NVIDIA: Optimized nForce Driverpacks for Win7-10

Hi Fernando, i ask you to support me to make working my DFI LanParty UT NF3 250Gb with an ATI Sapphire 4650HD in Windows Vista / Windows 7 x86.
I’ve disabled from BIOS the AC97 on board, and it was working perfecly in Vista with the latest video driver (13.9 AMD Catalyst). But when i’ve tried to upgrade to Windows 7, it gave a BSOD after the end of installation at the first boot, so the installation had proceeded with a return to Vista and after this, also in Vista it doesnt work anymore (works only with Standard VGA driver)… why??? I would like to use Windows 7 resuming my old agp motherboard, upgrading it with the more recent overthere described ATI videocard. Please, can you help me?
Thank you,
Marcoland
