Hi all, my HP dv2419us notebook freezes completely when i watch any type of video with any type of player. My driver for the Nvidia Geforce go 6150 isn't the most recent one and I want to know how to update it. I already downloaded the newest version but whenever I try to install it and restart my computer, the driver didn't install. So I want to uninstall my current driver first and then install the new one, problem is, I don't know how to do that. Can someone tell me how to do this?
