Been searching for three days with no luck. Help me find drivers.

I have an early 2006 Imac core duo 2.0ghz.
I put windows 7 32 bit on it and I could really use help finding drivers. Ive searched everywhere with no luck. The bootcamp 4.0 drivers say they dont work on my system and manually installing dont help either.
The biggest thing I need is a sound card driver that supports the internal speaker. Externals work but the internal one does not.
A proper video card driver would be nice too.

Welcome to Windirvers Kavey. The best thing to do would be to download something like Hardwareinfo and run to find the maufacture of the hardware
you need drivers for then go to their site to download the proper driver. Also did you check the compatability list to make sure your model can have Windows 7 installed? Google search showed that even some of the later 2006 Imacs were not.
