I bought it in April. After using it for two months, there was a problem with the computer graphics card, and then it was good to restore the settings,Personally, the Win8.1 system works well, but the configuration of this machine is really not very powerful. Many large games can not be played, and the frame skipping card screen is something. But just watching a movie or going to a forum is still very good. There is no big problem with compatibility. Another is the appearance, but the blue color is out of stock,Finally, I had to choose a gray one, which was OK on the whole
