When I insert anything in Word, no matter a clip, an equation, or chart, I
can only see an empty bordered box. I have to double click the box to review
what I typed in. I can preview it or print it out, but just can not read it
directly from word. In addition, I also find the Object under the Format menu
and Link under the Edit menu were in grey (turned off). I guess probably
there are some interrelationship between all of the malfunctions. Please
assist me to solve this issue.

A few things to try:
1. In Word, if you're working in Normal view, then switch to
Print Layout view (View | Print Layout), because objects that are
formatted as "float over text" (Word 97) or as something other
than "inline with text" (Word 2000, 2002, and 2003) are not
visible in Normal view.
2. In Word, click on Tools | Options | View tab | check the
"Drawings" box and uncheck the "Picture placeholders" box | Print
tab | check the "Drawing objects" box | OK.
3. If neither of the previous suggestions fixes the problem,
then try reducing the hardware acceleration setting in Start |
Control Panel | Display | Settings | Advanced | Troubleshooting.
If this fixes the problem, then you might want to check the
website of the manufacturer of your video card/graphics adapter
to see if there is an updated driver available.
