Hardware and Software Maintenance Knowledge

Computer as one of the devices we use everyday, in the event of failure of one kind or another, give us the trouble can be imagined, especially rookie friends, in the event of failure to do nothing, the ongoing work of the hands can not be completed on time and fear broke his Scrapped hardware equipment, maintenance, and also bear the economic losses. In fact, so we do not have to worry, the computer most of the time when problems arise a number of small failures, learn some simple Aspire 5732Z Battery hardware and software maintenance knowledge and their own interests to control the computer much spleen. Here's a simple talk about daily life, to note what computer maintenance tips.
Computer hardware maintenance and software maintenance points to maintain two parts, hardware maintenance mainly refers to computer motherboards, graphics cards, processors, hard drives, monitors and other hardware equipment maintenance. And software maintenance, it means that after assembling the machine, the machine above the system software and application software maintenance.
First, hardware, computer hardware failures in very large and very complex, for example, we have seen the blank screen daily, boot no display phenomenon, the phenomenon of frequent crashes, IDE port, USB port failure, indicating that the color is not normal phenomenon, display jitter, Huaping phenomenon, the phenomenon of the hard disk can not read and write, the system can not start the phenomenon, the phenomenon of hard disk ..... too many bad sectors, these phenomena are actually generated on the hardware failures, as long as we carefully analyze, identify the causes for the Aspire 3680 Battery failure of computer illiterate users are likely to become common DIY expert, says the following about hardware failure, we need to follow the approach:
1. After the first peripheral hosts.

Failure on the peripheral easier to find and remove, we first error message on the system to check the mouse, keyboard, monitor and other external equipment and work. To consider the complexity of exclusion after the completion of the host part.
2. First, the power components.
Power users can easily be overlooked by the general shortage of power supply, the output current is not normal can easily lead to the production of a number of failures, often the user to motherboards, graphics cards, hard drives are checked over the reasons are still not found, does not know which is the power supply mischief.
3. To briefly after the complex.
Computer failure, the first from the start checking from the simple reason. Failure is often loose because the data lines, dust, such as caused by poor contact Aspire One Battery card. Done in a simple way to test the hardware and then consider whether the damage issue.
In troubleshooting, routine cases you can use to troubleshoot the following methods:
1. Plug substitution.
Plug replacement method is the oldest and most primitive method, and most have a direct effect of a method. Many hardware engineers are currently still use this method to exclude the computer the size of the fault. Plug replacement method is very simple, it is first of all based on computer problems, roughly where the problem is suspected, such as a computer monitor, graphics card, hard disk, keyboard ...., will be removed to install the object of suspicion to a good computer, if another computer does not work you can directly know the object out of the question. No problem to continue to doubt, replace, will eventually find the problem object.
2. Direct observation.
BIOS direct observation is based on an alarm of the instructions on the POST information to determine the hardware failure. Based on a variety of sounds and notes information to troubleshoot the failure, for example, to display the hard disk of a self-test problems, you can check the Presario r3000 Battery data on the hard disk and power cord for loose wire. Display problems, check the monitor and graphics card and the VGA port, erase the dust and see the interface without breakage and so on.
3. With special diagnostic software testing.
Diagnostic software is a specialized hardware troubleshooting tools that can help them quickly find out the causes. Such as the Norton Tools (Norton toolbox). The diagnostic software will not only be able to check the various components within the whole system (CPU, memory, motherboard, hard drive, etc.) health, but also check the stability of the whole system and the system the ability to work. If problems are found the report will give detailed information for us to find fault causes and troubleshooting.
4, minimized system checks.
The principle of minimum inspection system with plug replacement method is very similar. One by one with the smallest system that diagnosis. For example, install only the CPU, memory, graphics cards, motherboards. If the boot does not work, then plug the substitution of four components to troubleshoot with. If you can work, connect the hard disk. Draw a line HP Compaq 6510b Battery monitor. And so on, until you find a fault so far.
As for specific hardware failures and investigation methods, not a word to say that Dao Ming. If you want to be a DIY expert, you can go to the market to buy a special book or Internet search users in the message, the above described specific detail.
Software system is divided into two parts, software and application software, system software, users in the use of the process, such as the XP/2000 system, when used in the system for too long there will be many junk files generated. Ranging from space occupied by the system, while in the system hindered the daily operation of the system to make the system slow down or even not work. In the course of using the application software, many software applications installed, which appears in the system inexplicable phenomenon of the system of conflict, some normal functions are in the permanent of the abnormal phenomenon, these are inevitable.
In general, the software problems can be classified into the following categories:
1. The software is not compatible with the system caused the failure. Version of the software configuration and operation of the environment is not compatible, resulting in can not run, system crashes, some files had been altered and lost and so on.
2. Conflicting software failures. Two or more software programs operating environment, access to regional, work address and other conflicts, causing confusion in the system work, missing files and other failures.
3. Misoperation caused the failure. Misuse misuse and Pavilion DV9000 Battery software programs into the command to run misuse, the implementation of the order should not be used to select the operation should not be used to run some of the destructive process, incorrect or incompatible diagnostic procedures, disk operating procedures, performance test procedures, leaving the file is missing, the disk format and so on.
4. A computer failure caused by a virus. Computer viruses will greatly interfere with and influence computer use, can make the computer storage of data and information is destroyed, or all is lost, and will infect other computers. Most computer viruses can hide like a time bomb attack as standby.
5. Not the right system configuration caused the failure. System configuration fault is divided into three types, namely, the basic CMOS chip startup configuration, the system boot configuration commands to configure the system, if the configuration parameters and settings are not correct, or not set, the computer may not work and generate operating fault . Computer software failures can generally be restored, but in some cases, some software faults can be turned into a hardware failure.
In daily use, the authors summarize their daily maintenance of the knowledge of computer software, simple to talk about how to learn an ordinary consumer to protect their computer software, often used to make the new computer.
1. Institute of installed systems, learn to use the ghost.
In a laptop, a lot of things can not work, slow down, and as long as the Dell Inspiron 1520 Battery software failure, the most effective trick is to reinstall the system. As long as the system installed, the application software installed, is placed in front of a new computer. However, before the reinstall the system, first remember to backup computer system disk inside the personal information, and are ready installed in the system need to continue after the installation of application software. But you can not afford to install the system as a long time. Can learn to ghost, when installed on your computer, the use of ghost software backup once after system problems, as long it will take a few minutes with the ghost software to your computer with the same as the original.
2. Institute of virus.
QQ uploaded over the virus, which pass over the message the virus, it is easy to attack your computer, it does not work. Society is anti-virus software is a major thrust of routine maintenance. Under normal circumstances, even if there is a hardware firewall, but also installed such as Norton, Rising, and other anti-virus tools. And from time to time on the anti-virus software upgrades, maintain the capacity of the new virus alert, which would allow the safe operation of the computer in the network environment.
3. Learn to treat crash.
Met many of my friends hang directly on the power button to cold start, long way down the damage to the computer is great. In fact, for very many crashes, and sometimes lead to crashes system running conflict, more often or because the processor and HP EliteBook 8530p Adapter memory to run saturation has continued to give directions to their cause crashes, in which case the crash is not really crash, Sometimes we just feel can not switch to the new command, and the mouse on the screen or can be a normal move, this time not to rush to press the POWER button, you can wait a little. The principle is to treat crash: Death is a normal phenomenon, frequent crashes is an anomaly.
Of course, the computer hardware and software troubleshooting and maintenance there are many, the paper summarizes some commonly used to explore and maintenance of knowledge, the specific issues that require specific analysis, this paper does not specifically teach you how to check the specific computer appears failures, such as blank screen how to troubleshoot, how to re-system, I believe that these specific methods is not simply a few words can express accomplished. However, if you follow the general requirements described above do not panic experienced Dell Studio 1737 Adapter computer failure, I believe you will be the first rookie to a computer from Dr.
