The drivers for Nvidia GE Force 8600 GT graphics cards are still missing from the shipped full issue of Windows 7 (as it was in the RC issue) !!! So it means if you try to install Windows 7 - everything works fine until the end of the installation, when you get a black screen - for ever !! Solution, use another graphics card, or use a VGA monitor , this will enable you to get Windows 7 up and running, then do Windows update - and guess what ? - one of the first updates that is shown ?? - correct Nvidia graphics driver, once installed the DVI interface works OK.
