any help please i really need drivers
I checked the Samsung support site for your system, Support - Notebooks NP300E5E | Samsung Laptops and they do not have any Windows 8 or 8.1 drivers listed for your system. This would indicate that Samsung does not support Windows 8 on the system.
You can try the Windows 7 drivers Samsung ahs on the support site. Also, be sure to run Windows Update. Many driver updates may be available there.
If you want to try generic Intel drivers, here are 2 drivers that will work on your system.
Install the Chipset INF driver first. --> Intel® Download Center
You can also install the Intel HD Graphics driver. --> Intel® Download Center
