...it's another. Having got Windows 7 64 bit up and running on the laptop and very happy with it so far, very stable and battery performance seems significantly improved, I went in to my desktop machine to see what I had by way of HDD setup as I have bought a new Samsung Spinpoint F3 1Tb drive to go in it and bump one of the existing ones upstairs to my daughter's machine. Haven't quite worked out how I'm going to organise this as I have a lot of data on both the existing ones and want to transfer some of it to the new F3 before doing anything else, there are two spare SATA ports on the motherboard there is no space to properly mount a third HDD. When I get in there I find that the fan on the Nvidia 6800 graphics card is knackered and whilst I don't play graphic intensive games on the machine, sooner or later it will cook itself. So that will be another £40 or so to replace it.
