<br> Second, the hardware articles <BR> <BR> 1, Windows system itself off the hard disk drive DMA mode DMA mode <BR> <BR> we should all know, the hard drive PATA mode DMA33, DMA66, DMA100 and DMA133 ., the latest SATA-150 are out! .Generally speaking most people now use the model or the PATA hard drive, hard drive using DMA mode PIO mode of transmission compared to the previous rate of 2 to 8 times faster. .DMA mode applies on the performance of the system played a substantial role. .But you know what? .Windows2000, XP, 2003 systems will sometimes turn itself off the hard drive DMA mode, automatic switch to PIO mode! .This has resulted in the use of the above system, a sudden drop in hard drive performance, the most obvious phenomenon: the system was slow starting speed, in general, the normal WindowsXP system starts from left to right movement of the slider bar to go up 2 to 4 times .the system will be able to start, but the problems may take 5 to 8 times or more! .And the hard disk when running the system operation was feeling slow, some large software running when CPU usage reaches 100% and have always pause, play 3D games when some large significant pause screen, the above problem occurs when we are most .Good to see your hard drive DMA mode is not being shut down Windows system itself. .View your system is turned on DMA mode: <BR> <BR> a. Double-click "Administrative Tools", then double-click "Computer Management"; <BR> <BR> b. Click "System Tools", then click "Device .Manager "; <BR> <BR> c. Expand" IDEATA / ATAPI controllers "node; <BR> <BR> d. Double-click your" primary IDE controller "; <BR> <BR> 2, CPU and .whether the normal operation of the fan, and adequate refrigeration <BR> <BR> slow fan speed when the CPU time, CPU itself, the temperature will rise, in order to protect the safety of CPU, CPUwill automatically reduce the operating frequency, resulting in variable speed computer .slow. .There are two ways to detect CPU temperature. .You can use the "finger test method" try finger processor temperature is hot, but it should be noted that this approach must first unplug the power cord, and then take a ground wire to prevent the body with static electricity breakdown CPU .even damaged. .Another more scientific method is to use a multimeter with a sensing device to detect the temperature of the processor. .<BR> <BR> Because the processor type and the model, reasonable temperature varies. .But in general, the temperature should be below 110 degrees. .If you find that the processor tests the temperature higher than that, check the chassis fan running. .<BR> <BR> 3, USB, and the impact of the scanner <BR> <BR> will start all the Windows drive (including drives) were detected, so if you put a CD-ROM drive, the computer will start to extend .time. .So if the computer scanners and other equipment installed or has been connected to the USB startup disk, you may wish to try to put them off, start to see changes in speed is not there. .In general, the slow USB interfaces, so the equipment will speed the computer starts more obvious influence, should try to start after connecting USB devices. .If no USB device, it is recommended that USB will be directly in the BIOS settings turned off. .<BR> <BR> 4, whether to use a disk compression <BR> <BR> because "the disk compression" may cause a sharp decline in PC performance, resulting in the slow system speed. .So then you should test to see if using the "disk compression", the specific operation is in the "My Computer", right click, from the pop-up menu select "Properties" option to check the drive's properties. .<BR> <BR> 5, the impact of <BR> <BR> card if set properly, the network cardwill also significantly affect system boot speed of your computer if connected to the LAN, network card drivers installed by default .automatically through DHCP to obtain IP address, but most of the company's LAN DHCP server is not, so if the user set to "automatically obtain IP address", the system will continue to start the search in the network DHCP server, until you get the IP .address or out, naturally, affected the start-up time, so the best for their local area network computer users to specify a fixed IP address. .<BR> <BR> 6, folder and printer sharing <BR> <BR> installed WindowsXP Professional Edition's computer will also appear when starting very slow, sometimes the system seems to give people the feeling of crashes, login system, the desktop .does not appear, the computer just stop the reaction, 1 minute before normal use. .This is due to the use Bootvis.exe program, which started Mrxsmb.dll file for the computer to add 67 seconds! .<BR> <BR> To solve this problem, as long as the stop sharing folders and printers to: Select "Start → Settings → Network and Dial-up Connections", right-click "Local Area Connection" and select "Properties" window open .Cancel "This connection uses the following selected components" under the "Microsoft network file and printer sharing" check box before, restart your computer. .<BR> 7, system accessories <BR> <BR> poorly configured machine in the assembly some users tend to ignore some small things, resulting in the overall computer accessories with properly, there is the speed bottleneck. .For example some friends of selected high quality CPU, sound card, etc. may have bought a cheap generic, in fact, often do more harm than good. .Because this way the computer running the games, play DVD Audio as CPU-time high and the data transmission speed is slow, or the fundamental need no hardware decoding with software decoding, often caused by the sound of the halt, and even lead to program .run off. .Another example is some friends of the machine is level rise of the past, some of the old machine could not bear to discard components such as memory, installed in accordance with the new machine, but because the old memory of the speed limit, tend to make the new machines must reduce speed to accommodate .it, thereby reducing the machine's performance, which greatly affect the overall speed. .<BR> <BR> 9, disconnecting unused network drives <BR> <BR> Windows in order to eliminate or reduce the need to re-establish the number of network connections, we recommend some of the need to use the network drive off, that is, the "My .Computer ", right-click has been established mapped network drive, select" Disconnect "button. .<BR> <BR> 10, the lack of sufficient memory <BR> <BR> Windows operating system is one of the advantages of the multi-linear, multi-task, the system can use the CPU to carry out time-sharing operation, so that you also do .many things. .But things are beneficial to the natural disadvantages, multi-task operating on your machine will be put forward higher requirements. .You all know that even one of the most common software requirements WORD about the best there is 16MB of memory, and running as 3DMAX and other large software, 64MB of RAM is not enough. .So this time the system will automatically use the hard disk space to the virtual main memory for running programs and storing the swap file, and various temporary files. .Since hard drives are mechanical structure, and the memory is the electronic structure, the speed difference between them several orders of magnitude, which uses hard disk to the virtual main memory will result in a significant reduction in the speed run. .<BR> <BR> 11, hard disk space <BR> <BR> disadvantage of using the Windows platform is one of the document management do not know, you sometimes do not know the usefulness of the file on the system, so Windows directory .increasing the number of files, more and more large-capacity, combined with the current software like bigger and bigger, plus some system-generated temporary files, swap files, all of which makes the hard disk free space becomes smaller. .When a small hard disk space available to a certain extent, it will cause the system swap file, temporary files, the lack of available space, reducing the efficiency of the system. .More important is that we usually frequent the store on the hard disk, remove all kinds of software, makes available hard disk space has become fragmented, so the system often does not store files in sequential order according to storage, which will cause the system to store and read .files, and moving heads, which greatly reduces the system speed. .<BR> <BR> 12, hard disk partition too many mistakes <BR> <BR> Windows2000 if you do not upgrade to SP3 or SP4, and too much define the partition, then also will start to become very long, even .hang. .It is proposed to upgrade the latest SP4, also best not to drive too many sub-areas. .Because Windows must be loaded at startup for each partition, with the number of partitions increases, the amount of time to complete this operation will continue to grow. .<BR> <BR> <BR>.
