I have WINDOWS 7 and MS Offiec 2007 running on my computer, but I fail to SEARCH any file from my computer HD written in *.doc or *.docx (MS word file) files. Moreover, while using the internet, after sometime the DIAGNOSE CONNECTION PROBLEM message is displayed.

How to solve this problem?

How are you searching your computer ?

SO it seems as if you have 2 issues here so I will reference each individually.

1. Searching within a Microsoft OS is not as simple as it use to be. With the growth of the platform; and files needed for it, as well as superfluous files added by you, the search parameters needed to be narrowed down (ie: indexing). It's hard and some what time consuming to do a canvas search anymore, specifically for a file format as popular as .doc or .docx. So yes, I would agree that knowing how you're searching for these is needed before assisting further.

2. When you get this prompt/popup concerning your connectivity, do you actually lose connectivity to whatever network you're currently on?
