It makes this buzzing noise, sort of a "vuh vuh". It only does this for game discs (no noise for a normal DVDs or when there's no disc). For games I'm running only from the disc it only makes the noise when I turn off the system while the disc is running. For games I have installed it makes the noise just as it begins booting and just as it ends.
It started this all of a sudden last night, so I'm a little worried. Does anyone have any advice?
