Every computer consists of hardware components and software. Everyone wants to have the best components for his computer. This is very important because by having good hardware components within our computer means having a good computer. Unfortunately, soon or later every user will get encountered with some problems within the functions of his computer. It is very important for the user to be well informed so as to be able to overcome these problems when they occur. Among the many errors that can occur on a computer screen and that are caused by different computer hardware components there are some that the user can overcome himself by following certain simple troubleshooting steps available for all of us nowadays. These are referred to as common problems about computer hardware.

There are many different types of computer hardware components: different types of printers, different types of network adapters, different types of monitors, different types of motherboards, and others. In addition, the users have the opportunity to choose from a great amount of offers present on the market nowadays the one that best suits their needs and choices.

One of the common problems about computer hardware is the one that might appear when a new hardware is being installed on a computer. What is very important for the users to know before starting to install a new hardware within their computers is that they must pay attention to the manufacturer's instructions, even if it seems easy for them to do this task or they have done it before. The steps must be followed exactly so that no error might occur at the end of the installation. Also, it is important to know that even if it seems logical to first connect the hardware to the computer and then install the necessary software it seems like there are some situations in which it is required to firstly install the software and then the hardware. In this respect, the instructions must be read before doing any task and before turning the computer on. In this way, other common problems about computer hardware can be simply avoided.

Among these common problems about computer hardware is logically included the case in which the user does not succeed in installing the device correctly because of not having been attentive to the instructions. Fortunately, this type of installation problem can be easily solved, but it is better if it does not occur. But, just in case, it is better for the users to know that in the case in which the installation problem appears they have to disconnect the hardware and to remove the software. Afterwards, by following the instructions the user can install the hardware again. Usually, after installing the hardware it is necessary for the user to restart their computers before doing something else on their computers.

There are some steps that the users can follow in order to discover some common problems about computer hardware. Sometimes, it is possible for a user to identify that the cause of the displayed error is due to the fact that a certain device is broken. In this case, the only possibility that the user has is to replace that certain device, as it cannot be repaired so that it might work properly again. And even if it could be repaired it surely would not be a good idea because it would not last too much. Replacing these devices is what the users encountering this type of problem must do.

Another possible common problem about computer hardware is considered to be a faulty port. In this case, it is advisable for the users to connect their computers to another port available for them. After the user has done this, he can proceed with the reinstallation of the hardware. After this has been done the user can conclude the fact that the problem had been caused by the port having been used and not by his hardware. It is very important for the user to get at the stage in which he can certainly say which device is causing the problems and which is not. This is because, in this way, he will know what step to follow next.

Another common problem about computer hardware that a user might encounter can be related with the computer configuration. In this case, it is recommended that the user might connect his hardware to another computer, if he has the possibility. This is an important step for the user to try and follow because it is the only fast method in which he can test to see whether the problem of his computer is caused by the hardware or by the computer configuration. The user will know after he has connected his hardware to another computer. If that computer works properly, this means that the hardware works properly and the cause of the errors displayed on his computer caused by its configuration. This is not the only chance. The user could as well ask for further assistance from the manufacturer of the hardware or from other specialized persons in dealing with common problems about computer hardware.

Nowadays, there are many common problems about computer hardware that users can encounter when having and working with a computer. No matter how good hardware can be, sooner or later certain problems related to it might occur. This is why it is very important for the users to become aware of the necessity to know how to overcome certain problems when they are faced with them. Some of the errors that can appear within the functions of a computer can be solved easily by following certain simple steps and these are known as common problems about computer hardware. It is not the case for all the problems that a user can encounter when using a computer. For more complex problems the user might need further assistance from a certain manufacturer or from specialists who might deal easier and better with that certain problem.

It is important for the user to be very well informed before trying to repair something or replace a certain computer hardware component. It is not advisable for a user to do any of these tasks if he does not know exactly what and how to do. This is because if certain tasks are not done well, other problems within the computer are likely to appear.

Every computer includes hardware and software components. Both of these two types of components are very important for the way in which the computer functions as a system. The users are more familiar nowadays of the way in which they could overcome certain computer hardware problems than they used to be. This is because they can access all sorts of  information that can help them understand which steps to take so as to be able to work properly with their computers and overcome certain problems that might appear.

Nowadays, there are many ways of testing computer hardware problems: cable testers, software, routines, POST cards, error diagnostic types of methods and others. Hardware components are those parts of the computer that can be seen and touched within a PC. In comparison with the software the users change hardware components much more often. Among the most important computer hardware components are the hard disk, the motherboard, the random access memory, the CD-Rom, the printer and other types of peripheral devices.

There are many types of computer hardware problems. The errors which usually occur before the initial beep usually show that some computer hardware problems exist within the computer system. In the case in which the computer produces an error the beep code is likely to appear. This beep is usually the sign that we have a possible problem within the random access memory, which might need to be changed.

There are also some computer hardware problems which might appear when a new hardware is being installed and the system uses it for the first time. This problem is usually caused by the mismatches between the CMOS memory and important information about the necessary configuration of the component. It is also possible for the new hardware to present some sorts of errors in the case in which the computer hardware problems continue to appear after all the necessary steps have been followed in installing the new hardware. There are three such types of problems encountered by the users nowadays: boot problems, operational types of problems and configurations problems.

The general computer hardware problems that occur between the beeps and the initialization of the computer a system are known to be: hardware failure, general failure, bad command interpreter, disk error, non system disk, bad file allocation of table, corruptive operating system files, missing operating system files, corrupted boot files, missing boot files and others. In general, the technicians do not advise users to repair computer hardware components but to replace them as they are not considered to be very expensive.  This is because the repair of a certain hardware component can be sometimes more expensive than the replacement itself. There are some important types of testers that users can access nowadays to diagnose their computer hardware problems. Among these there have become very familiar the cable tester, the POST card, the multi meter and the software type of diagnostic disk.

When discussing about the software diagnostics disk it is very important for the users to know that these testers are able to check the computer system and identify certain types of problems by running some kinds of tests on the system hardware. The nature of the problem can also be established by these types of testers. In general, the most well known software testers identify problems such as the computer' memory, the system processor, the hard disk, the monitor, the keyboard, the central processing unit and others. It is very important for the users to try and eliminate certain possibilities among the devices that might be causing the problems before evaluating the ones that are more likely to be the cause of that certain problem. When the software tester device identifies the problem, it is advisable for the user to replace that component rather than repair it.

The multimeter type of tester is a very important tool in troubleshooting computer hardware problems. This type of tester and other can be found both in analog and digital form. These types of devices are usually used to measure the values of the voltages within the system. They are also used to check the transistors, the capacitors, the diodes and others. A POST card is known to be a device that is usually plugged within the expansion types of cards and it analyses the way in which the system operates as it is being booted up. These types of testers are usually used by technicians when the system seems to be dead. In addition, this type of tester is also used in the case in which the computer is not able to read floppy disks or hard disks. There are two main types of errors reported by this type of tester, a non-fatal type of error, and a fatal one. In establishing the type of error displayed it is very important for the user to pay attention to the timing of the error message and also to the beep code. These two factors influence very much the type of error that the user should consider.

Another type of tester for computer hardware problems is considered to be the cable type of testers. These testers usually deal with problems such as bad cabling and RJ-45 type of connectors. In this respect, there have been created several types of devices for testing network communication cabling, important for the way in which the computer operates. There are different types of tests that the cable testers are supposed to be able to perform on computer cables. Among the most common types of problems encountered by users in this respect are the broken wires, crossed-over wires or improperly impairs cable connections.

Nowadays, it is very important for the users to have at least some basic information about their computer hardware components and the computer hardware problems that might occur within their computers. By being informed they will know how to overcome these problems when they occur and they will be able to continue working with their computers. Computer hardware problems are various and numerous. The hardware components that usually present problems are more advisable to be changed than repaired.

Nowadays, there are some users interested in knowing the historical development of computer hardware. The first use of the word "computer" has been considered to be in 1613 and has been attributed to a person carrying about all sorts of calculations and computations. Later on, this meaning of the term computer was kept until the 20^th century. By the end of the 19^th century another meaning of this word began to be used and this meaning is nowadays very familiar among people: a machine dealing with carrying out all sorts of computations.

Every computer is known nowadays as being made up of hardware components and software. The hardware is considered the most important part within the computer. It has been considered the fact that all sorts of devices shave been using for many years in order to help computation. A computer is usually defined as a machine dealing with the manipulation of data by using certain instructions. The first electronic types of computers are considered to have been developed between 1940 and 1945. They were very big in size which led to very big power consumptions. Some of them have even been considered to be the size of large rooms and with a power consumption equal with that of ten modern computers used nowadays.

The historical development of computer hardware has been considered interesting to be studied by some users. Certainly, it is well known that modern computers that are used nowadays are much more capable than the old ones, and this is normal as the old one have very much been improved so as to be transformed into what we call nowadays modern technology. The new ones have included integrated circuits and occupy very little in comparison with the space that the old ones used to occupy. There are nowadays very small, simple computers present among the offers on the market, so small that some can even fit into a wristwatch, being powered by using watch batteries.

In the historical development of computer hardware the main difference between computers and calculators has been considered to be the fact that computers can store and execute instructions and programs. When discussing about modern computer monitors it is important to talk about two different technologies: automatic calculation and programmability. It has not really been possible to identify which of these two different technologies is the earliest one.

In the historical development of computer hardware the father of modern computer science is considered to be Alan Turing. He was considered to be one of the most influential persons of the 20^th century. George Stibitz is considered the father of the modern digital type of computer. Other important computing devices constructed in the 1930s and 1940 s are the electromechanical Z machines, the non-programmable Atanossoff- Berry computer, the British colossus computers, and others.

Some researchers have considered five generations of computers in the historical development of computer hardware. The first generation has been considered to include the types of computers used between 1951 and 1958. They were much less advantageous than the ones that we are using nowadays. This is because they used vacuum tubes and were consuming a lot of electricity. They also generated too much heat in comparison with the modern ones and were not too long-lasting. Their memory capacity was very weak, of almost 2 Kb and their design was kind of awkward when we see our modern computers nowadays.  The second period included the computers used between 1959 and 1963. They are already using less electricity than the ones from the previous period. Also, the heat generated by these computers was much lower than in the previous case. The memory was enlarges, being of 32 Kb and they used magnetic cores for their internal storage.

The third generation of computers in the historical development of computer hardware was the one represented by the computers used between 1964 and 1979. They had integrated circuits which are nowadays considered very simple. The maximum memory storage was of2 Mb. A very good improvement in these computers has been considered the possibility for some programs to run at once, which was not considered possible in the computers included in the previous two generations. The fourth generations, the computers used between 1980 and2005 were already much better than the all of the old ones. They already included complex circuits which had a very large capacity compared to the ones presented in the past. The memory storage was totally improved being able to reach several GB already, by using memory cards. The computers in the fourth generation included all sorts of new features such as printers, scanners, new monitors and text converters. In this period, the specialists have established the foundation of the computers that we nowadays consider modern.

The fifth generation of computers considered within the historical development of computer hardware includes the computers used since 2006 and until now. These computers are considered to be able to process information much faster. They are also considered to be biocomputers.

The first computers were considered to be all hardware. They only contained electronic and electromechanical types of elements: wiring, switches, vacuum tubes and others. Nowadays, computers consist of both hardware and software. They are considered much more improved than the old ones. There have been many types of computers since the first type of computer has been used. They have changed a lot because the specialists are always trying to improve them and to find new special accessories and features to include in them so as to make them work much better and to be a great aid for the users. The historical development of computer hardware has been considered very interesting to analyze by many users who have been curious to know how the old computers used to look, what kind of computer hardware components they consisted of and also, which are the main improvements that have been made to these computers in order to have nowadays modern PCs. There are important stages that have to be analyzed and considered in order to establish as best as possible the historical development of computer hardware.
