Computer Hardware Troubleshooting

Here, in this article, we will manage the essential PC equipment investigating steps. We won’t manage the issues in the diverse equipment gadgets, but instead take up an issue, its reasonable justification, analysis, trailed by the investigating part.

There are different types of computer hardware, and of course, it would have been undoubtedly simple to deal with one hardware at a time and find out the problems associated with it. However, we know that when anything in our machine goes wrong, we are not completely aware of what exactly has happened, or rather, which part is causing the problem. So, I have decided that I will present to you the article in such a way that, we take up the problem first and then go for the troubleshooting, rather than taking a look at the hardware and the problem that it can cause.

Problem #1: Computer Does Not Start at All
If your computer does not get powered up at all, then the problem is very obvious. It has something to do with its power supply system.

Troubleshooting Procedure
This is one of the procedures that can either be very simple or can go way beyond your capability to solve. The solution may be as simple as replacing the power cable with a new one or as complicated as dealing with the SMPS of the machine. The SMPS is the Switched Mode Power Supply, the box at the upper left hand corner of your CPU, which powers up each and every component in your computer. If the problem lies with the SMPS, then solving it is not one of the DIY tasks that you would like to take up at home. It will need good technical expertise to solve the problem. Many times, the problem may have just one solution, that is, replacing the SMPS.

Problem #2: Computer Freezes or Shuts Down Suddenly
If you are facing the problem that your operating system stops responding suddenly or the computer shuts down by itself, then there may be some hardware related issue out here. Before I start off with the troubleshooting tips for this problem, I should tell you that most of the time, these are problems related to some software running in your system or because of some wrong driver installation. However, assuming that you have already checked out these problems and are sure that the problem is not related to the software, let’s start off with the hardware troubleshooting part.

Troubleshooting Procedure
Most of the time, this is a problem related to heat issues. If your processor gets heated up then there is a chance that your machine may shut down. The probable cause for this problem is that the fan in your CPU is not working properly. Here, I am assuming that you are using a desktop, as troubleshooting a laptop, would, of course require a lot of expertise. You can make out whether the fan is rotating properly, by simply observing it at the back of your CPU. There are also certain on screen system programs which can show whether your processor is over heated or not. If your fan is not rotating smoothly, then you have to get the connections to your fan checked. Another step that you can take is that you need to observe if the BIOS can properly load the fan when starting off the computer. However, if you find out that your fan is working properly, then you should take into consideration any new hardware that you had added to the system. Try removing that and check out if the machine restores back to working properly. There are chances that this hardware may be faulty. Replace it with a new one. Again, if you have not added any new hardware to your system in recent times, then the reason may be some part that is already there in your machine. Open your CPU cabinet and remove any extra RAM or extra hard disk that you are using. Check out if your computer works properly without that particular component. You can also try disconnecting your MODEM to check if the machine works properly.

Problem #3: Computer Boots Up Only from Floppy Drive
After starting up your system, if it demands you to insert a floppy disk to install the system, then probably there is some problem with the hard drive of the system.

Troubleshooting Procedure
Before going into the troubleshooting part and considering the hard disk to be corrupt, figure out in the BIOS settings, if your hard disk has been given the first priority for booting up. If it has not been given the first priority, then change the priority level and put your hard disk at the first priority level. If this does not help, then probably your hard disk is corrupt. In that case, if you have a recovery or backup system in your computer, then use it for recovering the data and the operating system. The other possible solution is that you need to reformat your hard disk.

The tips provided in this article are for the most common computer hardware problems that you may face. To have a deeper understanding on how to go ahead with the repair of even the most complicated problems, you need to get into the details of the working of that particular hardware device.
