best computer maintenance programs

Computer motherboard maintenance of the main should be to do is dust and moisture, CPU, memory, display card and other important components are inserted in the motherboard, if too much dust, it is possible to make the main board and the components of poor contact, resulting in such an unknown fault, to your work and entertainment brought great trouble; If the environment is too humid, the motherboard is pro

First, to pay attention to dust, moisture and ventilation; Second, to regularly defragment the disk (according to the amount of disk writes, but not appropriate too frequent); Third, when the computer is open (especially when reading and writing disk), do not easily move the host, easy to damage the disk; Four, after the use of more than a year, you should periodically check the CPU and power supply fans of the complete and stability. Five, to reg

the shutdown application and then cut off the power of the time will often occur, we may be in many forums and newspaper questions and answers column, all see the question " Why the soft shutdown when the "problem"-at this time the hard drive reset action is probably not completed, if the user uses forcibly cut off the power of the practice, hard disk physical damage is a great possibility. * Correct approach: If the soft shutdown when the crash, should be pressed reset key, so that the system

For friends who use the Windows XP operating system, when the operating system crashes or when there are some inexplicable errors in use, it is generally used to reload the system or use Ghost for system recovery and other methods. However, the use of these methods are flawed, such as reinstalling the system, the original system settings and software must be reinstalled, very cumbersome. In fact, every system error has a way to repair, and the Windows XP operating system with the system repair f

paid to the computer peripheral other equipment and geomagnetic interference to the computer. Iv. Points of judgement/order 1, before the maintenance of the preparation The latest version of the driver for the corresponding display card 2. Environmental inspection 1) mains check: A. Whether the mains voltage is in 220v±10%, 50Hz or 60Hz, and whether the ma

plug-in, after changing the PDF plugin, the problem is still unresolved, that is mostly something in the interception,, so I first shut down the firewall, but still no,, finally I put 360 security guard to uninstall, restart the computer, Then remove the remaining files from the 360 Security defender installation directory, retry, solve the problem! This article is from "I am again to install B" blog, please be sure to keep this source http://flaming

This article from six to talk about the major parts of the notebook computer maintenance skills. (i) Use of lithium batteries 1, usually in the occasion of alternating current to use AC adapter power supply; 2, every one months at least the lithium battery after a single (full discharge) recharge, 3, the new battery should be completed more than two times complete discharge and charge; 4, in the Control P

, the software is slow to open, because the computer's internal virtual memory space is too small, because the operation of unrelated files and program fragments too much. So whether the system garbage or registry garbage needs to be regularly cleaned up, computer-independent programs run smaller, the less easy to the current program to interfere with the operation of the obstruction.

reading disk or other vibration on the hardware adversely affected. 8. When the display after the use of the dirt is not easy to remove, can be contaminated parts with the mouth ha heat, followed by the use of flannel to wipe clean, the effect is obvious. 9. The internal clutter of the data line, the power cord can be tied up with wire or rubber band, this not only gives people a neat feeling, but also convenient host cooling. 20. Do not put the phone on the monitor or the speaker side, beca

"Substitution" is a way to find or troubleshoot a failure by replacing a part that may be faulty or without fault, but not working properly. The "control method" is to compare the faulty computer or component with a computer or component that does not have a fault, to find out the method of troubleshooting. Both of these methods are useful, and they are used in many troubleshooting of the

One, the hum of winter A few days ago really very cold, I do not know whether you found that your usual quiet computer is now turned on when the sound of a bad hum, but after a while, this voice will gradually disappear. What's the reason? In fact, that's probably the trouble with your CPU fan. When the temperature is too low, the fan lubricating oil some solidification, and the combination of dust and oil, make the fan rotating difficult, so that the

digital signal processor is used to process the data signal transmitted by the forward signal processor, decode the signal, or receive the data signal transmitted by the computer, and encode the signal. 8. Motor Drive Chip The motor drive chip is used to drive the hard drive spindle motor and the voice coil motor. Now the hard drive because of the speed quickly, easy to cause the chip calorific value and damage. According to statistics, about 70% o

When you are working on a notebook computer, if you read a file or run a software, it often goes wrong, the system starts slowly, or it takes a long time to operate successfully. During the hard drive constantly read the disk and make a harsh noise: or on the boot system can not boot through the hard drive, the CD can be turned to the hard disk after the boot letter. But can not enter, use SYS command conduction system also cannot succeed. Severe when

Chapter I basic principles and methods of computer maintenance The principles and methods described here are the basis of the second part of the classification judgment, which needs to be conscientiously complied with. §1.1 the basic principles of computer maintenance should be followed: First, the

Thinking logic of computer programs (27), thinking 27 In this section, we will continue to discuss the packaging class, mainly the Integer class. Next we will introduce the Character class. Long is similar to Integer, so we will not discuss it separately. Other classes are basically introduced and will not be described again. What else do I need to introduce to a simple Integer? It has some binary operation

Thinking logic of computer programs (26) and thinking 26 Packaging Java has eight basic types, each of which has a corresponding packaging class. What is the packaging class? It is a class that contains an instance variable and stores the value of the corresponding basic type. This class generally has some static methods, static variables, and instance methods to facilitate data operations. In Java, the bas

Many people know that to ensure the normal operation of the computer, it is necessary to regularly give the computer "maintenance." But as long as there are no particularly serious problems, people often forget to do it. To solve this problem is not difficult, the computer butler's "

Thinking logic of computer programs (94) and thinking 94 The previous two sections discussed functional data processing in Java 8, which is an enhancement to the container class introduced in sections 38 to 55, it can combine multiple operations on the set data in a pipeline. This section continues to discuss the new features of Java 8, mainly a new class CompletableFuture, which is an enhancement to concur
