What should I do if my computer is extremely slow after reinstalling the system?

The response is slow. There are two possibilities:

1. The new system image is not good. Find the authentic image file and install it again.

2. The settings are not in place, including driver mismatch and other factors.

Slow booting is generally divided into three parts:

First, the BIOS has a long black screen time (more than five seconds) after booting. You can set the BIOS to factory defaults.

Find: Lood setup Defaults and press Enter to confirm. After saving (F10), restart to restore to the factory default state.

Second, turn off random startup items. The more random startup items are enabled, the more trouble there will be. No matter what program, you can wait until it is started before opening it.

The reason is that after these things are randomly started, they will never exit automatically. Not only do they occupy limited resources, they will also fight with each other!

① Start → Run → Enter: msconfig and press Enter to open [System Configuration Utility] → Startup Items → Disable useless random startup items.

② You can also use third-party software for optimization: 360 Security Guard → Optimize Acceleration → [Startup Items] → Select unnecessary stuff → Disable startup

③ If the computer has a printer or scanner installed Wait for the device, or if the USB hard drive is already connected during startup, you might as well try disconnecting them first to see if the startup speed changes. Generally speaking, because the USB interface is slow, the corresponding device will have a significant impact on the computer startup speed. Try to connect the USB device after startup.

④ Check if there is a CD in the CD-ROM drive? If you have a CD, the computer will read it when you turn it on.

⑤ Shared folders and printers will also slow down startup speed. Storing large files on the desktop can also slow down startup speed.

Third, entering the desktop after passing the Microsoft logo flag (four-color square flag) is obviously slow:

If the computer is connected to the LAN, the system will automatically obtain an IP through DHCP by default. address, but most companies' LANs do not have a DHCP server, so if the user sets it to "obtain an IP address automatically", the system will continue to search for a DHCP server in the network when it starts until it obtains an IP address or times out, which naturally affects At startup time, it is best for individual users to assign a fixed IP address to their computer.
