You are in luck it seems like HP offers the drivers for your laptop for free they are all their. I would link you to the exact page but for some reason it does not seem to work. Go to google and type in hp support then go to software and drivers section. Where it says enter model number type in g71-449wm and your laptop will show up along with all the drivers. Go down to utility tools and select HP USB Recovery Flash Disk Utility download it to a usb flash drive and reboot your computer again with flash drive plugged in with Utility on it.
