when I try to open a word doc it opens then disappears.
Any suggestion on what will cause this?

Hello quanmay35,

Here are a few possibilities:

Fixing your Normal.dot file

Also it might help if you look at the Event Viewer for any Microsoft Word warnings/errors:
To discover the type of Errors the machine has encountered recently, use Event Viewer.

1. Go to Start - Run, type eventvwr.msc, then Press Enter.
2. When the Event Viewer opens, there will be two panes.
   The left pane is for event categories (Application, Security, and System).
   The right pane is for event messages (Information, Warning, and Error). (We want to find errors.)
3. Left-click the Application category in the left pane and check for any error messages in the right pane.
   You want to find the one(s) that occurred at the same time your system encountered the problem you have posted about.
4. Repeat the previous step for each category, or until you find an appropriate error to investigate.
5. Double-click the error message to bring up the information.
6. Click the third button on the right side of the information window (copies information)
7. Paste the information here

If all else fails, you can always do a repair install of Microsoft Word using your Office installation disk.

Regards,
