Issue with my Compaq takes me to desktop

I've noticed that hitting ctr alt and s simultaneously brings up a computer info screen and minimizes the game.

It's not an issue with GW, obviously, but I was hoping someone else had maybe found a way to disable these keystrokes. I'm still looking myself, so if I come up with a fix, I'll post it here.

Anybody have an answer? Usually, I can find this kind of stuff myself, but so far all I can find is that the keystroke combo is mainly used during boot to get into the bios. I still haven't found a way to disable it though.
