Hello everybody! As some of you know, the laptop Dell Inspiron 1721 runs slow with Windows Vista installed, so I want to upgrade/fresh install Windows 7. Unfortunately, I read on other forums that there is a problem with upgrading the Windows from Vista to 7 (it says that I need to update my ATI AHCI Compatible RAID Driver - even if I have the latest driver installed). I am curious. Has anybody managed to fresh install Windows 7 on a Inspiron 1721 without having any problems? I look forward to your answers!
