The hard disk indicator light is on, that means the computer system is reading the file again. . . It is recommended that you remove the virus in the sand. Under normal circumstances, the hard disk indicator light will not stay on and will flash during the reading process. The red light flashes not because the CPU is busy, but because the hard disk is flashing due to excessive reading and writing volume.

The red light is the hard disk working light

Optimize system speed

A few tricks to adjust the computer to perfection

1. There is also knowledge in booting the system

Every time you boot the system, is the startup process as slow as a snail? ? Will the system suddenly slow down every time I start a large program such as QQ? After using the computer for a period of time, the hard disk space is slowly being eaten up? Do you just want to collect the highlights of the wonderful music movies downloaded from the Internet or use them as signatures for personalized forums? This special topic will guide you step by step to solve these thorny problems...

Part One: Boot Boot Turns out to be knowledgeable

When you turn on your computer every morning, do you feel that your machine is always A beat slower than others? In fact, we can completely optimize the computer and speed it up completely without spending a penny!

1. Boot from the hard disk first

Many people ignore the startup sequence of the devices in the computer. Many people will boot from the optical drive by default, so that when starting Read the optical drive. If there is a disc in the optical drive, it will delay your boot. Even if there is no optical disc, the optical drive will be read when the system starts, which is not good for the life of the optical drive. Therefore, it is necessary for us to turn it off.

Press the Del key to enter the BIOS setup program, select the BIOS Features Setup menu, and then press the Enter key to enter the parameter setting option interface. Find and select the option Boot Sequence in this interface, and then press Page Down key or Page Up key, select CDROM, C, A to set the system to boot from the C drive first. Finally, press the Esc key to return to the root menu and select the save menu or directly press the F10 key to save the settings.

If you are using the Phoneix BIOS, press the F2 key when booting. After entering the BIOS settings, select the Boot option, then find the HardDrive item, and press the "+" key continuously to make it Adjust it to the top to ensure that the machine starts from the hard disk first.

2. Enable Quick Boot

Most computer BIOSes have a Quick Boot item. Under "Advanced BIOS Features (BIOS Advanced Options)", set it to Enable, so The BIOS does not detect the hardware every time it is started, which can greatly speed up system startup.

3. Shield unnecessary devices

Although parallel ports and serial ports are no longer popular, many motherboards still have these interfaces. At this time, we can completely block it in the BIOS, which can also speed up the startup of the system. Enter the BIOS, then select the "PNP, PCI&ONBOARD I/O" item, select Onboard Serial Port1 under it, press the PageUp or PageDown key, set it to Disable (disabled) state to turn off the serial port, press the F10 key , save the changes and restart the system. Of course, you can also use this method to lock IDE2, parallel port, USB and floppy drives, etc. This will prevent Windows from loading their drivers, which will naturally make them much faster.

4. Disable unnecessary hardware in Windows

For hardware that is not used on the machine, you do not need to let Windows load their drivers. You can open the "Control Panel" and double-click "System" icon, then click the "Hardware" tab, then click the "Device Manager" button to open "Device Manager", right-click the corresponding device, select "Properties", and then click "Device" in the window that opens. Usage" drop-down list box, select "Do not use this device (disable)", click the "OK" button twice to confirm the change

5. Reinstall the hardware

If your Multiple pieces of hardware are installed on the computer, but identifying them is no longer useful. Uninstalling one by one is not a wise move, because most people don't know where these drives are scattered on the hard disk, and it is impossible to clean them. At this time, we can remove all unused hardware, insert the Windows installation CD into the optical drive, open the SUPPORT\TOOLS folder on the CD, double-click the DEPLOY.CAB file, and extract all the files in it to a folder (such as d:\Sysprep), double-click the sysprep.exe file, and press the "OK" button to accept the warning message. And select the "Do not reset activation grace period", "Use minimal installation" and "Detect non-Plug and Play hardware" checkboxes. Press the "Re-seal" button and the machine will automatically shut down. After restarting the computer, Windows XP will ask us to accept the agreement, enter the serial number, and specify the system administrator and password. At the same time, it will re-detect the hardware and reinstall the driver. Because Windows re-detects and installs the driver, the hardware in the system is "clean" and there are no more redundant drivers, so the system will naturally run much faster.

6. Disable unnecessary services

Most people now use Windows 2000/XP systems, but there are more than 90 services, and 30 are enabled by default! In fact, only 6 is enough, disabling all "unnecessary" services will save 12-70MB of memory and make our computer faster.

Press Win+R, then services.msc and press Enter to bring up the system service management window. At this time, you can see the services in the system. Each name is followed by a description. Double-click any A service will pop up its properties window, as shown in Figure 3. If you feel that this service does not have much effect, you can click the "Stop" button and click the "Start" button to start the service. After adjusting the opening status of the service, restart the system to take effect.

Of course, it is not easy to remember the purpose of these services. Sometimes disabling a service that cannot be disabled will cause you a lot of trouble. A better approach is to start from a standalone machine that is connected but not LAN-wise, ALL uses the most aggressive optimization discussed on this site. Standard among them is more in line with the optimization solution recommended in this article. This script will change the running status of Security Accounts Manager, TCP/IP NetBIOS Helper and Windows Management Instrumentation to "manual". If you are not satisfied with the modified effect, you can choose Restore to restore the previous settings. Except that Netbios cannot be turned off, the automation of this script is very good. Since the script uses sc.exe to start and terminate the service, if there is no sc.exe on your machine (if you use Windows 2000), you will be automatically prompted to download it. Just press the Y key continuously in the DOS window.

7. Disable automatically running programs

If you start the computer every time, it always feels very slow. After the startup is completed, you will find that the tray area in the lower right corner always displays some icons one by one. That means you have too many automatically launched programs. Removing them can also speed up startup, and more importantly, remove some hidden Trojans!

First download the software from /files/StartupCPL.zip, then open it with WinRAR, and then double-click StartupCPL.exe to complete the installation.

Then open the "Control Panel" and double-click the Startup item. In the dialog box that opens, you can easily manage the startup items in the "Startup" folder and the registry. For example, right-click on the blank space to create a new startup item, and right Click on an existing startup item to edit, delete, disable, and run it immediately.
