GRUB and a hang implies it is choking very early indeed. The MBR is ok
because it said GRUB, but after that its a bit suspect and it seems its
not finding the the right blocks for GRUB (or something attached/changed
the BIOS config order - eg a USB bootable device - one box here fails
much the way you describe if I accidentally leave a USB key in it during
boot)

The fsck result is hopeful - but did you just get an immediate "clean"
return from ext3 or did you force a full check ? (-f option) ?

"It does complain that some of the points have not been mounted due to a
problem"

Actual exact message text is good, thats why error handlers don't
just all print "It broke"
