Plug in the network cable The machine is stuck, just unplug it

It is recommended to install an optimization software, personally recommend XP Explorer, which has a lot of optimization settings, including shutdown speed.

I have installed all three computers, and after optimization, the XP boot rolls 1 and a half to 2 turns, and the shutdown is within 10 seconds (see the hardware configuration).

Install the framework first

Good luck

Summary. The problem of slow network speed needs to be tested specifically, otherwise it is difficult to find the fault point: 1. First of all, the stand-alone device is connected to the telecom optical modem and other equipment to ping the gateway or DNS server address of the telecom, and a numerical value is obtained; 2. Connect your router again (unplug other people's network cables) and then ping; 3. Then connect to someone else's computer and ping when it is in normal use; Get 3 values, which is larger or has packet loss, it means that it is the problem of **, the first time is that the telecommunications company line is not good, the second time it means that your router has a problem, and the third time if it is abnormal, it means that your LAN has a problem.

The problem of slow network speed needs to be tested specifically, otherwise it is difficult to find the fault point: 1. First of all, the stand-alone machine is connected to the telecom optical modem and other equipment to ping the gateway or DNS server of the telecom to the vertical shielding address, and a value is obtained; 2. Connect your router again (unplug other people's network cables) and then ping; 3. Then connect to someone else's computer and ping when it is in normal use; Get 3 values, which is too large or has packet loss, it means that it is the first problem, the first skin disturbance is the telecom company's line is not good, the second time it means that your router has a question, and the third time if it is abnormal, it means that your LAN has a problem.

Unplug the router and plug the cable into the port, and the network speed will be very slow.

Try it differently.

There is only one mouth.

That's the setup issue. Restart it and set it up according to the above method.

Summary. Unplugging the network cable in an Internet café may cause it to freeze because the network connection is suddenly interrupted while playing a game or application, resulting in a communication problem between the client and the server, resulting in the program not functioning properly and responding. In this case, the client keeps trying to reconnect to the server, but the network connection is interrupted and the client cannot reconnect properly, causing the program to freeze or crash.

In addition, in some cases, unplugging the network cable in an Internet café may also cause problems in the computer system, such as system file loss, corruption or virus attack.

Unplugging the network cable in an Internet café may cause it to freeze because the network connection is suddenly interrupted while playing a game or application, resulting in a communication problem between the client and the server, resulting in the program not functioning properly and responding. In this case, the client will keep trying to reconnect to the server, but the client will not be able to reconnect normally due to the network connection being interrupted, resulting in the program freezing or crashing. In addition, in some cases, unplugging the network cable in an Internet café may also lead to problems in the computer system, such as the loss or corruption of system files, or virus attacks.

You've done a great job! Can you elaborate on that?

Therefore, it is recommended not to unplug the network cable at will when using the network potato to avoid damage to the system and programs. If it is necessary to interrupt the network connection, Wang Shou Burial can be achieved by closing the program or disconnecting the network connection normally.

It may be caused by a short circuit in the NIC interface, check the network cable or replace the NIC interface.

There are a lot of factors for your question, and my analysis is:

1.It is difficult to determine if you are not at the scene, plug in the network cable and check whether there is a data packet received or sent. Try uninstalling the network card.

Sometimes this situation is caused by DHCP problems and the computer is set to automatically obtain the address. Use ipconfig to make sure that the IP address you manually configured is successfully matched.

2.Reinstall the network card after uninstalling!

If there is still a problem, it is that your machine virus is seriously taken seriously, and the router or switch refuses to access!

3.If the NIC does not respond, it may be caused by an ARP attack on the DHCP server that the NIC keeps sending DHCPDiscover packets to the DHCP server. If your organization's DHCP server has IOS configuration on the switch, find the network manager to see if there is corresponding isolation of your MAC address.

Go to the network properties and remove the two small cells.

4.There is a problem with the network card driver (it is recommended that you adjust the network card speed to 10m and a half) If you say that, the card can't move when you connect to the Internet, 80 is a virus.

Is your network cable slow?,And your system is not good.。

If the display screen is not displayed, check the display first to display the card.

1 Whether the monitor is connected normally, and whether there are multiple input buttons (move them all).

2 Whether the graphics card is connected normally (if necessary, turn on the host, unplug the graphics card, use the eraser to polish the memory gold finger, and then plug it in).

3 Without a monitor Whether the graphics card can pass the boot check (there will be when the boot check passes.)"Drops"A bang. If you can, confirm that it is a display graphics card issue).

4 Whether there are other prompt tones (if so, you can check the memory, etc.).

5 Whether the bare metal operation (with motherboard only) can be checked by boot (if not, it is a motherboard problem).

Motherboard issues are more troublesome. Other plates are polished with an eraser and re-fastened (sometimes multiple times) before use. If the same problem occurs multiple times, the board should be replaced.

Then it's stuck to a dead end, so restart it.

There are still many reasons for the death of the electric belt filial piety brain.

1. The antivirus software is installed more, and all the monitoring is turned on, less monitoring is turned on or not monitored, and the virus is often checked and killed.

2. The software or driver is not compatible with the system, reinstall or upgrade the driver.

4. Memory, graphics card, and voltage instability can also cause crashes (if the memory is too small, add a memory module).

5. The temperature of the common CPU or graphics card pants and other hardware is too high, which is most likely to cause card and crash.

6. If the hard disk has bad sectors, use software to repair the bad sectors of the hard disk, format the hard disk, repartition and reinstall the hard disk, and replace the hard disk.

7. Stupid pure manuscript upgrade hardware causes incompatible crashes.

1. Restore the router to factory settings and then reconnect it, if it doesn't work, start the second step; Code 2, the interface connection is not plugged in, check the re-Chi Hongxin plug it in. 3. Borrow another computer to try whether it is normal to surf the Internet, if you can access the Internet normally, then uninstall your computer network card driver and then reinstall the network card driver. It stands to reason that if you surf the Internet on a home router, other computers can normally be on your computer, and you can't, that's the problem of your system itself.

Reinstalling the NIC driver should resolve the issue.
