Could you recommend me what's the better procedure to install drivers on a clean installed Windows 7? Should I get the drivers and proprietary software included in the OEM's support site or just use DriverPack Solution to install them automatically? Thank you!
I strongly recommend those found in OEM site, definitely. Since they are especially tailored for your motherboard it don't matter if they are a bit outdated.
Definitely from OEM website. The DriverPack solutions can miss a couple like Intel Management Engine, HP 3D drive guard etc.
