Microsoft Ergonomic Keyboard 4000 malfunctioning, typing random letters/numbers, etc.? - microsoft ergonomic keyboard function lock button stuck

In my work I have this keyboard from Microsoft for about 3-4 months, which initially seemed to work well. While we changed as a person my computer to another computer and now (I work with a new driver?) Asus. I'm not sure whether he is guilty, but the problem seems to be every time I start a new team.

He manages to letters and numbers at random, while I will open a sentence, the new window of Firefox add writing (there is a hotkey for this in the keyboard) and usually only makes me crazy! There seems no sense and reason to be how to stop it at random times and then only for some reason. Here is an example of what makes both type I:

"omg i wa7nt to 7 break this team stUP3id"

Sometimes it goes for weeks without it, sometimes it goes away, and as every day. Can someone tell me what the hell happened or how to fix it?
