I have a Dell XPS One A2420 with the Nvidia GeForce 9600M GT video card. I have been trying to upgrade to Windows 7 Ultimate 64 bit. I cannot find a 64 bit driver
for the 9600M GT that will work on this machine. In addition, the driver update from Microsoft will not work both in 32 bit and 64 bit. I have contacted Dell numerous times about this. Just before buying Windows 7, I talked to a Dell rep and he assured me that all the 64 bit drivers
, including the 9600M GT 64 bit, would be available for Windows 7 for this machine. To date no drivers on there drivers download page. All you folks out there that have this machine need to start calling Dell and put the pressure on them to correct this. I have also noticed that the XPS One is no longer being sold on there Web site except for refurbished models.
