I'm not sure what you're describing with "BD 70G", eg: network device model, motherboard model, computer model, other? That's why we provide a Comment Box
with our request form.... so we don't have to attempt mind reading or consulting our crystal ball. Saves us lots of time and get's you a much quicker and more positive response. Along with that info, you should always say whether it's used in a desktop or laptop pc. Little details like that do make a difference because a driver made for a laptop will not work on a desktop and vice-versa.
HP/Compaq does not post drivers according to the motherboard model, they post them according to the pc model they came installed in. Go to the link below, type in your computer model #, then click the SEARCH button, then select your OS.
If none of the above works for you, consider using this program:
