Win2000 system can not open the web page solution

             A computer with win2000 operating system installed, fault performance: can log in to the home page of each website, but can not be displayed when entering the next level of content page, can not open the content page, some of the website home page can not be opened; at the same time, found that can not be copied, pasted Operation.
Open the home page, the major websites that can log in display the latest news, confirm that the IE browser is not the home page saved offline, indicating that the network is normal and the network works normally. Check the network settings, except the network ID is gray, the rest is normal.
I suspected the network virus, checked with the latest version of anti-virus software, did not find the virus and Trojan, and did not find malicious programs. Eliminate the impact of the virus on the system. Press F8 to enter the safe mode, and find that the copy and paste function is valid. The safe mode is a clean system without any driver and application. It indicates that the copying and pasting function is invalid because it is caused by adding a driver or an application.
The scope of the problem has been reduced, but there are too many programs for normal startup, and it is difficult to check the program one by one.
Restart the security mode with the network. After entering the desktop, it is found that copying and pasting is invalid. In this mode, the network failure phenomenon during normal startup also occurs. It seems that the problem lies in the network function. The security mode with network only cuts the network card driver. Is there a problem with the network card driver? The network card driver also affects the copy and paste function?
Enter the device manager. , select the NIC right button to uninstall the NIC driver. Restart normal access to the operating system, the system finds new hardware, reinstalls the network card driver, the network connection is normal, the DHCP server automatically assigns an IP address, pings the computer on the LAN, and connects normally; open IE browser, browse the major Website content, normal; check copy and paste function, normal, troubleshooting.
