All your logs look clean.
Try this. Go go Start->Run and type in
sfc /scannow and hit OK. See if it will find any missing/corrupted system files.
If that doesn't fix the problem:
Let's try registering Internet Explorer's DLL files. Go to Start->Run and copy and paste the following into the Run box and hit OK (go to Start->Run again for each one):
regsvr32 Shdocvw.dll
regsvr32 Shell32.dll
regsvr32 Oleaut32.dll
regsvr32 Actxprxy.dll
regsvr32 Mshtml.dll
regsvr32 Urlmon.dll
If that also fails:
Download WinsockFix
