There could be many reasons why you’ll need to troubleshoot your PC, properly, one actually and that’s because some thing isn’t working right. The system of troubleshooting is some thing you learn after running for a long time with computers. Often enough while there’s a trouble, nothing goes to explicitly tell you what’s causing the trouble and the way you may repair it. By taking logical steps and on foot thru the system of troubleshooting you have to be capable of resolving nearly any computer trouble, software or hardware associated. It involves identifying the trouble(s), locating the reason of that hassle, figuring out the solution, executing that solution, and testing and checking that way to see if it solves your hassle.

As an example let’s say sooner or later whilst the use of your PC the display screen suddenly turns all black and you can’t see anything. We discovered a problem now what would be the first step to take to repair it? First check to look if the screen is on and is receiving electricity, maximum video display units after they have power, however no connection or connection troubles with the computer will show a message that announces this monitor is working, but make certain you test your cables. So the next logical step to take might be to test the cable to make certain it’s far properly linked and secured to the VGA slot behind your laptop case and to make sure the reveal cable is plugged into the reveal.

Now, here’s in which you need to decide what will be the subsequent first-class route of movement to take. You could both swap out your reveal with any other screen which you understand is running to look if the trouble is the monitor itself and not anything else or you can try to see if the hassle is your pix card. If your replacement reveal works, true, then you understand your offender is a terrible display and you will most in all likelihood ought to get a brand new one, because video display units are risky and too luxurious service. If the substitute screen you used indicates up a black display screen as nicely, the subsequent component you would do is check to ensure the graphics card is nicely seated in the motherboard, if it’s far and the display is still now not displaying up, then change out the photographs card to peer in case your hassle is constant.

Generally, there are most effective so many steps you can take earlier than you resolve the trouble and the entirety is again in order. Make sure that before you begin testing and swapping out parts that the trouble wasn’t due to you converting a software program setting in Windows or a few ambiguous option inside the motherboard’s BIOS that reasons your problem.


The motherboard is the coronary heart of the PC, every part of the computer is based on the motherboard to feature correctly. It keeps the connection between every PC factor and ensures that things are running smoothly among them. Many signs and symptoms of motherboard failure are that the PC may not boot up, not reaching the POST take a look at, erratic device behavior, special mixtures of additives now not running. Because the entirety is attached to the motherboard sure parts may additionally or might not paintings effectively if the motherboard is faulty so make sure to check the ones parts earlier than thinking they are useless and getting new ones.

Be positive to do a visual inspection of the motherboard to make sure all cables are seated well, the lovers are spinning, and that the CMOS battery is in its right location. Also, test for any damaged or leaking capacitors, those can right away render a motherboard lifeless. Make sure that all of the jumpers are set efficiently as well, you must be capable of find jumper data in your motherboard’s manual, and in case you do not have the manual you should be capable of locating the guide on the Internet at the motherboard producer’s website.

Many of the problems because of a bad motherboard is likewise just like issues resulting from a faulty or loss of life energy supply, so make certain to check if the strength deliver is defective or swap it out for another to look in case your hassle is fixed. If you’ve got a spare motherboard you can attempt swapping out the motherboard to peer if that solves your trouble, if it’s the case then the motherboard is maximum in all likelihood defective. If you watched the motherboard is faulty and it’s far nevertheless in guarantee you ought to be capable of send it again to the producer for a brand new one with out a problem, now and again they may even pay for the shipping & handling if it is a large hassle that is happening with a certain line of motherboards. Make positive that whilst you open a motherboard you preserve all the packaging and the container, and if there are any stickers as a way to void the warranty if removed make sure you do NOT get rid of them, so that way it is less difficult to ship returned.


Power Supply

If you suspect your strength deliver is providing you with the hassle, make certain you test it out speedy, because energy supplies can make trouble for the relaxation of your device as nicely. Irregular voltages sent from the power supply can brief circuit and overheat your components, therefore, fry them and make them unusable. Some defective electricity materials have even caught on the hearth, however, if you’re fortunate it might simply smoke a little and start to odor. A few alerts that your energy deliver is horrific or is going horrific might be erratic and apparently random machine conduct like machine hangs and crashes, and burning smells along side smoke.

If you recently upgraded your machine or brought new tough drives, disk drives, a images card or something for that rely, be sure to test if your electricity supply is being overloaded with hardware. A precise manner to test is to use a strength supply calculator. One time when I upgraded my device with a new fancy PCI Express 16x Graphics card, nicely it turned into fancy again then, I had problems with the images card acting at the same time as in 3d games, it changed into all because of my electricity supply being unable supply it enough juice on the 12v rails so it done poorly and did not act as it have to have, I even swapped out the pics card for another one believing it was awful, after checking the producer’s forums it seemed like numerous people have been having problems with defective playing cards, so I figured mine should have been faulty too. After getting the brand new card it regarded like it performed better for a little bit longer, that could’ve just been some optimizations they did to circuit board. Seeing how they despatched me an upgraded model of the equal card, but it wasn’t until I checked my electricity supply wattages that I discovered the real culprit.

The first thing to do to diagnose your strength deliver is test the power supply connectors, ensure everything is plugged into the motherboard and the energy cable is plugged into the energy supply, you would not agree with how many human beings forget to plug their laptop. Many electricity substances also have an electrical switch on them so check to make sure that nobody accidentally or purposefully switched it off maybe for a prank. Check the fan to see if it’s miles spinning at the ideal speed and if it is dusty vacuum it out. Determine if the energy deliver cables are giving out the proper amount of voltage, in case you computer will assist you to boot you need to have the ability to check them within the BIOS menu to peer if the precise voltages are being given. Normal electricity components provide +three.3 volts DC, +five volts DC, -five volts DC, +12 volts DC, and -12 volts DC.


Faulty RAM could have many destructive outcomes in your device. Constant lockups, computer rebooting, reminiscence error message (duh), machine crashes, and now and again refusing in addition up are all symptoms of memory mistakes. Though, those are also signs of the motherboard, tough force, and power supply problems too. Luckily for you in case you assume your reminiscence is subject to inflicting a disruption for your machine there are programs which could check the memory for it is performance and to look if it’s far generating any errors.

After testing your reminiscence in case you acquire any mistakes you have to make sure that your memory is okay both by way of swapping it out and seeing the problems nonetheless arise or strive your memory in any other gadget. If the reminiscence passes the assessments then you continue to troubleshoot some thing else with proper religion that your memory is nice.

Hard Drive

The hard power is that closing safe to the whole thing critical in your computer. It maintains all your facts, documents and folders, song, movies, favourite web sites, and applications. With a horrific tough pressure there is no cause to have a laptop. In terms of fixing a laptop if the difficult drive isn’t always salvageable then most of the people do not even need to trouble with the rest, because their laptop is probably a bit of junk that has been passed down occasionally. Generally while a hard power is about to fail it’s generally years down the street from first acquiring the PC. So the following pleasant option instead of replacing the drive is to just buy a new PC, or construct a brand new one, due to the fact your old one certain might be no longer running as rapid because it used to.

Luckily earlier than your tough power kicks the bucket there is often a few warning symptoms:

  • Abnormally sluggish record transfers
  • Problems with booting, specifically when Windows is being loaded

If it does not show any of those tell-tale symptoms, but you’ve got a gut feeling that your hard drive is on the point of destruction you could try using many distinct pressure trying out utilities to be had at the net. The hard force manufacturer typically has at the least one qualified device that you could download from their website and run.

Other approaches to test the fitness of your tough force includes jogging the Windows Error Checking device by means of right-clicking on your difficult pressure in ‘My Computer’ then choosing ‘Properties’ and going to the ‘Tool’ and clicking on “Check Now”, or checking the SMART repute located to your motherboard’s BIOS. SMART stands for Self-Monitoring, Analysis and Reporting Technology. Most motherboards in recent times has this era. It have to be automatically enabled in your BIOS, if it’s now not then your tough force won’t get checked. What it does is on boot up it will carry out quick assessments for your hard power to make sure it is jogging efficiently and it’ll continue to reveal it for any mistakes or strange issues that can arise as long as the laptop is grew to become on.


Watching films, movies, playing video games, and looking at NSFW cloth are all terrific things we are able to do on our computers. Yet there may additionally come a day where you simply want to get to your PC and relax on your laptop room looking at all that NSFW fabric you have got bookmarked beneath the “Special Sites” class, however, you can not because your monitor won’t switch on. No, you don’t frump and punch holes within the partitions to look for an outlet for your rage. You troubleshoot it, and wish to god that your monitor isn’t damaged!

When diagnosing a display hassle, 1/2 the time it is commonly some thing very smooth, like a cable coming loose, or the display getting unplugged by accident; sadly the opposite half of the time it’s in all likelihood a trouble it’s associated with your display being old, or a problem it really is related to your pictures card instead. So you may diagnose both gadgets at the same time to look which solves your hassle.

First, test all your cables, I realize this is probably getting a bit vintage with the checking connections and everything, however so many PC troubles may be avoided if people simply remember that their laptop is not going to live the same manner they left it. A foot should kick out a cable, a dog or a cat that got too curious, or nearly something can render 1/2 your hardware vain.

After checking all your cables, make sure your screen has power, if it has electricity and indicates a message such as “This reveal is operating correctly please take a look at your cable” and shows bars of colour on the display, which means that your display isn’t getting a sign out of your computer. Try swapping out the display for any other one to see if it still says that message. If it does then which means the problem is maximum possibly some thing to do along with your pix card now not seated in the motherboard, or just isn’t always running well, you can want to strive to swap out every other pics card to peer if that solves your problem.

Generally, video display units don’t have that many diagnosable troubles. Either they paintings and that they work properly, or they don’t work and you have to update them. When running on a reveal you have to never open them, they aren’t intended to be serviced and incorporate excessively charged capacitors that keep lethal doses of power. We wouldn’t want to read approximately a laptop man within the obituaries now, would we?


Graphics Card

The superb images card, it is a great thing certainly. It makes all those quite HDR (High Dynamic Range) pics look just that suitable, it continues your video games strolling smoothly, and your films in HD. Yet this stuff may be pains while they may be just not working properly because if something is wrong there is not a strict hardware or software answer, you have got to investigate the present day scenario to see what’s up.

First and main in case you’re having any issues along with your pictures card, likely the first-rate aspect to try and do first is see if there an up to date driver for it on the producer’s website which could clear up the problem, or if there isn’t a replace attempt uninstalling your pictures drivers and reinstalling them this little motion can solve so many troubles.

If there is little jaggies or weird colourful mishaps known as artifacts acting for your display screen you can need to check the temperature of your graphics and ensure is getting sufficient cooling, and that the fan is running properly. If the cooling exams out k you may additionally want to check your electricity deliver ratings to look if it is giving enough juice to your portraits card. Nowadays most portraits playing cards want plenty of strength on the 12v rails, make sure your energy deliver can provide you with that electricity that the pics card wishes.

Sound Card

Some of the everyday problems human beings have with sound cards are both A) no sound or B) no sound. Sounds card usually aren’t very pricey so having to update one if the present day one isn’t operating is no large deal. However, in case you’re one of these audiophile types who count on a hundred% original recording first-class with your $300 sound card replacing one of these is as expected a lot more difficult to do.

Sound Card Troubleshooting

Check speaker cables make certain they are all linked and plugged into the right spot for your sound card. Also, test the speaker’s power cables. Make sure windows volume is turned up and the extent isn’t always muted, additionally make sure which you have all of the wave and playback volumes turned up and not muted. If you’ve got ‘Digital Output Only’ checked in your Advanced Controls for Playback Controls, strive unchecking it to see if that solves your non-sound hassle. I determined that if I actually have that checked my sound card won’t provide me any sound. Try reinstalling your sound card drivers, additionally attempt checking at the net at the producer’s website for any updated drivers that can be to be had. They growth your sound card’s compatibility together with your machine.
If the previous guidelines didn’t assist, then you may just have to replace your sound card, or at least switch it out for some other one to see if it is probably a hassle related to your sound card’s connection to the motherboard instead.

The processor is the actual wondering part of the mind of the PC. It does all of the calculations needed to make a laptop run and does them all in split 2d timing. It determines how rapid your PC normally runs, and most of the time is a bottle neck for systems which have had the entirety upgraded except the CPU. If your processor’s not operating, it’s not the end of the world, typically most processors that work successfully for some weeks, must paintings correctly for the rest of it’s lifespan, which varies from five-10 years or so. As long as you are now not overclocking the processor or letting it overheat too badly your processor ought to be satisfactory, and it could just be a BIOS setting it truly is tousled, or a jumper putting, however for kicks just test to make the processor is seated well and the heat sink is hooked up to the processor and the motherboard.

The warmness sink have to be connected tightly to the motherboard and now not have room to move approximately, you need to be capable of pick out up your motherboard by way of grabbing onto the warmth sink without any problems. Check your motherboard manual to ensure all of the jumpers are set efficaciously on your form of processor. Any jumpers set incorrectly can purpose the processor to no longer work, or function correctly or at it is most beneficial pace. Also take a look at the heat sink to peer if it’s miles cooling off the processor, if it is no longer doing a very good activity you could need to look at investing in a better one that gets the job achieved.
