Landlord, most of your situation is caused by system problems, which should be caused by the damage or loss of system files! In order to avoid the recurrence of this problem, resulting in hard disk problems, it is recommended to reinstall the system. Please provide detailed steps to install the system, each step as detailed as possible, hoping to help the landlord, and also point out the shortcomings! Thank you for installing xp. The steps are as follows: Press del to enter the bios interface when booting, and generally select the second item on the left. (Advanced BIOS function) After entering, look at the boot item, Frist Boot ... (Page Up and Page Down to select the CD, press f 10 to save, press esc to exit CMOSE, put the XP CD into the CD-ROM drive, restart the machine, and wait. . . Prompt to press any key to start from the CD ... Press several space bars immediately to enter the xp installation program (the screen has a blue background) and wait. . . Press F8 and select I agree. Press ESC, don't fix it. Press d, Enter, l, c, Enter, and then Enter. Format with FAT, enter, OK! Follow the prompts to install step by step. Finally, skip "Connect intalnat" and select "No, don't register for the time being". The driver and software are up to you. Remember to use GHOST to back up the system after installing the software! Note: 1, graphics card driver: After installing the graphics card driver, the refresh rate of the monitor was not adjusted, resulting in the monitor working at the default refresh rate of 60HZ. Long-term use will make people dizzy, sore eyes, decreased vision and so on. 6? 1? 6? 1 So, please don't forget to adjust the refresh rate of the monitor after installing the graphics driver. General 15 inch CRT is set to 800X600 75~85HZ, 1024X768 75~85HZ. When the display is adjusted above 75HZ, the eyes can hardly feel the display flashing. However, please do not adjust the refresh rate of the monitor to above 85HZ at will. If your monitor has average performance, it is easy to burn out the picture tube. Therefore, it is best to reinstall the monitor driver. If it is an LCD display, do not exceed 75HZ, because LCD and CRT have different image presentation methods. CRT does not refresh the image to make the display image, while LCD can move the image in the display only by changing the luminous particles, so the refresh rate has no effect on the LCD display and will not cause fatigue. 2. Sound card driver: Now many computers use integrated sound cards with AC97 specifications. However, the drivers of some motherboards are not in place, so users need to manually install the sound card drivers themselves. Many friends can't tell which one is on the CD, okay? 6? 1? 6? 1 Right-click on My Computer-Properties-Hardware-Device Manager-Audio, Video, Game Devices, and select Update Driver-From list or specified range. The selected range is optical drive: just specify the dirver—sound folder in the optical drive, which is more successful and correct than automatically searching for driver installation. 3. Check whether all the hardware drivers of the computer are installed, or whether they are installed correctly, OK? 6? 1? 6? 1? 6? 1? 6? 1 Right-click My Computer-Properties-Hardware-Device Manager to see if all the hardware of the computer is installed in place. If there is something wrong with the equipment, there will be a yellow question mark or exclamation mark in front of it. Please don't connect the computer to the network immediately after installing the operating system and hardware drivers! ! FTTB users had better unplug FTTB cable when reinstalling the system! Because FTTB can automatically connect the computer to the network without using dial-up software, this will make the newly installed system infected with the virus again! This reloading system will be useless! Therefore, please install firewall and antivirus software after reinstalling the operating system, and then connect the computer to the network. Once the computer is connected to the internet, immediately upgrade the firewall and antivirus software, download the latest virus library files, and protect your newly installed operating system. XP, 2000 users, please don't open IE browser without upgrading the anti-virus software, it will infect shock waves. Of course, you don't want the annoying system to automatically close the countdown dialog box as soon as the computer is installed. Hehe ~ 5. If the system is infected with a virus, it is best not to format only the C disk, because the virus may also exist in other partitions of the hard disk. If so, you only format drive C, and according to the installation of the operating system, the new system of drive C is likely to be infected by viruses in other partitions of the hard disk again, causing the system to crash again (I have encountered such a problem-_-#). So if you don't know what kind of virus your computer is, you'd better format it thoroughly to ensure the safety of the newly installed system. Of course, this is just my personal opinion. I won't do it unless I have to, because there will be some "important" files in anyone's computer ~ it's easy to make people feel distressed:) I work in IT, and computer maintenance is also part of my job. Let me tell you how I installed the popular XP operating system for your reference: 1. After the computer is turned on, press the DEL key to enter the computer CMOS settings. According to the BIOS of the motherboard, generally choose.
