Remember: You download drivers for the motherboard components that surround it. Focus your search on your laptop brand and the integrated Intel HD Graphics. After a clean driver installation, your aging Pentium system will run Windows 8.1 smoothly, proving that older hardware still has life left.
Websites promoting “automatic driver updaters” for the B960 are often scams or malware vectors. Avoid any .exe from driver-haven.com or similar. These programs rarely have legitimate Sandy Bridge drivers.
