Lock up Issues (I FAIL at installation~!)

[Kala]

 I bought Bon Voyage at the beginning of last week.  When the key screen popped up, my keyboard locked up.  Yesterday, I exchanged my copy of BV with the hope of actually installing the game.  When I tried to install Bon Voyage this morning, my keyboard locked up at the code screen.  I thought a clean install would solve the problem, but when I put in the Sims 2 DVD, my keyboard locked up for the third time today.  What is going on with my computer and how can I fix it?

Update: I told my brother about my problems and he thought there might be an issue with my DVD drive.  He hocked up his extra combo drive to my computer and the same stuff is happening.  I don't see any characters pop up when I type in the code box.

I believe a program I tried to install between Seasons and Bon Voyage borked my ability to type in the registration box of my Sims 2 game.  Someone else is going to reinstall windows altogether.
