Windows system must be aware of the three things before reinstalling

Now reinstalling the system is not a big deal, everyone will re-install, but whether it is installed system or reinstall the system encountered problems always, if It is troublesome to encounter problems in the process of loading, which requires you to be prepared before reinstalling. Many netizens' computers often encounter problems that cannot be solved. They often choose to reinstall the system. The reinstallation problem will also come from the street, so there are 3 points to know before reinstalling the system.

1 Formatting

If the system is infected with a virus, don't just format the C drive. The virus may be in another partition. Only the C drive is formatted and the system is reinstalled. The new system in the C drive is likely to be used by the hard drive again. The virus in the partition is infected, 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 is easy to get rid of it.

2, after reinstalling, first install the firewall and anti-virus software

After reinstalling the operating system and do not immediately connect the computer to the network, it is best to unplug the FTTB when reinstalling the system. Line! Because FTTB does not need to use dial-up software to automatically connect to the network, no anti-virus software protection. The newly installed system is very susceptible to viruses! This reinstalled system has been abandoned! So, reinstall the operating system Please install the firewall and anti-virus software first, then let the computer connect to the network. Once the computer is connected to the network, immediately upgrade the firewall and anti-virus software, download the latest virus database files, and make your newly installed operating system 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

3Is the various drivers installed? Is it suitable? The following mainly introduces two important drivers:

Graphics driver

After installing the graphics driver Adjust the display's refresh rate so that the display works at the default refresh rate of 60 Hz. 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 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.

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.

Is the hardware driver all installed?

Check if the hardware driver of the computer is all installed, or is it appropriate, right click on my computer — attribute — hardware & mdash; device manager, look at the computer Whether all the hardware is installed in place, if there is a problem with the device, there will be a yellow question mark or exclamation mark in front of the device.

Although the system is reinstalled, the reloading is the same as the initial installation of the system. There are a lot of problems in the system installation process. This requires us to prepare in advance, so before reinstalling Prepare everyone to have a look.
