DAX Error - Computer Freeze When Clicked To Print Word Doc

I recently had my computer reformatted. Unfortunately, it still has some issues. The first problem that popped up was that my computer "froze" after I clicked to print a Word doc. The screen turned blue (of course, my first thought was I had the blue screen of death), and I couldn't do anything with it, other than a hard shut down. It came back up fine and worked "okay" the rest of the day, although somewhat sluggishly. The next day, I tried opening a Word doc. and the screen turned purple and again a freeze. Hard shut down again, and things worked "okay" the rest of the day.

The next day, I was opening something (can't remember now if it was a Word doc.), the screen blinked and turned the color of our home page, which is a sort of rust. I called our tech person, described the issues, and he suggested that I had a problem with Dreamweaver 8. I uninstalled it, as per his suggestions, and reinstalled it. Things seemed to be working fine, but I now get this error:

DAX Error
Error in TSafeMailItem - MAPI_E_CALL_FAILED. I'm wondering if it could be an issue with Spam Fighter, which I downloaded as per the tech guy's instructions. I didn't get the error message until after reinstalling DW, then checked my email. I do NOT open spam, and the sites I usually go to are safe. I'm not saying I couldn't have gone some where that wasn't, but AVG hasn't found any issues, nor has Spybot.
