Analysis of classic faults in Internet cafes

1. Run the legendary high-definition version of the game to crash

Fault performance: machine configuration: the CPU is AMD 2500 +, the motherboard is the elite KT600, the video card is a miscellaneous card 5200, and the common power supply. After installing the legendary high-definition edition, the machine crashes after a period of time. This machine runs normally while using the Legendary World's low image quality assurance. Later, tests showed that the machine would crash as long as it runs a 3D game. When running a non-3D game, everything works. If you suspect that the video card is faulty, you can test it at the dealer when you take the video card to the dealer. Everything is normal. Go to the BIOS settings of the computer, change the AGP video card from 4X to 2X, and run the legendary high-definition edition again. After the other motherboard is changed, the fault still cannot be ruled out.

Fault resolution: due to the high CPU power of the ADM series, when using the AMD series CPU, be sure to select a pass-through power supply. We can replace the power of the machine with a larger power supply to solve the problem. The fault is caused by insufficient power supply of the AGP slot.

Fault comments: the video card crashes when running 3D games. There are mainly the following reasons: the power supply of the AGP slot is insufficient, and the running speed of The AGP video card does not match the BIOS settings. The fault is caused by insufficient power output, resulting in insufficient power supply for the AGP slot and the device crashes. When we use AMD series CPU machines, we must buy a brand-name power supply to ensure the normal operation of the machine. Nowadays, hardware vendors often exaggerate the actual power of power supply to improve the selling point of power supply, which leads to misunderstandings during purchase. Some inferior power supplies have a nominal output power of 400 W, and the actual output power is only 180 W. Therefore, when purchasing a machine, do not ignore the power supply which is considered unimportant.

2. garbled characters are displayed in some software.

Fault performance: Recently, my machine often encountered such a strange phenomenon: the menus on some software interfaces were garbled, but there was no garbled menu during previous use. Why? This error does not occur if the operating system is Windows XP and the computer cloned from the same master disk is used. Scan the hardware using anti-virus software and no virus is found.

Fault resolution: Garbled menus are generally caused by changes to the "region and language" configuration of Windows XP. Solution: Open "region and language" in the control panel, select "Chinese (China)" in the "region options" tab customization, and select "China" in the "location" item "; on the "advanced" tab of "region and language", select "Chinese" for the language of the non-Unicode program. Then, the problem can be solved.

Fault comments: in our daily use, we seldom ignore some minor options set by the system. The emergence of this fault makes us not to ignore any minor problems in our technical learning.

3. The machine can access QQ, but cannot open the webpage

Fault description: The Internet cafe client operating system is Windows XP. The default Anti-Virus Software Enterprise Edition is used, and the proxy Server is the Windows 2000 Server operating system. After the Skynet firewall is installed on the proxy server, all the following clients can only access QQ, but cannot open the webpage. Check the DNS and gateway address settings of the client. Everything is normal.

Fault resolution: This fault is caused by the high security level of the firewall. After installing the firewall software on the proxy server, do not set the security level of the firewall too high; otherwise, the normal data packets will be filtered.

4. Internet cafes cannot access the Internet, and network cards and network cables are not faulty.

Fault description: The Internet cafe client is a Windows 98 operating system. Due to virus attacks, the system is cloned again. After cloning, a machine is found to be unable to access the Internet. Check the network neighbor settings and find that the NIC driver is installed. The IP address, gateway address, and DNS server address are set properly. When you Ping an intranet Gateway by using the Ping command, the connection fails. Put the network cable on another machine. Everything is normal. After the NIC is replaced, no fault is found.

Troubleshooting: For the cloned Windows 98 operating system, this problem often occurs. Some hardware drivers are not installed, but are displayed in the system. The same is true for the above faults. You can directly Delete the NIC Driver and reinstall the NIC Driver. To clone the Windows 98 system without errors, you must install the NIC on the same PCI slot. For example, all NICs are installed on the third PCI slot of the motherboard, in this way, no error will occur after the system is cloned.

Fault comment: Windows 98 operating system does not support the hardware plug-and-play function very well. Therefore, After cloning Windows 98 system, the driver may be installed falsely. Therefore, we recommend that you reinstall the hardware driver in the cloned Windows 98 operating system.

5. Sound Card burst

Fault performance: the Internet cafe client uses the Intel 845G motherboard, and the sound card is the integrated AC '97. However, it has recently been found that sound cards often appear without reason. It is suspected that the headset hardware is damaged, but after the headset is changed to another machine, it works normally. After the sound card driver version is changed, the sound is still cracked. After replacing the motherboard With another machine for testing, the sound card works properly.

Fault Analysis: Sound Card burst, generally caused by poor contact between the headset and the sound card interface, poor contact between the headset line, and sound card damage. In addition, if the computer chassis is too static, it will also cause a sound card burst fault. After a good grounding method is provided for the chassis, the sound card burst phenomenon is eliminated.

Fault comment: according to the manufacturer's production standards, our computer power cord should be composed of three wires, and the computer manufacturer will omit a wire responsible for the ground to save production costs. We can split a power cord and find that there is no wire in charge of the ground line. There is only one plug on it. Therefore, in daily use of our computer, we need to do a set of good grounding measures. The computer chassis is prone to damage to computer hardware after a large amount of static electricity is collected.

Summary:

Although the faults that have occurred in this period seem to be some inconspicuous minor faults, these minor problems cannot be solved without solid basic computer knowledge. Therefore, in our daily study, we should not just look at the long story, but ignore the basic knowledge of computers.
