G'day Dave, thanks for the great news!

I'll try to explain in detail what occurs. The grating is only a short, sharp sound, lasting for about a second, maybe less. It only ever occurs during startup, and not at all after that.

It grates twice in close succession after the bios screen has gone, just as the blue welcome screen appears. The welcome screen hangs for about 10 seconds before my user account appears. When I click on my user name, it grates twice again before the desktop appears. Once the desktop appears, there is no further grating.

That is the best I can describe it from memory. There may possibly be an extra 'grate' in there somewhere during the startup process. Thanks again.
