Thanks :)

The motherboard was still under 30 day warranty, so it was replaced.
On boot "GRUB" appeared just once, but it wasn't the grub shell as
there was input from the keyboard which was accepted (?).

I did a clean install :(

Hi again Thufir!

If 'e' happened to be the first character you hit (after escape) then
you were in edit mode.

Still, I love a fresh install.

The history of the box leaves me a bit concerned.

1. Check out the loading of the power supply.  Basically, you look
through all the technical specifications for how much power (or amps)
are used and add them all up and see if the Power Supply is rated to
handle all of that.

2. Make sure the fans work and are turning in the right direction.

3. See that the box can "breath", that you are not blocking air inlets
or outlets.  It could get a bit hot in there.

4. Watch the CPU temperature.

I always simply wonder why things blow up.  Not nice to see again!

Have Fun!

Tod
