When playing computer games, you are most afraid of encountering failures, especially system failures. Both veterans and novices will scratch their heads. No, I encountered a problem: Whenever I surf the Internet for a period of time or switch folders, "Explorer.exe" crashes (Figure 1), and QQ is constantly disconnected, and even repairing and installing the operating system fails. No effect!

Quick Judgment
The Explorer.exe program is the system shell program, responsible for displaying the desktop , taskbar and other "tasks", and many applications also need the support of this process, and viruses, Trojans and other programs will also use this process to start or run. After this problem occurred, the author first upgraded the virus database of KV2006 to the latest version. After scanning and killing, no clues were found. It seems that this may be a pure system failure.
Ask for help in Microsoft's "Knowledge Base"
Next, the author searched for the keyword "Explorer.exe crash" and found that the discussions were all about viruses, Trojans and other programs. It seems that the only way to cause this problem is to check it in Microsoft's technical knowledge base.
As you can see from the error screen above, the system gave an "error signature" to the crash failure, which means the error type and error phenomenon description of the problem. For example, in this picture it will See: The error type is "InPageError" and the error characteristics are "P1:c0000C9c P2:00000003". Open the browser, enter /default.aspx?scid=fh; ZH-CN; KBHOWTO in the address bar, enter Microsoft's knowledge base search interface, enter "InPageError" in the search bar and press Enter to search (Figure 2) .

Since this problem also occurs when the author does not use the optical drive, I click on the second item directly. The page that opens details the symptoms, resolution, additional information, and scope of application. After carefully reading the contents in "More Information" and "Applicability", I found that the solution is indeed applicable to Windows XP systems, and the description of the error signature in "More Information" actually contains the information I got (such as Figure 3).

Tip: If you want to get the answer in the knowledge base quickly and accurately, get the error ID in the error message Or code is the main thing. In addition, you can log in to /search/?adv=1 to learn more about and use the knowledge base search.
Smoothly solved
Now I will repair it according to the solution in the knowledge base file: click "Start/Run" in turn, enter the "eventvwr" command in the "Run" dialog box and Press Enter, open the "Event Viewer", click "Application" on the left side of the window, click the "Source" column header on the right side to list all "Application Error" sources at the top of the list, and view the source as "Application Error" And the event with event ID 1005 found that there were indeed many error event prompts in the list (Figure 4).

Continue to double-click the event, and found the following content in the "Description" box:
Windows cannot access file C:\Documents and Settings\HZ\Local Settings\Temporary Internet Files\Content.IE5\index.dat, possibly due to one of the following reasons: the network connection, the disk the file is stored on, or the disk that is installed on this computer The storage drive is faulty; or the disk cannot be found. Windows has closed the program index.dat due to this error.
Program: index.dat File: C:\Documents and Settings\ZH\Local Settings\Temporary Internet Files\Content.IE5\index.dat
It turns out that the IE cache file appears Question, why does the knowledge base also prompt "Use the Chkdsk.exe program to check and repair the hard disk file system"? Could it be that there is also a problem with the hard disk? Therefore, the author clicked "Tools/Internet Options" in the IE browser, continued to click "Delete Files", checked "Delete all offline content" and clicked the "OK" button to clear the IE cache files, and finally in "My Computer" Right-click the C drive letter, switch to the "Tools" tab in "Properties", click the "Start Error Checking" button to check for errors in the disk, click the "Start Defragment" button to defragment the C drive, and then I discovered It turns out that there are so many fragments in my C drive (Figure 5)!

Tips: If you encounter certain files that cannot be deleted or the IE browser cannot be opened normally, it is recommended to create a new A user logs in to a new user account and then enters the relevant directory on the C drive to delete those stubborn files.
Editor's Note
From this point of view, the crash of Explorer.exe is not necessarily caused by viruses or Trojans. Too many disk fragments can also cause the system to fail to read files. An error occurred during the process, so it is very necessary to develop a good habit of regular defragmentation! Of course, we are able to solve the problem very well this time thanks to Microsoft's knowledge base. If you encounter various system problems in the future, you can also search in the knowledge base first, and maybe you can find help. Your quick way to solve problems will make you a system expert...
