Internet caf hardware common those failures 50

There are many problems, and in general, you can solve them if you find a good mechanic. The problem is nothing more than hardware and software.

1. More money on the hardware does not necessarily mean that a good machine can be installed, and the problem of compatibility must be solvedThe system must be done well, and the system is very important.

3. Pay attention to safety, and it is best to visit regularly at night.

4. Consumables such as fans need to be replaced regularly, and it does not cost much money, which has a great impact on the life of the machine.

Memory reasons. Motherboard reason. CPU reason.

Bad sectors on the disk.

Computers often crash randomly.

And so on and so forth.

After the layer is transformed, the twisted pair is reconnected to the switch, and the fault has been resolved. But how can the new crystal head be oxidized? Later, it was discovered that there was a rice bag under the cabinet where the crystal heads were placed, oh, it turned out that the copper sheet of the crystal heads was oxidized by the steam from cooking.

This incident also reminds us that we cannot ignore the impact of the environment on network equipment and devices.

Fault analysis of Internet café slowing down the Internet speed. Among the many network failures, the most troublesome is that the network is connected, but the network speed is very slow. When encountering this kind of problem, people are often helpless, and the following are the common causes of this failure and how to eliminate it.

Problems with network cables. Twisted pair wires are made up of four pairs of wires that are tightly wound together strictly and reasonably to reduce the effect of background noise or sound. There are great hidden dangers in the network cable that is not made according to the correct standard, and some of them are used normally for a period of time, but after a period of time, the performance decreases and the network speed slows down.

Loop issues. Generally, this situation rarely occurs when the network is small, the number of nodes involved is small, and the structure is not complex. However, in some more complex networks, it is easy to form loops, and data packets will be continuously sent and verified data, which will affect the overall network speed, and it is difficult to find.

In order to avoid this from happening, it is required to develop good habits when wiring.

Broadcast storms. As the main means of discovering unknown devices, broadcasting plays a very important role in the network. However, as the number of computers in the network increases, the number of broadcast packets increases dramatically.

When the number of broadcast packets reaches 30, the network transmission efficiency will be significantly reduced. When the network card or network equipment is damaged, the broadcast packet will be sent non-stop, resulting in a broadcast storm and paralyzing network communication.

Port bottleneck. In fact, the router's WAN port, LAN port, and server network card may become network bottlenecks. During peak network hours, network administrators can use network management software to view the data traffic of routers, switches, and server ports to clear bends to determine the location of network bottlenecks and try to increase their bandwidth.

Worms. Worms are increasingly affecting network speeds. This virus causes the infected user to send emails as long as they are connected to the Internet, and the virus selects random documents from the user's computer to attach them to a random address in the user's address book for email.

Spam emails are sent out in queues, and some are piled up on servers by bounces in batches. As a result, some backbone Internet networks are obviously congested, and the local area network is nearly paralyzed. Therefore, Internet café administrators should always pay attention to various new virus notices and understand the characteristics of various viruses; Upgrade the anti-virus software used and install system patches in a timely manner; At the same time, unnecessary services are offloaded and unnecessary ports are closed to improve the security and reliability of the system.

Network management and software and hardware failure analysis of Internet cafes require solid network technology knowledge accumulation and rich troubleshooting experience, so Internet café administrators need to constantly learn to enrich themselves in order to deal with various problems that may arise.

An Internet café is a place for the public to play games online, and after a long time, it is inevitable that there will be various failures. As a network manager, I can be fast.

It is necessary to determine where the fault is and solve it without any hassle. Internet cafes are for profit, so once something appears.

Problems and problem-solving experience are very important, so we should develop the habit of summarizing management experience. For example, which machine is often.

What is the problem, what is generally caused by it, if there is a group of machines that cannot access the network at the same time, it may be the question of which switch.

Questions and so on, after a long time, you have to know these things in your heart. So I suggest that every NMS should have a records management dimension.

The book of the protection log,The problems that have occurred in each machine,How to solve them。 Which machines are updated every day.

The game, what hardware has been replaced, etc., are recorded as archives. If there is a similar problem in the future, you will know it as soon as you flip through the log.

Probably somewhere other than a malfunction. Another is that if you don't do the network management anymore, someone takes over your shift, and you put your management logs.

Leaving it to him will allow the new administrator to quickly grasp the basic situation of the Internet café machine and network.

The common problems of Internet cafes are divided into three parts: software, hardware, and network. I'm going to put together some of the easy-to-come, classic questions.

Let's talk about it, I hope it will be of some help to the technicians of the Internet café.

Software problems can generally be divided into faults in the operating system itself and gaming problems. The former is manifested as not being able to start the machine and run.

Slow speed, can not automatically shut down and other phenomena; The latter manifests as the game cannot be accessed, cannot be connected, or there is no sound, etc.

There are many reasons for operating system problems, such as driver mismatch, virus infection, system file corruption, etc., due to space.

The limits and levels are limited, and it is impossible to explain them all clearly, so I will explain to you the common ways to solve system problems.

restore

This command is a command to restore the registry, press f8 when you boot up, choose to enter the pure DOS mode and enter scanreg restore, the screen will list the 5 registry files that the system has recently backed up, you can put the nearest note that can start the machine normally.

The registry file is selected, and the registry will be replied after the press return is restarted. If you boot up and find that the graphics card driver is missing, or hit it as soon as it starts.

Open a number of web pages, etc., generally caused by a registry reading error or illegal modification of the registry, you can use this life first.

Let's try recovering the registry.

This command is the one that starts the System File Checker. Type sfc in the Start menu to start the program.

Generally, select "Scan Changed Files", and it will find out the corrupted files and prompt you to reply. You just have to.

Specify the win98 installation directory and it will automatically extract the correct system files to overwrite the corrupted files. It's a sutra.

If you find that the system cannot be shut down properly after killing the virus, it is likely that the virus has infected the system files.

The chassis does not dissipate heat well. Try using silicone.
