Q: What are the common computer threats and what are the hazards?
Trojan Horse is the most common computer threat, is the intrusion of user computers, opportunistic steal account password malicious program. Usually, the Trojan will automatically run, in the user login game account or other (such as net silver, chat) a
Comments: When maintaining and using computers, network administrators often encounter various password loss problems. Here, we have prepared some methods to crack the passwords for the majority of network administrators, but I hope you will not do anything bad. The boot password is the first one we need to deal with, so we should start with the CMOS password cracking. Although there are different types of CMOS, their encryption methods are basically the same.
Whether you're looking for an amazing media experience or looking for a mobile office, or just a reliable daily home computer operation, an ideal laptop can always fulfill those aspirations. The trouble, though, is choosing laptops because there are so many products to choose from.
This purchase guide helps you to make an orderly selection among the many choices. Here, we will introduce some basic common s
boards that do not support the pcw.memory stick, you can try to reduce the memory read speed in the CMOS settings to see if the problem can be solved. If not, you only need to replace the DDR2 memory and DDR3 memory.5. Random crashThis type of fault is generally caused by the use of several different chips of memory, because the speed of each memory is different, resulting in a time difference, resulting in a crash, this can be solved in the CMOS settings to reduce the memory speed, otherwise,

One-click restoration is to allow the system to return to the status of the previously backed up system. Generally, the operation takes more than one minute. This simple method has become a common method for many computers to "cainiao" to handle system problems.
"One-click restoration" is equivalent to Resetting the system andHardware will not cause harm, so you can use it with confidence. It is worth noting that the "one-click restoration" function
Computer Board common problems and coping strategies Common failure One: no display Computer boot No show, first we have to check is the BIOS. Important hardware data is stored in the BIOS of the motherboard. At the same time the BIOS is also a more vulnerable part of the motherboard, very vulnerable to damage, onc
Solutions to nine common problems with computer memory
1. Failed to boot normally
Solution: there are three main ways to solve this problem: first, change the memory location, which is the simplest and most commonly used method, generally, the old low-speed memory is inserted in the front position. Second, when the system is able to boot, enter the BIOS settings and set the memory-related settings according
XP system computer Hardware common problem analysis is as follows:
1: The computer's motherboard capacitor damage to our graphics card is not normal use, the solution is that we directly use the capacitor on the motherboard to replace the nominal value can solve the problem.
2: The computer power switch can not be used normally, the Start button is not open aft
The video card and display constitute a computer display subsystem. Under normal circumstances, the failure rate of the video card is not high, but as the number of applications increases and the performance increases rapidly, the failure rate of the video card increases rapidly. A display is a special part in a computer. It is relatively independent from the host. As a strong electrical device, we cannot m
