As soon as I connected to the Internet, my computer slowed down, and I couldn t turn off the Interne

What exactly do you mean by going to the intranet? Is it access to the company's web or FTP server? Or just copy files from other people's computers and play LAN games?

In addition, is your computer not able to access the intranet, or is the intranet speed slow?

Check your browser's intenet option to delete your history, such as cookies, when you log out.

You can try it out by changing the individual system.

Check whether the DNS settings are correct, then see if your routes are set up normally, and whether the subnet mask and gateway are set correctly.

The first DNS is set to the internal gateway address of the company, and the second address is set to the DNS commonly used on the Internet

Is your computer computer poisoned? If you have antivirus software, kill it, and if you don't have it, install one

That's mostly because of the graphics card -- and there's a virus on your computer or something?

Take a look at the network card configuration and adjust it to 100 Gigabit full-duplex mode.

It is best to use a Layer 3 switch for the intranet, which can improve the speed and reduce the pressure on the router!

And you have to say a little bit more detailed

There are many reasons for computer cards, it is recommended to clean up, there are many reasons for computer cards, first rule out hardware problems and network reasons.

I think it might be computer junk.

Secondly, you can open the case and clean the dust from the host, including the memory on the fan, because too much dust will not dissipate the heat well, and it will also make the computer run too slowly.

Again, it is possible that there is too much garbage on the computer, temporarily using space, resulting in a computer stuck, you can use the garbage cleaning function of Tencent PC Manager to clean up the garbage, Tencent PC Manager a garbage cleanup and scan to clean up.

Hello. Since the NIC system excludes you from wanting.

Considering the problem with your network cable, if yes.

Packet loss caused by network cables has high latency in your network.

Yes yes card It is recommended that you ping the DNS first

If there is packet loss, you can only find it

The department has changed routes.

It may be that there are too many background processes on the landlord's computer, or it may be that the computer garbage has not been cleaned up for a long time.

Then click Computer Acceleration, optimize it after scanning, and then restart the computer, and you're good to go.

Look at the network cable and switch, you get the IT department is fine, prove that the computer is fine, it can only be these two things.

Such a strange question.

You find a separate network card and plug it in.

Most of the time it can be solved.

There is not much money, 20-30 yuan at most.

Try to add an independent network card to try it and see if it works.

It may be a hardware problem, is it a problem with your network cable?

Someone should have controlled your ** traffic, "Is there no one else for your lenient treatment of you to surf the Internet yourself?" It's possible that someone has installed P2P software to limit your traffic! > if no one else uses it with you, then it depends on how many kilobytes you apply for

Remember to take the only one.

Reason for automatic shutdown of the computer:

The computer system is poisoned or malware, the CPU fan is broken, the CPU temperature is too high, the temperature is overheated, the power supply is broken, or new hardware is added, the power supply is insufficient, the graphics card or graphics card fan is broken, the motherboard is broken, the motherboard core is overheated, etc., the computer will automatically shut down.

Auto Shutdown Troubleshooting Methods:

1. There may be a problem with the BIOS settings, enter the BIOS to restore the default settings or take out the battery of the motherboard, reverse the buckle discharge, and wait for 5 minutes to reverse install it. Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2. If the computer shuts down automatically when using a certain application software, the automatic shutdown failure may be caused by this program software, and the program software can be uninstalled.

3. Then check the power supply, the power supply quality is poor, aging or the power is too small, which can not meet the power supply needs of the computer accessories, and the high-power and high-quality power supply can be replaced.

4. Then use the elimination method to check the memory, graphics card, CPU, CPU fan, motherboard, etc.

5. Check the memory, the memory quality is not up to standard, poor heat dissipation, overclocking, mixing and inserting of different brands of memory and the CAS value setting is too low, etc., which can cause the computer to shut down automatically, and the memory parameters can be adjusted accordingly in the BIOS.

6. Check the motherboard, the motherboard aging, capacitor failure or pulp, the motherboard power pins, the motherboard and the chassis backplane short circuit can cause automatic shutdown, you can take the motherboard out of the chassis to check or test, then check whether the CPU fan rotation and the CPU temperature is normal, and then check whether the bottom of the CPU fan heatsink is dry, if it is dry, clean the silicone on the CPU fan, and then recoat the good silicone. If the fan is not normal, replace the CPU fan.

7. Cleaning method: It is a method to eliminate faults by cleaning the dust of the parts in the computer host. Dust is one of the factors that can also cause computer automatic shutdown failures, dust can cause parts aging, pin oxidation, poor contact and short circuit and other failures.

For these faults caused by dust, it is generally more effective to use the cleaning method.

8. The power supply system is unstable, which can also cause the occurrence of automatic shutdown faults, and a UPS backup power supply with voltage stabilization function can be considered.

There are many monitoring software, such as the imonitor eam computer monitoring software that I know can monitor the intranet environment, and can also monitor the external network computer, but cross-network and cross-regional monitoring is required to have a public network environment, and the intranet monitoring is monitored even if the computer is changed to the external network, but the data will be temporarily uploaded out of sync. However, the situation that you said about automatically shutting down the computer after connecting to the external network from the internal network should not be caused by the monitoring software settings, the biggest possibility is that the computer overheats, the computer motherboard protection mechanism is triggered, and the system automatically shuts down or restarts.

Replace it and take a look, it is estimated that the switch is a little faulty.

Try changing the socket on the switch.
