Summary: MB was DOA ! PCrush did a cheerful RMA ! Will buy from this seller again. Will recommend to others. Although MB was DOA, I did like the way slots were arranged in a very logical and thoughtful configuration. Also, components seemed to install and fit more easily than other brands of MB I have used in past. Now I see why all the years of praise I have read about GigaByte boards. This is the first GigaByte board I have ever 'attempted' to use. Hope this helps.
Summary: So, I decided to update my BIOS to the latest version just to be up to date. Flashed it from Windows with @BIOS tool, recommended by Gigabyte. Everything seemed to go well, and it said it needed a reboot to complete. Pressed reboot. Windows immediately BSOD'd then went into Startup Recovery, which did nothing helpful. Then the screen went completely blank, computer shut off.
Summary: Looked long and hard for well-rounded Gigabyte MB to pair with discounted Intel Dual-Core chip. Only performance-related issue is the Intel Graphics adapter. Would have preferred Nvidia graphics for better color saturation and resolution. Very easy setup Windows 7 Pro.
