Cannot install driver / drivers missing on new install win7 ultimate  

Hello, this is my first post on the forum, and I hope you can help me.
I have recently been given an HP 6465b probook. It had been dropped and the hard drive had failed. I installed a new hdd and got a copy of Windows 7 ultimate x64. The install went well until I discovered I couldn't connect to the Internet. There are at least 5 drivers missing.
They are for the SM Bus controller, Broadcom netxtreme gigabit ethernet controller, Broadcom netxtreme II network controller, two unknown devices. Now I think about there may be others as well.
I checked the system 32 / drivers folder and they are all there I think.
I tried to install the drivers in the usual way but windows says it cannot find them. I tried to install them from the windows disc. Again windows couldn't find them. I connected to my router via cable to try get cconnected that way but no luck. I have downloaded drivers to cd and installed from there, but I got an error code 10 device cannot start. In sysinfo it says driver not installed properly.
So I am at a loss as to what to try next. I hope the forum can assist with this.

Kind regards,....... Amazingmin (Dean)

Thanks for your help. I have got connection to Internet now, so getting the drivers has been a lot easier. Some will still not install, as Windows says it has the correct driver, but cannot install it as access is denied. I presume this means I have to be logged in as an administrator, or is it something else?

Hi, I have a custom built computer (GA-F2A85X-UP4 AMD A10-5800k) and had to reinstall windows. I was able to get all drivers from Gig website but I still cannot use them to update USB. I get an error message stating "windows has found the files for the drivers but it cannot install..." Any suggestions?

Thanks
