Can't find drivers for pc

hello,
I recently have installed windows 7 on my system
over the windows 8 that came with the machine because I got so sick of windows 8. I am now having issues with drivers, I can't find any for windows 7 because it came with 8 installed. I also cannot connect to the internet with Ethernet or wireless. model of my PC is HP envy dv7 7238nr, is there anything anyone can do to help me out or at least give me a little direction? any help is appreciated, thanks.
