Several times now, my screen has suddenly gone black and instantly my t400 makes a loud, buzzing sound. The first time this happened was while I was playing Starcraft. I believe the other two occurences happened while watching videos.
I don't know if this is related to the video cards or if it's overheating, but I'd appreciate any ideas! I have updated my bios recently and yet the problem persists.

Sorry I'm only just now replying. I didn't realize anyone had replied. Anyway, I have an LED display. If my sound is muted, I do not hear the buzzing noise. Thanks for any help!
