Troubleshooting Basics
In this video from ITFreeTraining, I will look at some basic troubleshooting techniques. CompTIA has their own troubleshooting model, which I will look at in a later video. For this video, I will just give an introduction to basic troubleshooting techniques.

Basic IT Troubleshooting
0:15 To understand the basics of troubleshooting, let’s start with a joke which explains all the basic principles of IT troubleshooting. Consider that you have a car with a manager, an engineer and an IT technician all in the vehicle. The vehicle travels down a hill and the brakes fail. The vehicle travels at speed off the road and almost falls off a cliff.
Everyone gets out of the vehicle and are thankful that they are still alive after almost falling off the cliff. They all urgently need to get to a meeting in the city on the future of free training, so they need to get the car fixed and get on their way as soon as possible.
The manager says, “We need to have a series of meetings, work out a plan and a strategy. We next need to implement the strategy and then have further meetings to work out if the strategy was effective.”
The engineer says, “That is going to take too long and that never worked before. What needs to happen is that I need to get some tools and get under the car and fix the problem.”
The IT technician just laughs. “You’re both wrong. What we need to do is push the car back up the hill, roll the car back down the hill and see if it happens again.”
You can start to understand the basics of IT troubleshooting. One of the first questions asked is, can you replicate the problem? If you can’t, there is no problem to fix. Now you can understand why so many IT technicians will say, “have you tried turning it off and on again?” If you turn it off and on again and the problem goes away, there is nothing to solve.
Just for legal reasons, if the brakes on your car ever fail, please get them fixed ̶ don’t push the car up the hill and see if it happens again!
Let’s now have a look at what to do when turning the computer off and on again does not work.
Cause/Symptom/Consequence
2:02 There are many different ways to troubleshoot computer problems. One may work better in some cases; others may work better in other cases. Generally speaking, when a problem occurs, there is generally something that caused it.
In this example, we will consider that the hard disk is failing. The hard disk is sometimes not reading and writing data correctly. In computers, generally there is only one thing causing the problem and it is a matter of treating it like a logical problem to find out what it is. Find the cause, fix it or replace it and the problem goes away. In some cases, there will be multiple causes, but this is rare. For example, I once had a laser printer that was not working correctly. It had two faulty parts which needed to be replaced for it to start working again. I replaced one thinking this would fix it. When it did not, I removed the part and replaced the other part which again did not fix the problem. It took a while for me to work out that both parts were faulty. This is rare in computers, as generally there is only the one cause.

I fully agree. I work in school IT support and we regularly have users who claim they've "done everything" and it still doesn't work. Turns out they haven't restarted their laptop in months even if they said they did that or they didn't put paper in the printer's paper tray.

I fully agree. I work in school IT support and we regularly have users who claim they've "done everything" when in fact they did nothing at all. I ask them, "Can you please restart your laptop?" and they tell me they already did that. I check their device's uptime on PDQ, and it shows an uptime of 180+ days.... yeah. Closing your laptop's lid doesn't count as a restart.

@julia.carr1129 10 ай бұрын

"I JUST restart!" *Checks uptime..... it's at 32 days* "ok let's try restarting one more time" *issue is resolved

I thought that to troubleshoot a PC was easy but it looks like is more complex than I thought. I have no a deep knowledge with troubleshooting a PC but I consider that the troubleshoot depends on the PC

It sounds like Donald Rumsfeld famous quotations ! Rumsfeld stated: Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know.

Imma sum it up for the kids who were forced to watch this basically troubleshooting is having trouble with turning on something or troubles back starting something

@itfreetraining 10 ай бұрын

Troubleshooting is essentially the process of identifying and fixing problems or issues that prevent something from working correctly, whether it's turning on a device or getting it to start. This video goes into a lot more detail about how to troubleshoot when turning it on or off does not work. It's a valuable skill to have in the tech world.

Once I had random blue screens. But it wasn't any of the core components or hard drive. I didn't disassemble any parts for trial and error. After a while of scratching my head I started to suspect the wi-fi Bluetooth chip. Because there was another odd behaviour on the PC that looked unrelated to the blue screen. Randomly the PC froze for a few seconds and when it come back to life the WiFi was disconnected and I had a hard time bringing it on again. I replaced the WiFi module and the problem never returned. So look for clues. Sometimes troubleshooting is like detective work.

Nice work. Sometimes the problems can come up in the unusual places.

Hey dude my pc has trouble with restarting only like whenever I restart computer monitor displays black. How can I fix this please help :(

@itfreetraining 24 күн бұрын

So does the computer boot normally, but only has the problem when restarting.

@shrimpfryry6927 22 күн бұрын

@@itfreetraining yes I believe so it boots up completely fine but maybe a little slow and I do see a red led maybe dram light on the mobo whenever it boots. The light disappears after it boots but when I restart it displays black and that red dram light just stays on forever

I assume your talking about Close Captions message disappearing. Back when we started releasing these videos we have people asking for captions even though they were already on the video. So we added Close Captions icon at the start of video to make sure people were aware captions on the video.

The video is about basic troubleshooting and general strategies. Is there something is particular you are trying to troubleshoot? We have many videos on different topics.
