Glad you resolved it
Drivers for a system are generally available at one of two sites:
a. The manufacturer of the system if it is a "name" system (e.g., eMachines, Dell, HP, etc.).
b. The manufacturer of the motherboard in the system, if system is custom/self-built.
Installing drivers is pretty simple:
a. Remove/uninstall the current drivers. I suggest this because I believe that leaving damaged files in the system...often result in new drivers not functioning/installing properly.
b. Install the new set of drivers, following instructions for doing so which are at the website you downloaded the drivers from.
