[QUOTE="hughvane, post: 1837364, member: 56231"] Update - things have regressed to worse, there is no video signal coming from the Mini, so I cannot reset anything, nor can I boot into Safe mode, since there is no discernible boot activity. [The Mini is connected to a standby DVI monitor via an adaptor, and I'm informed repeatedly No Signal.] I don't think it's PRAM incidentally, nor SMC, as none of the symptoms of the problem align with their descriptions. What is notable however, is that the PSU is activated, the little white light at the front R corner shines intermittently (until the Mini shuts itself down), but the weirdest part is how the machine hisses at me with a low level 'woosh' sound, which I have tried to record with a camera on video setting. I have never encountered this before, and can only assume the noise is coming from the inboard speaker. What might it be/indicate? Further thoughts and/or advice please before I submit the Mini to an authorised repair centre (great timing, just before Christmas). [/QUOTE]
