5 points to reinstall Windows system

I have encountered many friends, or relatives, netizens, their own computer, when they encounter problems, they are free to find a system to install a CD to reinstall the system themselves, but then The problem that comes is coming. Let me take a look at the following points and install the system:

1, the graphics card driver: After the graphics card driver is installed, the refresh rate of the monitor is not adjusted, so that the monitor works at the default refresh rate of 60HZ. Long-term use can make people dizzy, eyes soar, vision loss, etc. So, please don't forget to adjust the display refresh rate after installing the graphics card driver, generally 15 inch CRT is adjusted to 800X600 75~85HZ, 17-inch CRT is 1024X76875~85HZ, 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 integrated sound card of the AC97 specification. 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 - Hardware - Device Manager - Sound, Video and Gaming Devices, select Update Driver - from the list or specified range, the selected range is the optical drive : You can 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 hardware driver of the computer is all installed, or whether it is installed correctly, you can right click on my computer - Properties - Hardware - Device Manager, see if all the hardware of the computer is installed in place, if If there is a problem with the device, there will be a yellow question mark or exclamation mark in front of the device.

4, after the operating system and hardware drivers are installed, 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 make the computer Automatically connect to the network, this will make the newly installed system re-infected 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 In the network, once the computer is connected to the network, immediately upgrade the firewall and anti-virus software, download the latest virus database files, so that your newly installed operating system can be protected. 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. Time-keeping dialog box~ Ha ha~

5, if the system is infected with a virus, it is best not to format the C drive, because the virus may also exist in other partitions of the hard disk, if so, you only format C drive, according to the installed operating system, the new system in the C drive is likely to be infected again by the virus in other partitions of the hard disk, causing the system to crash again (such a problem I have encountered -_-#). So if you are not sure which virus is in your computer, it is best to format it completely to ensure the security of the newly installed system. Of course, this is just my personal opinion. Whose computer will have some "important" files~ It’s easy to get rid of it.
