Influence of switching computer times on computer host life

What are the effects of switching computer mainframe on computer life? when the switch machine will cause a certain impact on the host, in particular, the damage to the hard disk, it can not be done frequently to open the machine action, switch machine should be a moment interval, there is information that a minute for the good, illegal shutdown, such as power cut damage is even greater, preferably for the computer with uninterruptible power supply ups.

And a long time on the operation will make the electronic components in the machine, especially the monitor long-term at high temperature work, accelerated aging, as well as the accumulation of dust, will also have a certain impact on computer life. To sum up, I think the frequent opening of the machine than the long running on the computer's life more impact, generally shut down at least 3~6 times per week for good. From the point of view of household saving, more than 1 hours without the computer to turn off the monitor, more than 4 hours without the computer to shut down the host.

How to maintain a good computer and to maximize the service life, is our vast number of computer enthusiasts are very concerned about the topic.

First, the environment

The influence of environment on computer life can not be neglected. The ideal operating temperature of the computer should be in 10℃~35℃, too high or too low will affect the life of the computer accessories, when conditions permit, the computer room must be installed air-conditioning, relative humidity should be 30%~80%, too high will affect the CPU, graphics and other accessories performance play, and even caused some parts of the short circuit. For example: In the south the weather is more humid, it is best to use the computer every day or to power the computer for some time. Some people think that the use of computer less or short time, can prolong the life of the computer, this is one-sided, vague point of view; on the contrary, the computer for a long time, due to damp or dust, sweat and other reasons, will cause damage to computer accessories. Of course, if the weather humidity to a certain extent, such as: monitor or chassis surface water vapor, at this time can not give power to the machine, lest cause short-circuit and other unnecessary losses. Humidity is too low easy to produce static electricity, the same use of accessories is unfavorable. In addition, the dust content in the air has a greater impact on the computer. The dust is too big, will corrode each part, the chip circuit board for a long while, the content is too small, will produce the electrostatic reaction. Therefore, the computer room should have a dehumidifier and vacuum cleaner.

The computer also has a demand for power. The normal range of alternating current should be in 220v±10%, the frequency range is 50hz±5%, and have good grounding system. When the condition allows, use UPS to protect the computer, so that the computer can continue to run for some time when the mains is interrupted.

Second, the use of habits

Good personal habits also have a big impact on computers. Please perform the open and shutdown sequence correctly. Boot sequence is: first peripherals (such as: printers, scanners, UPS power, modem, etc.), the monitor power supply is not connected with the host power, but also to turn on the monitor power supply, and then open the host; The shutdown sequence is the opposite: first off the host, and then off the peripherals. The reason is that as far as possible to reduce the damage to the host, because when the host power, shut off the peripherals of the moment, will produce a strong impact on the main current. Shutdown after a period of time, can not frequently open, shutdown, because this impact on the various accessories is very large, especially for the hard disk damage more serious. A general shutdown should be at least 10 seconds from the next boot time. Special attention should be paid to when the computer is working, should avoid the shutdown operation. For example: When the computer is reading and writing data suddenly shut down, it is likely to damage the drive (hard drive, floppy drive, etc.), and not to move the machine when the machine is working properly. When shutting down, you should be careful to quit the Windows 95/98 operating system, close all programs, and then exit in the normal shutdown order, or you may damage the application. Of course, even if the machine is not working, you should try to avoid moving the computer, because too much vibration will be hard disk, motherboard and other accessories caused damage.

Third, hardware failure

Under normal circumstances, a newly installed computer failure is more likely, the machine runs for a period of time, the failure rate is relatively lower. For hardware failure, we only understand the characteristics of various accessories and common troubleshooting methods, you can eliminate each fault.

1. Bad contact trouble is generally reflected in a variety of boards, cards, memory, CPU and other contact with the motherboard, or power lines, data lines, audio lines, such as poor connectivity. A variety of interface cards, memory and motherboard contact with the bad phenomenon is more common, usually as long as the replacement of the corresponding slot position or with an eraser rub gold fingers, you can troubleshoot.

2. The settings of the parameter CMOS parameters are not set up with the main hard disk, floppy drive, memory type, and password, machine boot sequence, virus warning switch and so on. The system prompts for an error warning because the parameters are not set or improperly set.

3. Hardware itself failure hardware failure, in addition to its own quality, but also may be due to heavy load or other causes, such as power shortage or CPU overclocking use, etc., may cause computer failure.

Four, software failure

Software failures are usually caused by improper installation of hardware drivers.

1. The failure to install a driver or conflict between drivers will result in the discovery of some tags in the resource Manager under the Windows 95/98 operating system, where "?" Indicates an unknown device, usually the device is not installed correctly; "!" Indicates that there is a conflict between the devices, and "X" indicates that the installed device driver is incorrect.

2. Virus prevention virus to computer harm is well-known, light affects machine speed, heavy damage file or cause panic. To facilitate the maintenance and maintenance of your computer at any time, you must prepare the necessary tools such as a clean DOS boot disk or Windows 98 boot disk, as well as KV300 kill virus, Norton tool software, etc. to cope with system infection or when the hard disk does not start. In addition, the driver should be prepared for various accessories, such as optical drive, sound card, display card, modem, etc.
