Computer card in hot weather; What is the reason?

Satisfied answer: 7 1% Here are some ways to speed up the computer: 1. Accelerate the start. Every time you start WindowsXP, the blue scroll bar will walk tirelessly for several times. For you who are pursuing high efficiency, do you really hope that it can walk fewer times? In fact, we can completely reduce its scrolling time to speed up the startup. The method is: open the registry editor, expand the branch of HKEY _ local _ machine system CurrentControlSetControlSessions Manager Memory Management Prefetch Parameters in turn, and find the EnablePrefetcher subitem in the right window area, and change its default value from "3" to "1". Next, click "My Computer" on the desktop with the right mouse button, select the "Properties" command, select the "Hardware" tab in the open window, and click the "Device Manager" button. Expand the IDEATA/ATAP controller in the device manager window, double-click the auxiliary IDE channel option, select the advanced tab in the pop-up dialog box, change the original "automatic detection" to "none" in the device type of device 0, and exit after confirmation. The modification method of "main IDE channel" is consistent. Now restart the computer, and your scroll bar will take less time to scroll. Note: Friends who use the VIA chip motherboard must not modify the "VIABUSMASTERIDECONTROLLER" option. In addition, if you don't choose to create multiple different hardware profiles, or want to automatically load the default hardware profile at startup without displaying the list items, you only need to enter "0" in "seconds" in the "Hardware Profile Selection" section. Hold down the space bar when you need to choose, and the list will be displayed. In addition, in the operation, input: msconfig, select the startup item, and check the software that does not need to be started, which can also speed up the startup. 2. Optimizing Online Neighborhood When using WindowsXP online neighbors, the system will first search its own * * * shared directory, which can be used as a printer for the network * *, and then display it after the planned tasks related to the network, which will directly affect the running speed of the computer. If unnecessary, it should be deleted. The specific steps are as follows: Find HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Explore \ Remote Computer \ Namespace in the Registry Editor. Delete {2227A280-3AEA-1069-A2DE08002B 30309D} (printer) and {D6277990-4C6A-1F8D87-00060F5 BF} (. 3. Speed up the power switch. When shutting down in WindowsXP, the system will always send messages to running programs and remote servers to inform them that the system should be shut down, and wait for a response before the system starts to shut down. If you want to speed up the startup, you can set the time to automatically end the task first. The method is: open the Registry Editor, expand the desktop branch of HKEY _ Current _ User Control Panel in turn, find the AutoEndTasks subitem, and set it to 1. Then set the subitem "HungAppTimeout" under this branch to "1000" and change "WaitTOKillService" to "1000" (the default is 5000). Resetting in this way can obviously speed up the shutdown of the computer. 4. Increase the speed of broadband. As we all know, WindowsXP Professional Edition reserves 20% bandwidth by default. In fact, this does not have much impact on our individual users. It is better to make full use of it than to idle about. The method is as follows: Enter gpedit.msc in "Start → Run" to open the Group Policy Editor. Find "Computer Configuration → Management Template → Network →QoS Packet Scheduler", select "Restrict Reserved Bandwidth" on the right, select "Properties" to open the dialog box of Restrict Reserved Bandwidth, and select "Disable". After this reset, 20% of the reserved bandwidth can be released. 5. Clear the redundant hardware information in the system. It is very common to use unplugging hardware devices in daily work. This process of repeatedly installing drivers will leave a lot of hardware registration information in the system, which will slow down the system. You can download optimization software such as Super Rabbit, cclean file and registry. In addition, several methods of Windows XP memory optimization are also introduced for your reference. 1. Turn off the "System Restore" function: right-click "My Computer" and click Properties to open the system properties dialog box. Click "System Restore" and check the "Turn off System Restore on all drives" option. "System Restore" function is an important feature of windows series operating systems. This function was initially limited to: restoring the operating system when there was a problem with Windows operation. In windows XP, we have gone a step further. In addition to restoring the operating system, we can also restore private data, such as Word documents, drawing materials, emails and even browser history materials. Although "System Restore" is useful for people who often make mistakes, it will keep your hard disk in a highly busy state, and you will find that your hard disk is always busy, because Windows XP needs to record operations for future restoration. 2. Turn off the "Remote Desktop" function: Right-click on my computer and turn it off in the Properties option. This function is to let others access your desktop on another machine. This function is not used at ordinary times, so turning it off can reduce the memory occupation. Third, optimize the "visual effect" setting Windows XP is really much better in terms of operating interface, but it takes a lot of memory to look good. If your memory does not exceed 256MB, you'd better optimize your "visual effect" function. Right-click My Computer, click Properties, click Advanced, click Settings in the Performance column, and click Visual Effects. Here you can see all the settings of the appearance, and you can manually remove some unnecessary functions. Fourth, optimize the "startup and recovery" settings. If you find that the hard disk is noisy when the system crashes, it is because Windows XP is writing a dump file. For ordinary users, what is the use of this file if it is not intended to be sent to Microsoft? So it is recommended to close. Right-click "My Computer", click Properties, click "Advanced", click "Settings" in the column of "Startup and Failure Recovery", and the column of "System Failure" is suggested to be changed to "Automatic Restart". With the function of "error report", when there is an error in your Windows XP, the system can automatically collect some error data and send it to Microsoft for improvement. It is recommended to turn it off. Right-click my computer, click Properties, click Advanced → Error Reporting, and then select Disable Error Reporting. Turn off the "Internet Time Synchronization" function. If synchronization is enabled, your computer clock will be synchronized with the Internet time server once a week. Click Start → Control Panel → Date, Time, Language and Regional Options, and then click Date and Time → Internet Time. Seven, turn off redundant services Every time Windows XP starts, many services are also started. Some services are useless to many users and occupy memory. Turning them off is a good choice. Click Start → Run and enter the command "services.msc" to open the "Services" dialog box. (Note: You must log in as an administrator or a member of the Administrators group to complete this procedure. If your computer is connected to the network, network policy settings will also prevent you from completing this step. ClipBook Server: This service allows other users on the network to view your folders. I suggest you start Messenger manually instead: send and receive information on the network. If the alarm is off, it can be safely turned on manually. "Printer Spooler": If the printer is not configured, it is recommended to start or close the error reporting service manually ":Services and applications provide error reports when they run in a non-standard environment. It is suggested to start it manually instead. Fast user switching compatibility ":It is suggested to start automatic update manually instead": This function has been mentioned before, and it can be started manually here. "Network login": handling network security functions, such as registration information. Can be set to start manually. "Network DDE and Network DDE DSDM": Unless you plan to enjoy your office online, change it to manually start NTLM security support ":provide security protection for network applications. It is recommended to start it manually. Remote Desktop Help Session Manager: It is recommended to start it manually instead. Remote Registry: Allows remote users to modify the registry settings on this computer. It is suggested to start it manually instead. Uninterruptible power supply ":It manages your UPS. If not, start it manually or simply shut it down. "Windows Image Capture (WIA)": It provides image capture for scanners and cameras. If you don't have these devices, it is recommended to start them manually or simply turn them off. Close unnecessary programs, especially those that have been started. Also, the registry should be deleted (you can download a super rabbit to delete the registry). It can help you clean up and restart. That's all. There are also seven common reasons that affect the speed of computers. After solving them, you can enjoy the high performance of the computer with peace of mind ... delete the resident program-what is the resident program? Resident programs are programs that are loaded at startup. These programs are called resident programs. Resident programs will not only slow down the startup speed, but also consume computer resources and memory faster. Generally speaking, if you want to delete the resident program, you can delete it in the "startup" list, but if you want to be more detailed, such as icq, popkiller and other software, you can't delete it in the "startup" list, but go to "affiliated applications". Then go to System Tools, and then go to System Information. Press the tool in the toolbar above. Press "System Configuration Editor" again, and it will be listed in detail in the "Start" dialog box after entering. After the computer has been used for a period of time, the running speed of the program is getting slower and slower, blue screen and crash appear from time to time, and the noise is getting louder and louder when the computer is running ... The beloved computer is no longer the original color. What's going on here? This is mainly because you don't have computer maintenance. Computers also need regular computer maintenance to ensure their normal operation. If you don't know how to do computer maintenance, let's do it together. Computer maintenance-cleaning hardware After a long time of computer use, dust and other dirt will accumulate inside and outside the fuselage, causing damage to the computer. So it is very necessary to clean up the computer at ordinary times or for a period of time. First, the computer maintenance of cleaning tools does not need very complicated tools. For general dust removal and maintenance, you only need to prepare a cross screwdriver, a straight screwdriver and a paint brush (or an oil painting pen, which is easy to depilate and not suitable for use). If you want to clean the inside of floppy drive and optical drive, you need to prepare lens rag, hair dryer, anhydrous alcohol, absorbent cotton ball, clock screwdriver, tweezers, leather tiger, paper clip, clock oil (or sewing machine oil) and butter. 2. Precautions 1. Before opening the case, please confirm the warranty period of the computer accessories. Note: During the warranty period, it is recommended not to open the chassis of the brand machine for cleaning, because this means losing the right of warranty. During the warranty period, you can take the brand machine to the maintenance point and ask professionals to carry out internal dust removal. 2. Pay attention to handle with care when you start work, because all parts of the computer belong to precision instruments, and if you accidentally fall to the ground, you will die. 3. Pay attention to the orientation of each patch cord during disassembly, such as hard disk cord, floppy drive cord and power cord, so as to restore it correctly. 4. When fixing all parts with screws, aim at the position of the parts first, and then tighten the screws. Especially the motherboard, a slight position deviation may lead to poor card contact; The uneven installation of the motherboard may lead to poor contact or even short circuit between the memory module and the adapter card, and even deformation and failure over time. 5. Because the integrated circuit devices on the computer board are mostly manufactured by MOS technology, this semiconductor device is quite sensitive to electrostatic high voltage. When people or things with static electricity touch these devices, they will release static electricity, and the released static high voltage will damage these devices. Pay special attention to electrostatic protection when maintaining the computer. Get the tools ready and know the precautions when operating, then you can start cleaning the computer. Because the chassis is usually placed under the computer desk, it is usually not very clean and hygienic, and dust and dirt are easy to attach to the chassis shell. You can first remove floating dust with a dry cloth, then wipe off some stubborn stains with a cloth stained with cleaning agent, and then gently brush off the dust on the surface of various interfaces on the back of the chassis with a brush. 30 seconds to clear the garbage from your computer (make your computer fly like a fly)

To surf the internet easily and smoothly, have you found that the available space of your computer system disk is decreasing day by day? Are you getting slower every day like the old monkey king?

That's right! During the installation and use of Windows, there will be a lot of junk files, including temporary files (such as *). Tmp and *. _mp), log file (*. Log), temporary help file (*. Gid), disk check file (*. Chk), temporary backup files (such as *. Old and *. Bak) and other temporary documents. Especially if IE's temporary folder "Internet Temporary Files" is not cleaned for a period of time, the cached files sometimes occupy hundreds of MB of disk space. These LJ files not only waste valuable disk space, but also make the system run at a snail's pace. I believe you can't stand this! Therefore, it is necessary to clear up the blockage of LJ files in time, keep the system slim and surf the Internet easily and smoothly! Come on, friends, let's go to cclean quickly now! !
