I get the feeling that I may regret writing this, but, touch wood, the PC
hasn't suddenly switched off since the thorough internal vacuuming. Whether
it was dirt on the mobo or the PSU, something has been dislodged, and it
seems OK again.

I've invested in a couple of fan filters. I reckon a lot of my troubles are
coming from the cute little houserabbit that lives in the corner of the
computer room. I found quite a lot of fine fur entwined around my intake
fans. Nice!

Fingers crossed!

Thanks for the responses...if it does reoccur, I shall replace the PSU.

Cheers

JW
