HELP computers have slow internet speeds and are old and motionless

The reason for the slow network 1 is that there is a virus, check and kill it 2 the network cable is not in good contact, so that the telecom changes the line 3 the network resources are insufficient, and there is an unstable situation 4 dust killer: too much dust in the machine will also cause a crash. Clean the chassis regularly.

There are several reasons why the computer is running slowly, one is that there are too many system junk files, and you can use the next optimization software to remove the system junk, such as Super Bunny.

This is the **address) the second is that there are too many disk fragments, you need to be organized, you can start to ,,, programs,,Attachments,,System tools,,Defragmentation,,The third is that your subsystem has been used for a long time,Redo the system regularly,Need to reinstall the system,You can go to this **next system,Use the virtual optical drive or directly unzip and install。

Fourth, the CPU temperature is too high, make a bigger fan, and then clean up the dust of the chassis, 5 is a virus, try the overall antivirus, 6 is the relationship between your machine configuration, about this, I suggest that you don't use any killing software, let the system run naked, the hardware plus root memory will be better, I hope it will help you 7 can be properly overclocked, go to the next overclocking software on the Internet 8 boot less load point boot startup items, turn off unnecessary services 9 system resources are exhausted less open programs or add memory to replace the CPU 10 Slow network speed If the XP system is in use, you can increase the broadband speed through Group Policy, by default, the Windows XP system will retain the broadband of the network connection 20, if you are constantly surfing the Internet, it is necessary to remove this limitation. Start - Run, enter " in the run dialog box and press Enter to open the Group Policy window. in the list on the left side of the Group Policy window"Local machine policy"- "Computer Configuration" - Administrative template"——"Networking"——"QoS packet scheduler"and find the "Limit Reserved Bandwidth" option in the right window.

Double-click the option, select the "Disabled" single option in the dialog box, and press OK. 11 The virtual memory is not set correctly The specific setting method is to 3 times the actual memory (more than 1G does not have to be set) --Fei Ōfei Answer--- Plagiarism is shameful--- plagiarism must be reported--- thank you--- I wish you happiness and health.

Slow network speed in China is not an individual problem, is a national problem, because the Chinese population is large, there are many computers, so network resources are diverted, or for example, like a highway, when there are many cars, the same blockage, is this reason, if you play LAN games in Internet cafes will never be stuck, or some games such as Crossfire or something, the server is located in a certain Internet café, you will not be stuck when you play there, that is because the line is close and smooth.

Let's reinstall your computer! Mine is so good! Of course, hopefully you're not using a wireless card.

Hehe! What do you want to ask?

Reasons for slow internet speed.

1.Viruses and Trojans can cause slow network speeds.

3.Multiple computers share the Internet, and the computers in the shared network may have ARP virus, the solution is to find the source of the attack and use Kingsoft Guard to disinfect the computer.

4.Another is the broadband environment you are in, it is possible that the broadband line is aging, and the router is broken, resulting in slow network speed.

5.Your computer and ** are in a different network environment, such as the access between Netcom users and telecommunications**, and the network speed will also slow down.

6.There is also a problem of **itself, the quality of the server is very poor, and the network speed is slow due to limited bandwidth.

A solution to a slow internet connection.

First of all, it is ruled out that the network speed is slowed down due to external factors, such as the problem of its own dust, and the aging or damage of broadband environment equipment. If external factors are excluded, then internal factors are addressed.

First, Kingsoft Guardian can easily help you repair the incurable disease of IE components being damaged caused by virus Trojans.

1. Enter the main interface and enter [Trojan].

2. Then click [Quick Scan].

Second, first check whether your computer is attacked by the ARP virus, first ** Kingsoft Shell ARP Firewall, if there is an ARP virus attack on the LAN, Kingsoft Shell ARP Firewall will alarm, prompting the attack from which IP computer is issued, and then contact the network management to use Kingsoft Guardian to kill the attacking computer.

Three,.If there is no virus problem, then check to see if there is a program that is taking up a lot of bandwidth and slowing down your internet speed.

How it works: 1. Open Kingsoft Guardian and enter the "System Optimization" tab.

2. Turn on the "Traffic Monitoring" function, find the program that occupies a large amount of traffic and end it. Staring at Zen.

Well, there should be a problem with the wireless network, call someone to fix it?

If the security type of your wireless router is WEP, the key may be stolen by someone else. It would be better to change the security type to wpa-psk. Not before.

Don't leave it on every day, turn it off when you have free time.

If you want to be fast with a computer:

1. Make sure that the computer system is virus-free;

2. Try to install the pure version of the system, try not to install the ghost version;

3. Make the partition reasonable (try to increase the C disk);

4. Install non-core applications under the D drive;

5. Make the drive complete and optimal (try to drive the original factory);

6. Clean up the startup items;

7. Clean up system plug-ins and factory pre-installed plug-ins;

8. Modify the self-test time (30 seconds to 2 seconds);

9. Set the best performance of the system instead of the best appearance;

10. Clean up disk fragments regularly (SSD can be ignored);

11. Try not to set a personalized wallcloth (if it is a solid state drive, it can be ignored);

12. Clean up the background garbage regularly;

13. It is best to match the system windows

update (individual options can be exceptional, e.g. IE version);

14. It is best to get the system security vulnerability patches (netframework is very important);

15. Set the maximum memory of the machine;

16. Clean up the IE cache every 10 months;

1. Add memory on hardware (preferably with the same brand, the same specifications, the same capacity, and the same particles, to achieve dual channels);

2. Install an SSD as a system boot disk (SSD is better than 7200 RPM HDD, 7200 RPM HDD is better than 5400 RPM HDD);

3. Replace the CPU within the range supported by the motherboard

Take care to prevent overheating);

4. If it is an integrated graphics card, then replace the discrete graphics card (the general notebook cannot be replaced);

Change the network cable, if the network cable is fine, then it is a computer problem.

Hello. In your case, please analyze and solve it from the following aspects:

1 To keep your computer normal and free of viruses and malware, it is recommended to regularly use 360 Guard, Kingsoft Guard and other tools to clean up system junk and temporary files (IE cache) generated by the Internet, and check and kill malware. Restart your computer when you're done.

2 The cat has been left open for a long time, it is very hot and hot, it is recommended to place the cat in a ventilated place as much as possible, and do not overlap with the router. So as not to be too high, otherwise there will be a fake crash, restart the cat is better, it is really not good It is recommended to change a cat with good performance (I hit ** to telecom, free to change).

3 Several computers share the network, because the router is too poor, others use P2P to watch movies, etc., it will drag the router to death, restart the router will be better, the long-term solution is to change to a better enterprise-level router.

4. Change the IP address to static settings to avoid slow computer startup, and after the IP lease expires, the sub-configuration will not be able to IP, and the network will be disconnected.

5 If someone has installed and used rate-limiting software on the network, it is recommended that you enable the ARP firewall (360 has ARP protection).

6 It is recommended to manage the boot startup items and stop the useless startup items, especially those who look at the **, ** software, run in the background at boot, and account for the network speed. Start-Run-Enter msconfig-OK-Click "Start" in the "System Configuration Utility" window-Start, except for the input method (ctfmon) and anti-virus software, the general program can be turned off. You can also use 360 and other software to intelligently optimize boot acceleration.

7 It is recommended to install only one main antivirus software, installing more than one will occupy the computer's resources, which will make the computer slower and the Internet will feel slow.

Hope it helps!!

I don't understand hi I !!

I can teach you to analyze and solve the problem step by step!!
