Just a quick question about updating, im using windows 7 home premium on a hp dv7 3110ea, now i regulary update windows and hp using there update software, but on a more recent in depth energy performance scan i found at least 20 various software and driver downloads available to download from the hp site, now i have downloaded a few, bios update and graphics card, but am not sure to download the rest????????? i dont want to douple up on any drivers or downgrade any i already have by downloading these, i generally thought running the hp update would do these, but the bios wasnt'??????? But i also want everything upto date, any help would be appreciated, my computer is running 64bit ,Software & Driver Downloads HP Pavilion dv7-3110ea Entertainment Notebook PC - HP technical support (United Kingdom - English),
