Everytime I shutdown, and it's apparently after all of the running programs\nhave been stopped because the screen is dark and it's a split second before\nthe power goes off, I hear a loud noise through the speakers. It does indeed\nsound a bit like too many beans. I can not find the source, and I'm\nbeginning\nto think it may even result from a bios problem. It does it even with the\nsound Muted. Anyone with this board, Rev 1, have this problem? It's\nsomething new, I've had lots of successful formats and reinstalls before\nwithout this problem, but now it's there even after a fresh installation.
