge is making sure you do your benchmarking when you get the computer so you have a benchmark to which you compare your later tests.

      Learning more about the hardware components themselves, you will also know how to visually inspect the hardware and interpret different sounds that it might make. For example, a hard disk drive that starts clicking audibly is going to fail very soon.

      • Mohammad Hamzani Salleh
        May 4, 2013 at 5:36 am

        owh thank for the info. and bye the way, if i used scanhdd nad the result show many aspesct and the most i see red is cyclic reduncy error. what it mean and do the hdd is nearly corrupted?

        • Guy McDowell
          May 6, 2013 at 1:28 pm

          CRC errors - or cyclical redundancy check errors - can be an indicator that there is something wrong with your HDD. It is almost always just an error caused by data being misread or written improperly to the HDD.

          If you are familiar with running Check Disk from the command line so that it runs on the next computer start, do that. It should fix all those CRC errors. I'll be doing an article on this very thing soon.

        Bundling an app to analyze your hardware for errors with crapware doesn't earn you decent respect. Judging by what people are saying, I'm sure it's a good software, but those who never heard of it might stay away because of that.

        • Guy McDowell
          April 30, 2013 at 9:44 pm

    • Mike B

      I use Belarc mostly as a utility to retrieve serial codes, but not for diagnostics of a pc. It can be used to see what service pack, updates, and other things are installed on the computer at the time and if any of those may or may not cause problems, but it is not necessarily a program for hardware diagnostics.

    • Guy McDowell
      April 27, 2013 at 6:19 pm
