How to maintain your home computer and keep it running normally

The computer indicates that the virtual memory is insufficient.

1. Infected with the virus!

Some viruses take up a lot of memory space when they break out, causing the system to run out of memory. Hurry up and go to the antivirus, upgrade the virus database, and then get the antivirus measures right!

2. Improper setting of virtual memory.

Improper setting of virtual memory may also lead to the problem of insufficient memory, under normal circumstances, the size of virtual memory is 2 times the size of physical memory, if it is set too small, it will affect the normal operation of system programs. Resize virtual memory Take WinXP as an example, right-click "My Computer", select "Properties", then in the "Advanced" tab, click the "Settings" button in the "Performance" box, switch to the "Advanced" tab, and then click the "Change" button in the "Virtual Memory" box, then reset the virtual memory size, and restart the system when you are done.

The virtual memory is insufficient because the virtual memory settings in Windows are too small or the hard disk space where the virtual memory is located is insufficient. It is recommended to place the virtual memory in a different partition from the operating system, and set a fixed size, generally 1 5 times the memory capacity of the system; Right-click "My Computer", select "Properties", pop up the system properties window, select the "Performance Options" tab, click the "Virtual Memory" button below, pop up the virtual memory settings window, click the "User Specify Virtual Memory Settings" radio button, "Hard Disk", please select the partition with a larger remaining space, and then enter the appropriate range value in the "Minimum" and "Maximum" text boxes. If you're having trouble using your system to get the maximum and minimum values, you can choose to "let Windows manage the virtual memory settings", but make sure that the partition where the virtual memory is located has enough space left (more than twice the system memory).

3. Insufficient system space.

The virtual memory file is in the system disk by default, such as the virtual memory file name of WinXP, if the remaining space of the system disk is too small, resulting in insufficient virtual memory, there will also be a problem of insufficient memory. The system disk must reserve at least 300MB of free space, of course, this value depends on the actual needs of the user. Try not to install various application software in the system disk, ensure that there is enough space for virtual memory files, and it is best to place virtual memory files in non-system disks.

4. Because the system user permission is not set properly.

When a Windows system based on the NT kernel is started, the system user creates a virtual memory file for the system. For the sake of system security, some users use the NTFS file system, but the system user's permission to "write" and "modify" in the system disk is canceled, so that it is impossible to create virtual memory files for the system, and the problem of insufficient memory will also occur when running large programs. The problem is easy to solve, just re-grant the system user the "write" and "modify" permissions, but this is limited to the use of the ntfs file system.

Regularly clean junk files, registry redundant information, disk cleanup and disk defragmentation, and patch. Cleaning up plugins and antivirus is essential.

If you do this well, you can ensure normal operation.

Recommendation: Antivirus & Plugins & Patches: 360+ Kaba.

Disk Cleanup and Disk Defragmentation: The tools that come with winds. Open with: Start the Program Accessories System Tools.

Registry redundant information: Optimizer.

Fix the gas and kill the virus, and uninstall the things you don't need.

As long as you put your favorite things on the desktop, they don't take up a lot of memory.

Useless things software is cleaned regularly and is not on the garbage** If it is an old machine, you can consider upgrading.

Keep the surface of the host, keyboard, and monitor clean at all times to avoid dust entry and maintain good heat dissipation. Dust your computer regularly.

System maintenance, use Kingsoft Guardian and other software to regularly clean up garbage, viruses and so on for the computer. Or pretend that the system will reply quickly after the rain and sunny weather. I feel that there is something wrong with the system, and it only takes more than ten seconds for the system to recover.

1.Precautions.

The impact of the environment on the life of the computer cannot be ignored, and the following matters must be paid attention to in order to make your computer run stably for a long time

1) Control the temperature: The ideal working temperature of the computer is 10 35, too high or too low will affect the life of the computer accessories. The computer should be placed in a spacious space, and the heat dissipation space should be reserved around it, and it should not be mixed with other debris.

2) Dustproof: The dust content in the air also has a great impact on the computer, too much dust, and it will corrode the accessories and circuit boards over time; If the content is too small, an electrostatic reaction will occur.

3) Anti-magnetic: Magnetic fields are strictly forbidden around the computer. Magnetic fields can have a serious impact on displays, disks, etc.

4) Control humidity: ideal humidity environment 30% 80%.

5) Anti-static: In the case of a dry environment, you should beware of the influence of static electricity on computer accessories.

6) Shockproof: Do not move the main chassis or make it subject to shock and vibration when the computer is working, which is a very dangerous action for the hard disk.

7) Correct power on and off: the order of power on is: first peripherals (such as printers, scanners, UPS power supply, modem, etc.), if the display power is not connected to the host, turn on the monitor power first, and then turn on the host; The shutdown sequence is reversed

Turn off the console first, then the peripherals.

8) Keep the relevant items.

The driver CD-ROMs and manuals of various computer boards and peripherals should be properly kept, especially the instructions of the motherboard.

Clean up once a day with 360 Security Guard.

It's best to kill the virus once a week and organize the disk.

Equip a Super Bunny and 360 Security Guard and use it once every 2 to 3 days.

Maintenance of the software. Generally, it is two or three days to use 360 Guardian to conduct a physical examination of the system, delete some unnecessary applications and clean up the garbage in time. If there is an abnormality, it is necessary to kill the virus in time.

If it is a problem with the software that affects the normal boot and use, and 360 Guard and antivirus software cannot solve the problem, you should reinstall the system yourself (or ask someone) to reinstall it. Open the computer case every half a month or a month, and use a brush or soft brush and hair dryer to sweep the dust in the host. Sometimes you can't turn on the phone when you encounter the sound of Didi, in addition to cleaning up the dust, you have to pull out the memory module and plug it in again.

If the hardware is broken, such as the power supply is burned, the motherboard is broken, the monitor is broken, the network card is broken, etc. These hardware things, if you are an expert can buy and replace them yourself, if you are a layman in hardware like me, then you can only ask others to repair them.

Clean up the dust inside your computer regularly. There is a lot of dust in our lives, fine hair, etc., our ground is often cleaned, but we do not often clean up the computer, we need to regularly clean the dust in the desktop computer host. Clean your computer's screen regularly.

The computer screen is too dirty, which will affect our vision, so the computer screen should also be cleaned regularly. Clean your keyboard regularly. The keyboard is generally exposed to the air, and it is easy to get dirty after a long time.

Therefore, the keyboard should also be cleaned regularly and kept tidy.

"Defragmenting disk" is also an effective way to change the speed of your computer. It is mainly to organize the system disk c, and you can also clear all the files that are not saved by normal browsing of the web. Update your virus database frequently, upgrade your antivirus, and don't let viruses persist on your computer for a long time.

The most effective means of guaranteeing health. The security of the computer can be checked from time to time. Due to the need to suck air from the outside into the chassis for heat dissipation, after half a year of use, the inside of the chassis will generally be covered with a layer of dust.

If there is too much dust, it will affect the heat dissipation effect of the heating device, and even cause the short circuit of the components to burn the device.

Desktop chassis has many interfaces, pay attention to the interface surface as much as possible to avoid people or objects touching the place. In addition, the interface should be moisture-proof to avoid rust. Pay attention to the cleaning of the host, the host is easy to have a thick layer of ash after a long time, which will affect the normal heat dissipation of spare parts, and clean it regularly, and the individual generally cleans it once a month.

In summer, if the computer is not used for a period of time or for a long time, it can be turned on and standby normally every week or so to avoid damage to the computer caused by humid air. Clean up the computer garbage in time, the antivirus software should regularly clean up the junk software cache, etc., take it out, try to find a flat plane and place it again, try to avoid local stress, and damage local components due to stress.

The so-called "maintenance" may not be so accurate, and we need to pay attention to two aspects in the use of the computer: the software should be installed and used in regular software, timely update patches, regular anti-virus, and timely clean up system garbage; In terms of hardware, it is necessary to pay attention to regular cleaning and maintain a good working environment.

Keep the room where the computer is placed dry and clean, especially the computer, turn on the computer correctly (peripherals first, then the host), and be sure to disinfect the virus before using the CD or floppy disk; If the system exits abnormally or loses power unexpectedly, you should scan the hard disk as soon as possible to fix the error in time. Remember to clean the main unit once in about three months and wipe the monitor clean with lens test strips. Disassemble the back cover of the mouse, take out the ball, wash it with water, use a blowing balloon to clean the dust between the keys of the keyboard, if you have a certain installed base, it is recommended that you reapply silicone grease to the CPU every 5 months.

For the protection of the monitor, try to set a screensaver in case the screen is always on. In terms of system protection for software use, try to install a computer management software to help clean up computer junk and anti-virus regularly. The file is saved as clearly as possible, the system disk does not store files, try to install only software, and the file directory of other storage disks is clearly classified ......For example, it is a good habit to find yourself and find it on the computer.
