Give you a correct answer. The architecture of AMD processor bulldozer series is not compatible with the corresponding motherboard BIOS under win7. You can upgrade the BIOS, but it's dangerous. You can also upgrade to win8. But many games are cracked without the recommended version of win8. Snake Girl -CEG software only has1m. Just run it at startup. In addition to the graphics card, I am equipped with wi-Fi just like you. After the n7 and win8 dual systems run Snake Girl -CEG, win7 runs normally, and the startup speed and running speed are the same as Fit.
