Hello, I've got asus n53jn with Intel i3 M370. Problems began When i've install Windows 8.1 pro (original). My USB ports slowed to 5MB / s speed. Intel does't support my CPU so i can't install new drivers for windows 8.1 chipset. There is any solution of this problem? I don't want buying a new notebook.
Hello BlackCrow, I am sorry to hear you are having issues with your system.
From our side, the recomendacion we can provide you are to make sure you are running the latest drivers available and the latest BIOS version provided by Asus.
If the problem began after the installation of Windows 8.1, it could be because the chipset that comes on your system does not support Windows 8 or 8.1.
Please check the information provide by Asus. http://www.asus.com/Notebooks_Ultrabooks/N53Jn/specifications/
