Reinstallation system precautions

Many friends' computers are free to find someone to borrow a system installation CD and reinstall the system themselves, but the problem that comes with it comes. I will give you a brief Second, the installation system notes: 1, graphics card driver: After installing the graphics card driver did not adjust the display refresh rate, so that the display works at the default refresh rate of 60HZ. Long-term use can make people dizzy, eyes soar, vision loss, etc. · · So, please do not forget to adjust the display refresh rate after installing the graphics card driver, the general 15-inch CRT is adjusted to 800X600 75~85HZ, 17 inches The CRT is 1024X768 75~85HZ. When the display is adjusted to above 75HZ, the eyes are almost unaware that the display is flickering. However, please do not arbitrarily adjust the display refresh rate to above 85HZ, if your monitor performance is normal, it is easy to burn the picture tube. Therefore, it is best to install the monitor driver again. If it is an LCD display, do not exceed 75HZ. Because the LCD and CRT are imaged differently, the CRT does not refresh the picture to make the display appear, and the LCD can change the illuminating particles to make the picture in the display move. The refresh rate has no effect on the LCD display, and it will not cause fatigue. 2, Sound card driver: Many computers now use the AC97-compliant integrated sound card. However, some motherboard drivers do not work well enough, and users need to manually install the sound card driver. Many friends don't know which one to install on the CD. You can right click on My Computer — Properties & mdash; Hardware & mdash; Device Manager & mdash; Sound, Video & Gaming Devices, Select Update Driver & mdash; From List or Specified Range, The range of choice is the CD-ROM drive: then specify the dirver—sound folder on the CD, which is higher than the success rate and correctness of the automatic search driver installation. 3, check whether the computer's hardware driver is all installed, or whether it is installed correctly, you can right click on my computer & mdash; properties & mdash; hardware & mdash; device manager, look at the computer's hardware is all installed in place, if the device has problems If there is a yellow question mark or exclamation point in front of the device. 4. After installing the operating system and hardware driver, please do not let the computer connect to the network immediately! FTTB users should be able to unplug the FTTB cable when reinstalling the system! Because FTTB does not need dial-up software to allow the computer to automatically connect to the network. This will cause the newly installed system to be infected again with the virus! This reinstalled system will be abandoned! So, after reinstalling the operating system, please install the firewall and anti-virus software, then let the computer connect to the network, once the computer is connected When you get to the network, you can upgrade your firewall and anti-virus software and download the latest virus database files to protect your newly installed operating system. XP, 2000 users, please do not open the IE browser when the anti-virus software is not upgraded, this will infect both the shock wave and the shock wave. You certainly don't want the computer to just install the system and the boring system automatically shuts down. Timekeeping dialog box
