Please try the following:
1. Update Spyder to 2.0.8
2. edit C:\python26\qt.conf and c:\Python26\Lib\site-packages\PyQt4\bin\qt.conf 
to contain:
[Paths]
Prefix = C:/Python26/Lib/site-packages/PyQt4
3. delete c:\Python26\Lib\site-packages\PyQt4\qt.conf

If the above fails please provide your PATH and python26 file listing.

I tried the method but failed. I attached my PATH and python26 file listing.

Thanks for data. 

Can you please resend the tree.txt with files as well as directories?

Also, please try to re-install PyQt4-4.8.3 without any other applications 
running.

I tried again to re-install PyQt4-4.8.3 without any other applications running, 
but failed.
I attached tree.zip with file list data.

I researched this problem several days and I found similar issues in 
http://www.qtcentre.org/threads/28768-Windows-7-DLL-Conflicts
As shown in this page, I doubt that you missed some qt dll version upgrade.

Finally, I solved the problem.

QtNetwork.pyd and QtNetwork.dll try to import other version of openssl dlls 
(ssleay32.dll, libeay32.dll) in different paths 
(C:\Python26\Lib\site-packages\PyQt4\bin and C:\Windows\System32).
I copied these dlls from C:\Python26\Lib\site-packages\PyQt4\bin to 
C:\Windows\System32 and now, can import QtNetwork.

PyQt 4.8.4 changed the internal dir structure (reverted actually) to a scheme 
which should solve the above issue.

In a nutshell, all Qt4 DLLs and executable are placed under the PyQt's root 
directory.

The issue should be solved in the PyQt 4.8.4 package (in 2.6.6.1).
