my computer is HP Pavilion 14-n219tx and recently i updated my sound driver by downloading a driver from this site and since then my sound produced is worst and the key light which should be illuminating amber will not illuminate since then
and can i have someone to guide me on intel graphic. i think i need to reinstal the driver as when i try to open graphic properties by right clicking on the desktop, it shows ' GfxUIEx is not working ' . i cant find a solution. thank you very much.my intel graphic card is Intel(R) HD Graphics Family. version 9.18.10.3224
