It is a common heart disease for every computer fan to suspect that the computer is starting too slowly. Here is a brief introduction to the computer startup that Xiaobian collected to speed up the fifteen strokes. Some of them have not been tried, and we have discussed it. First, the bios optimization settings in the bios settings home page we enter the "advanced bios features" option, move the cursor to the "frist boot device" option, press “pageup” and “pagedown” select, the default value is "ld" ; floppy”, which means that the system will first read the boot information from the floppy drive at startup, which will lengthen the boot time of the machine and shorten the life of the floppy drive. So we have to choose “hdd-0” to boot directly from the hard disk, so it will start for a few seconds. In addition, for the bios settings, “above 1mbmemorytest” is recommended to select "disabled", for "ldckpoweronselftest", it is recommended to select enabled. The setting in the "advanced chipset features" item has a great impact on the acceleration of the machine. Please pay more attention. Change “bank 0/1 dram timing” from “8ns/10ns” to “fast” or "turbo”. “turbo” is faster than "fast", but not very stable, it is recommended to choose "fast". If the memory quality is good, you can choose “turbo”; try, unstable can be changed back to “fast”. For memory quality, it is recommended to set it to “2” in the “sdram cas latency" option to speed up. Newer motherboards support agp4x. If your graphics card also supports agp4x, then activate this option at “agp-4xmode”, which is selected as "enabled", which will better play the graphics card's capabilities. Speed up system startup. Second, start dma mode, improve hard disk speed udma/33, 66, 100 technology hard disk maximum transfer rate is 33mb /s, 66mb /s, 100mb /s, in theory is ide hard disk (here refers to pio mode4 mode The transmission rate is 3-6 times of the transmission rate of 16.6 mb/s. However, in the default setting of windows, dma is disabled, so we must open it. The specific method is: open the "Control Panel & Rarr; System & Rarr; Device Manager" window, expand the "Disk Drive" branch, double-click the udma hard drive icon, enter "Attributes & Rarr; Settings & Rarr; Options & rdquo;, in “dma” items in front of &&quo;√”, then press OK to close all dialogs and restart the computer. Third, remove the boot logo of windows First you have to open “ start & rdquo; & rarr; & ldquo; set & rdquo; → & ldquo; binder options & rdquo;, from the "view" & rdquo; tab in the "advanced settings" list box Check "Show all files" in the box. Then open the c drive, find the msdos.sys file, and cancel its "read-only" attribute, open it, under the "option" paragraph, add a line statement: logo=0, so the windows boot pattern It will not be loaded and run, and the boot time can be shortened by 3 seconds. Fourth, optimization & ldquo; start & rdquo; group computer beginners love to try a variety of software, it will be deleted in a short time, but often because of some inexplicable reasons, these software will also reside in the "start" project Medium (especially when using some d-version software), windows will waste a lot of time for this. To solve this problem, it is very simple. You can open “Start”→“Run”, in the dialog box that appears, click "Enter" and click "“" ”, will bring up the "system configuration utility", click on the "start" label, will not need to load the startup group in front of the program "ld"; √ & rdquo; remove it. In this way, at least the startup time can be shortened by 10 seconds. Fifth, finishing, optimizing the registry windows after booting, the system must read the relevant information in the registry and temporarily stored in the ram (memory), windows spent most of the time, spent on this. Therefore, it is necessary to organize and optimize the registry. For optimization of the registry, you can use software such as windows optimization master. With Windows Optimizer, click “Registration Information Cleanup"→“Scan”, the software will automatically clean up the garbage in the registry for you. After the scan is finished, a menu will pop up for you to choose whether to back up the registry. It is recommended to select a backup, and then click “Clear & rdquo; after backup. 6. Frequent maintenance of the system If too many games, too many application software, and too many old materials are installed in the system, your computer will run slower and slower, and the boot time will be longer and longer. Therefore, it is best to do a comprehensive maintenance of the computer at regular intervals. Click “Start”→“Programs”→“Accessories”→“System Tools”→“Maintenance Wizard”, then click the “OK” button to proceed to the computer A comprehensive maintenance will keep your computer in top condition. For the hard disk, it is best to do a "disk defragmentation" every 2 weeks, which will significantly speed up the program startup speed, click & ldquo; system tools & rdquo; & rarquo; & ldquo; disk defragmentation program rdquo; Note that the disk where the system is located must be sorted when defragmenting the disk, so that the order of windows startup can be really accelerated. 7. Expand the virtual memory capacity. If your hard disk is large enough, please open the “System” in the “Control Panel” and open the “Virtual Memory” option in the “Performance” option. Two items: The user sets the virtual memory setting, points to a less-used hard disk, and sets the maximum and minimum values to a fixed value, which is about twice the physical memory. In this way, when the virtual memory is using the hard disk, it is not necessary to accommodate the difference between the big and the small, and the fixed space is used as the virtual memory to speed up the access speed. The setting of virtual memory is best done after "disk defragmentation", so that virtual memory is not in a continuous, non-fragmented file space, which can work better. Eight, remove "wallpaper", "screen saver" and other fancy settings These settings take up system resources, but also seriously affect the windows startup sequence. To remove them, click the right mouse button on the blank space of the desktop and select “Properties> in the pop-up menu. In the pop-up dialog box, select “Background” and “Screensaver” “Wallpaper” and “Screensaver" set to “no" Nine, delete the autoexec.bat and config.sys system installation disk root directory under the autoexec.bat and config.sys these two files, windows already do not need them, you can safely delete them, this can speed up the windows startup speed. X. Streamlined *.ini files, especially the contents of system.ini and win.ini. Many drivers and font files are loaded in the [boot] and [386enh] sections of system.ini. In particular, the shell=explorer.exe in the [boot] field is a hidden loading place that the Trojan likes. The Trojans usually change the sentence like this: shell= explorer.exe file.exe, note the file here. Exe is a Trojan server program! With the subsequent loading and loading of the Trojan, not only the system security is threatened, but also the computer startup is much slower; the program that is loaded after the "run" and "load" of win.ini is not required to run every time. Temporarily clear, and then click Run when you want to use it later. In this way, the related files called by Windows will be much reduced, and the startup speed will naturally be much faster. Open the disk scan with a text editor to open msdos.sys, you will see the following: [options]bootmulti=1bootgui=1autoscan=1 If you do not want to run the disk scanner after abnormal shutdown, you can change the atuoscan=1 to autoscan =0, so the computer will start faster after an abnormal shutdown (because the scandisk is not running). 12. Let the boot information stay for the shortest time Open msdos.sys with a text editor and set the bootdelay in [options] to 0. Thirteen, reduce unnecessary font files Font files take up a lot of system resources, boot time is very slow, and take up a lot of hard disk space. So try to reduce unnecessary font files. However, if you delete the wrong font file, it will not be normal for Windows. Therefore, you can use the following method of "stealing the column" (you can achieve the installation of font files without taking up a lot of disk space): first open the font binder (such as f:\\zk), select all truetype font files, use the mouse Right click and drag them to the c:\\windows\\fonts binder. In the pop-up menu, select “Create shortcuts in the current location, so you can create shortcuts to the font files under the system font binder. It is. When you need to use these font files, just insert the font disc and remove it when you don't need it. Fourteen, delete the redundant dll file in the window operating system's system subdirectory there are many dll files, these files may be shared by many files, but some do not have a file to use it, that is to say these files are not Used, in order not to take up the hard disk space and improve the startup speed, you can delete it. Open the registry, expand to the hkey_local_machine\\software\\microsoft\\windows\\currentversion\\ shareddlls subkey, there are many dll files on the right, if the data is 0, you can determine that the dll file has no program sharing, you can delete it. Fifteen, "next door left channel" method, such as the use of system suspension, the current system state is saved after shutdown, the next time you boot, the system will directly enter the desktop before the last shutdown, with this method, the boot time can be the fastest It takes 4-5 seconds, but not all motherboard bios support it. It is also a little troublesome to set up.
