The GPU of two identical graphics cards doesn't work

1. Starting from the CD: "start the recovery console"

set the CD startup
when starting up, press the Del key (repeatedly) in the first screen to enter the BIOS settings
for award's BIOS, select the second option of first boot device, press pagedown or pageup, or the plus minus sign to select until the CDROM option
appears, then press ESC, press F10 to save your changes and restart
for AMI BIOS, after entering the BIOS, press the right key to Item 4, find the option of first boot device, adjust to the CDROM, save the changes, exit and restart

insert the installation CD of Windows XP, after starting the computer, the system will automatically enter the Windows XP installation interface option, press the "R" key to select the second item "to use the" fault console "to repair the installation of Windows XP, press R" The system automatically logs in to the recovery console
it will automatically find and number the existing system and its installation directory. At this point, the prompt asks which system you need to repair. There is only one. If there are multiple, they will be displayed. Enter "1" and press enter

2. If we want to use the recovery console to repair the system, we should be familiar with the common commands in the console. After all, the recovery console repairs the system by executing commands from the command line. For those familiar with DOS commands, most DOS commands can be used in the recovery console, including attrib, CD, CHKDSK, CLS, del, dir, format, Ren, RD and so on. Their usage is similar to before. For the specific usage of the command, interested friends can view the instructions of various commands through the help command. For example, if you want to know how to use the expand command, you can enter "help expand" to see the detailed instructions. Although the above commands are similar to those in the past, some commands have been enhanced in the console. For example, RD command, whose original function is to delete a specified directory, has no command parameters, but adds two new parameters in the console: [/ S] to delete the directory tree, that is, to delete the directory and all subdirectories and files under the directory, which is equivalent to the deltree command in DOS[/ Q] When you delete a directory tree with the above parameter, the system will ask the user to confirm whether you really want to delete it. If you use the / Q parameter at the same time, that is, "rd / S / Q", there will be no confirmation prompt ring the deletion operation, which is equivalent to adding the / Y parameter after the deltree command. Another example is the format command, whose function is to format the specified drive to the specified file system. In the console, it adds a new parameter: [/ Fs], which can format the disk according to the specified file system type (fat, FAT32, NTFS). For example, "format D: FS: NTFS" command means to format disk D in NTFS format. If no file system is specified, the current file system will be maintained for formatting. After Windows XP is installed, if Windows 98 is re installed, the boot.ini file that contains the system multi boot menu will be destroyed and the boot menu will disappear. At this time, we do not need to re install the Windows XP operating system, as long as we use the system recovery console, we can easily make the multi boot menu reappear. First, enter the system recovery console, and then enter: bootcfg / list at the prompt. At this time, the existing entries in the boot list will be listed; Then enter bootcfg / scan, which will scan and display all available Windows installation files on all available disks; Executing "bootcfg / rebuild" will repeat the windows installation process and allow the user to choose which item to add to the Startup menu. Press y key to indicate "yes" option and prompt "input loading ID". We can input "Microsoft Windows XP Professional", enter and prompt "input OS loading option", and input: fastdetect. Continue to enter, exit and restart the computer, you can see the familiar multi boot menu. We can also use the command bootcfg / add to add items to the boot menu. The steps are similar to using the command bootcfg / rebuild. You can try it yourself. Recover important files of the system. When the system starts with command, it will prompt that NTLDR or ntdetect cannot be found. This happens when multiple systems are installed in the same partition, and the corresponding files in the system root directory are deleted by mistake. In fact, these two files can be found in the i386 directory of the Windows XP installation CD. With the help of the recovery console, we can easily them from the installation CD to the hard disk system to achieve the repair goal. First enter the console, and then enter "F: &# 92; i386\ Enter after the command "NTLDR". Press "Y" if you are prompted to override. Then enter F: &# 92; i386\ Ntdetect.com, and press "Y" if prompted. When finished, exit and restart the computer. You can now start normally. Tip: the command can only a single file and cannot use wildcards. In addition, when inputting the command, make sure that it is in the installation root directory of the system to be repaired, otherwise error prompts will appear. Use the expand command, which is suitable for extracting the files in the cab package. You can use wildcards to extract multiple files. Prompt at startup that a DLL file cannot be found. This kind of situation often occurs when we unload the unused software and accidentally delete the important files. Using the recovery console, we can extract the files from the compressed files for repair. Suppose we want to extract the DLL file from win. Cab. First, enter the console and enter: expand F: &# 92; i386\ Win.cab / D / F: *. DLL, view the DLL file contained in the win.cab package. Then enter expand F: &# 92; i386\ Win. Cab / F: *. DLL can all the DLL files in the compressed package to the root directory of the system. Tip: you can't add space before *. DLL. If you add space, you will make an error. Then them to the necessary directory, and the system will be repaired successfully after restart. Repair the boot sector of the system. The content of the boot sector of the system is damaged e to the invasion of virus. At this time, we often use anti-virus software to repair it. In fact, we can use the recovery console to repair it. From the CD-ROM boot to the console state, input the fix boot command, the program will automatically re write the correct boot sector content, and then restart to start normally. The command can also add a drive character parameter to write the boot sector content to the specified partition. Please refer to its help for detailed usage. To enable or disable services and hardware, sometimes we start from the idea of optimizing the PC, enabling some system services and hardware, but causing the operating system to crash. In this case, how to disable the enabled system services and hardware? At this time, we have to call out the recovery console. With its listsvc and disable commands, we can easily solve the above problems. From the CD to the console, enter listsvc. In this way, all the services and drivers on the system will be displayed in the form of a list, and their current use status and optional comments will be displayed. What we need to do now is to record the name of the service or driver; Then enter "disable disabled service name or driver". After entering, the previous service type and the modified new service type of the service will be displayed on the screen: "service"_ Disabled means disabled. Because the service type parameter is required to enable the service, we need to record the service type when using the disable command, that is, service_ DEMAND_ Start, in addition to service_ AUTO_ START、 SERVICE_ BOOT_ START、SERVICE_ SYSTEM_ Start, record these values, you can re enable the services correctly. If it is found that the problem still exists after a service or driver is disabled, it means that the problem does not occur above. At this time, we need to restart the service. The enabled command is enable, and the command format is "enable + service or driver name + service type". Hard disk partition formatting if you want to re format the hard disk space, but you can't understand a lot of English in fdisk, it is recommended that you use the recovery console to help you complete the work. Start to the console state, enter the Diskpart command and press enter. You can see a graphic partition interface in Chinese on the screen. Here, you can complete the partition work according to the prompts. After partition, you can use format to format the disk, just add the corresponding drive letter after the command.

3. The console program is usually executed with the command line
when you double-click, it is usually handled by Nautilus (Gnome) or Konqueror (KDE). You just need to set your file manager's action on this kind of executable file

it is recommended to use the command line

4. Use javaw command instead of Java command
the following are the differences. I don't know whether you want this effect or not:
both applications can run your program, and they are very similar, but there is an important difference, Java runs through the console, javaw is not
the console is almost written for plain text. For example, if you run javaw, all your printed status will not be printed. The same is true of the useful information you print in the program, as well as the error information
so, if you are choosing which one to use:
if it is based on plain text, use Java
if it is graphical but printed as plain text at any time, use Java
if you are checking for errors, use Java
if the program is purely graphical and you need to speed it up, use javaw.

5. 1. After the installation of Windows XP, if you still want to use the recovery console in the CD, you can put the Windows XP installation CD into the CD-ROM drive and start the system through the CD-ROM; Recovery console & quot; After the interface, press the R key in the keyboard, and then after logging in the necessary files, the recovery console window will appear
2. Install the recovery console to the hard disk
if the console is commonly used, you can install the console in the hard disk, Windows XP, put the installation CD into the CD-ROM drive, then open the command prompt window through "start all programs accessories command prompt", and press "CD X: &# 92; To install the recovery console, enter the i386 directory of the installation CD, and then type the "winnt32 / cmdcons" command. The program needs about 7MB of hard disk space. When running, a window will pop up and choose to install. It can also be installed in DOS environment by "WinNT / cmdcons" command You can install the recovery console program only after the normal installation< Second, use the recovery console to restart the computer; Start & quot; Select "Microsoft Windows XP recovery console" in the menu and enter to enter the command line window of the recovery console.

In recent years, the virus, here specifically refers to the worm virus

Stuxnet worm, ms10-061, when the worm enters the machine, set itself to boot automatically, release the driver file, and set the driver to service self boot. The driver is responsible for breaking through the limit of the number of TCP semi open connections in order to facilitate worm propagation through the network. The mobile drive (i.e. U-disk) of the infected system can spread itself through the U-disk. Through ms10-061 printer service Remote Code Execution Vulnerability, it spreads itself in LAN. And try to use some weak passwords to try to guess and obtain the host authority, endangering the security of the whole network. A back door is set up for the computer to continuously try to connect to the remote hacker server, collect user information, receive hacker instructions, and obtain and execute the hacker remote server Trojan horse, which brings serious security risks

panda burning incense is a bit long for me. Although I had the initial worm virus, I didn't parse the key code. I only found some variants that have changed 50 times from the network

panda burning incense will not damage the file, but this is OK
