I am working on an ASUS G73SW and am performing a clean install of Windows 7 Pro 64bit. I installed the chipset driver's from ASUS' support site but I think there may be some issues since the USB 3.0 port isn't showing up at all. I believe the version from ASUS' site is old, and is recognized by the Intel Update Utility as being version 9. When I run the Intel Utility, it recommends going to the latest version (10) and it will download the software needed. I downloaded the software and installed it without any problem according to the installer. However, the Intel Utility shows it as failed and still shows version 9 as being installed. If I check the registry, it seems to show version 10 as being installed, so i'm not really sure what to believe.
Personally I think it didn't install correctly, or installed half the components and not all of them. Is there any way to tell? What else should I check? The 2.0 USB ports all work, but I don't see 3.0 listed in device manager anywhere like I do on other Windows 7 PCs.
Update - I added a screenshot of my device manager so you can see what i'm working with.
