I had a massive, heart-stopping IT scare today as when I was tidying my office an moving a pc, it stopped booting - I started asking arouind various forums/fora for help, considering moving the hard drive to another PC, and starting to think it was a hard drive failure.
HD connecting cable came loose when I moved the box to its cubby hole. After pushing it back in place, everythiong worked fine.

Thje most scary thing is that this is the PC I run the PAYE Bureau service and I still had some year-ends to do - I could face the thought of having to try to get the gateway access codes back from HMRC in tim e for the deadline for returns as I am hioldiay for a few days.
