The elite of the firewire can't open it.

If the computer has a network but can't open the webpage, it is probably a DNS cache problem or a virus.

The solution is as follows:

1. Clear DNS resolution cache.

Generally, the system will cache commonly used DNS addresses, which can speed up the computer's rapid access to the network. But sometimes these DNS addresses are abnormal for some reason, which will lead to the failure to open the web page normally, which will lead to the failure to open the web page. Understanding DNS cache can generally solve the problem.

The steps are as follows:

① Press and hold the shortcut key "Windows+R", enter "CMD" in the pop-up dialog box, and then press enter.

② Enter "ipconfig /displaydns" in the new command prompt window to view the dns address previously used by the system.

③ Then enter the command "ipconfig /flushdns". The main function of this command is to clear DNS resolution cache.

④ After successfully refreshing the DNS resolution cache, you can solve the problem by reopening the browser.

2. If the Trojan virus changes the settings of the computer, you can enter the safe mode to kill the wood virus and use the Trojan cleaning tool to clean it.

3. Input in operation: regsvr32 actxprxy.dll/REGSVR32 shdocvw.dll re-registered these two dll files and restarted the computer after the completion. These two files can not only solve the problem that IE can't open a new window, but also click the hyperlink with the mouse without any response. It can also solve other IE problems, such as incomplete display of web pages, no JAVA effect, inability to automatically jump to web pages, and opening some websites always prompts' Cannot display this page'.

If the above operation fails, you can format the backup data and reinstall the operating system.
