Why is my computer so slow!! ！！！

Send you a few words:

Reinstall the system.

If it's always been like this, there are several possibilities:

1. It may be because the configuration of your machine is not good (you should consider upgrading the hardware);

2. It may be that the bandwidth you access is not enough and the Internet speed is slow. If it's been like this recently:

If it's something like this recently, it could be:

1. It may be poisoned, you can find something suspicious in the "Task Manager"; Or use the "Internet Assistant" to analyze and process;

2. It may be that your hard disk is running out of free space, and you should clean up the disk;

3. It may be that you have too many "temporary Internet files", consider cleaning up;

4. Is the webpage you are opening too big? You can just open the text;

In addition, some malicious** may also affect the speed of opening a web page.

Clean up your computer with a tool such as Internet Assistant or Optimizer.

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. 3. If there is a system problem or a Trojan, check and kill the Trojan, restore the system or reinstall it (**win cleaning assistant to check and kill the Trojan).

4. Memory, graphics card, and voltage instability can also cause crashes (if the memory is too small, upgrade the memory). 5. Generally, it is common to have a slow CPU or graphics card and other hardware temperatures that are too high, which is most likely to cause cards and crashes. 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. Upgrading the hardware causes an incompatible crash. 8. Too many junk files, too many disk fragments, too many old models, etc.

First of all, the CPU, your CPU is too weak, the performance is not enough, the hard disk is too small, and the speed is not high enough, and the hardware is basically these two problems. In terms of the system, it is necessary to clean up junk files frequently and clear the boot items of Sun Zhengli, so that the problem of slow boot can be alleviated. By the way, LZ, are you really 4 years ago?

40G hard drive. then the first repentance.

The other main configurations of your computer are OK, but there is one thing that you may have overlooked, and that is the hard disk. Now many people say that it doesn't matter if the amount of hard disk capacity is large, it mainly depends on other configurations, but, in fact, this is not the case, the main difference between the hard disk of n years ago and the current hard disk is not his capacity, but his cache, compared to the hard disk of n years ago, the cache of the hard disk is actually slow with the current memory card, and how can you afford to play a large game.

Although the CPU performance is not very good, it is still good to play games, so there is no need to say that it is as bad as upstairs.

There could be many reasons for this.

1. Hardware incompatibility (detect hardware compatibility problems).

2. Computer poisoning (check and kill all of them, don't do anything else after completion, restart them directly) 3. Computer hardware aging.

4. If the heat dissipation is not good (check whether the power supply and CPU fan are in good condition), open the main chassis and use a hair dryer to blow off the dust inside.

There are many reasons for this, (the system, and the CPU temperature is too high).

The temperature is too high, change to a low temperature environment and lower the temperature inside the host.

If there is a problem with heat dissipation, see if the fan is revving, and look at the speed setting in the BIOS.

The cup fan is broken, it's a heat dissipation problem.

Use the system that comes with the system restore method:

The system comes with the system restore: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click Next Restore (win7 restore the system, in the control panel then the device and security sub-option and then the backup and restore sub-option).

Next Master Lu, look at the temperature, if the temperature is not high, change the system, if the change system is not good. Move the computer city to see if the power supply is good, you can open the back cover to see if the capacitor on the motherboard has burst.

Is it your slow internet or something?

First of all, you rule out whether there is a problem with the cat, such as too much heat affecting the network speed, change a friend's cat to test, detect the line, if the cat is fine, the rest is basically a problem of movement, check whether the computer is virus, you can be diagnosed.

Let's kill the virus first""The way to improve the speed of the computer is as follows: The optimization is useful, and my suggestions to you are as follows: 1. Reinstall the system XP, your computer has been applied for a long time, there are too many software games, and the deletion is not clean (mainly in the registry), there is a lot of redundancy 2. Don't use the latest operating system and software, I have been office2003 and cad2004 3. There are no files on the desktop (if you want to find convenience, store them in other disks, and then put the shortcut of the folder on the desktop) 4. Don't do anything useless in the startup item 5. Dust it, there is too much dust in the chassis If the above is not successful, it will be replaced with a new one"

Suggestion 1: Detect and kill malicious plug-ins 360 Guardian and Windows Cleaner Assistant to cooperate with the application, and the effect should be good! They are all experts at dealing with malicious plugins.

Suggestion 2: Optimize the system Optimize the startup speed of the computer, enter msconfig pc-csr and special stickers in the operation, please do not**.

Text description of ** Optimize computer startup speed 1Start --> run --> enter msconfig and press enter -- > start (top row and far right) -- only tick ctfmon in front of it, apply OK --> de-> tick the dialog box that appears -->OK 2My computer right-click on the properties --> Hardware--> Device Manager--> click on the plus sign before opening the IDE --> double-click on the primary IDE channel (the same setting for the secondary IDE channel)--Advanced Settings--> set the device type to None (can be set, operate like this)--Set the transfer mode to DMA--> the plus sign before clicking on the port -->Disable LPT1,COM1,COM2 inside (for no printer at home)--Floppy disk controller is also disabled.

First of all, check and kill viruses and Trojan horses to see if these are doing the trick. If not, then it's up to optimization. (Security Guard 360 Windows Cleanup Assistant) If the moderator is unwilling to reinstall and upgrade the hardware, then try to work the software and system, and in terms of optimization, the more famous ones are the optimization master and the super rabbit moderator can try.

1. Don't load too many random startup programs (a must do to increase the boot speed) Don't load too many unnecessary random startup programs when you boot up. Select "Start Program Attachment System Tools System Information System Information Dialog", and then, select "Tools System Configuration Utility Start", you only need to check the antivirus and Trojan horse program before checking, and other items can be unnecessary, and you can make sure to start again after selection. (The notebook must also be checked on the notebook program) 2. Don't use the background lightly Don't use ActiveDesktop, otherwise the system will slow down (right-click on the screen to find the display properties web tab and cancel all the options about "Active Desktop" and "Channels").

3. Set the virtual memory to set the virtual memory to be 3 times the memory of the machine, for example, if there is 32M memory, set the virtual memory to 96M, and the maximum and minimum values are the same (this setting can be set through "Control Panel System Performance Virtual Memory"). 4. Some optimization settings a. Go to the control panel and select "System Performance File System".

Change the "Primary Purpose of Computer" tab of the hard disk tab to "Web Server", "Read-ahead Optimization.""Turn to full speed. b. Cancel the "search for a new floppy drive every time you start" in the "Floppy Disk" tab. c. Adjust the "Additional Cache" in the CD-ROM to the maximum, and select the CD-ROM with 4 times the speed or faster as the access mode.

Windows XP calls many services that users may not use at all, and these services not only affect the speed of operation, but also very detrimental to the security of the system. As a result, unnecessary system services can be disabled as needed. Methods :

Select"Get started"menu"Run", enter""Open"Service Management Console"to start or stop the service by changing the start type of the service. 7.If you feel that the single-window browser of Windows is slow, you can improve it by :

Open"My computer", click"tools"->"Folder options"->"Check", selected"Use a separate process to open the folder window"。This prevents a slower device from affecting the responsiveness of the user interface.

1 Periodically, clean up the dust in the computer, open the chassis after shutting down, use a hair dryer, and blow cold!!

2 Usually use tools such as 360 Guardian and Kingsoft Guardian to clean up system garbage and temporary files (IE cache) generated by the Internet, and check and kill malware.

3 The computer configuration is poor, try to set the virtual memory to a larger one, (xp) right-click on my computer Properties Advanced Performance ......There the settings are advanced to change.

In the custom there is set to 2000 - 4000

Win7) Computer - Properties - Advanced System Settings - Performance Settings - "Advanced" Tab - Virtual Memory - Change - Select the drive C drive you want to set, select the system management size or select the custom size as you need - Settings - OK.

4 Antivirus software installation takes up a small amount of resources, such as NOD32, or only one auxiliary antivirus software is installed.

5 Try to set the IP to a static IP, which can reduce the startup time of the computer and the reflection time after entering the desktop.

6 Don't put too many files and icons on the computer desktop, which will slow down the computer's response, and try not to install the software on the C drive.

7 Close some startup programs. 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.

8 It is recommended to install only one main antivirus, as installing multiple will take up computer resources and make the computer slower.

9 Regularly defragment the disk, open my computer To defragment the disk of the drive - Properties - Tools - select the defragmented disk to open the "Disk Defragmenter" window - Analyze - Defragment - the system will start to defragment.

10 Install a computer optimization software such as Optimizer or Super Rabbit, and the computer will be much faster under optimization!!

11 The current system also occupies a large amount of memory, and if necessary, adding more memory will be much faster.

12 The computer hard disk will be used for a long time, it will also make the computer slower, repartitioning and installing can fix the logical bad, the computer will be faster, and the physical read and write speed of the hard disk is slow, and it can only be replaced with a better !!

Hope it helps!!

I don't understand hi me!!

A white screen flashes every time you click, what does this mean, and what antivirus software do you use?

Is your internet speed slow? You use a different network, right?

You try the next driver of life and see if your hardware is updated wood.

If it's me, I'll reinstall the system first and take a look.

1. Clean up and defragment disks.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary files, start-run-enter.

temp%-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig--- start.

In addition to anti-virus software and input methods, general programs can be turned off.

5. Delete unused program software.

6. Defragment Disk - Start.

2. Upgrade the graphics card and network card driver.

3. Increase the physical memory, replace it with high-quality memory, and set up virtual memory reasonably.

1. To play games, the virtual memory can be set larger, the minimum value is times of the physical memory, and the maximum value is 2-3 times of the physical memory.

No matter how big it is, it takes up too much space on your hard drive.

2. The virtual memory setting method is as follows:

Right-click on My Computer--Properties--Advanced--Performance Settings--Advanced--Virtual Memory Change--Select the partition where the virtual memory (page file) is stored in the drive list--Custom size--Set the values in "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, and the hard disk resources are insufficient, resulting in insufficient virtual memory.

Finally, optimize your computer with Optimizer or Super Bunny.
