Language bar changes on it's own

The language bar randomly changes the language from us english to chinese for no particular reason, it also changes the keyboard input from US to multilingual canada, (which isn't that bad, you just lose out on most of your punctuation) has anyone else encountered this problem, I can change it back, it's just annoying when your typing and then you look at the screen and somewhere halfway through it you see that the language changed without any intention.
I can change it back but every couple days on the 3 computers I have purchased win7 for are having this issue, so I know it's not a hardware issue.

1. Did you make any changes prior to the issue?
2. Did you create a shortcut key to enable or disable the language?
Usually pressing the left Alt+Shift keys will switch the input language when multiple input languages are enabled.
