So I told a friend of mine I could easily downgrade her Satellite C75D to Windows 7. No issue, right? Most drivers should be available through the manufacturer, and I've never had an issue downgrading before. I was so wrong, it isn't even funny. I've managed to install everything but the USB 3.0 and the Graphics driver. Surprisingly it states that the SM Bus Controller is installed for some reason. I've sat here trying every version of CCC I can imagine, up to the beta 13.8, which stated that it had support for the HD8330 that is integrated into the APU. Nope... no luck. I've got resolution up to 1600x900, but no Windows Aero. Device Manager lists the display as a Standard VGA graphics adapter. I've tried pointing Windows to 64 bit .inf files... nothing... I've tried pointing it to the CCC 13.8 Driver installation directory... nothing. I'm not usually one to ask for help, but I'm hoping somebody has run into this issue before. I know the APU for this unit is brand spanking new, but you'd imagine if it can support WDDM for Windows 8, why can't it support it for Windows 7? Any Ideas? EDIT: It's an A4-5000 with integrated Radeon HD8330 Graphics.
