Motherboard problem and driver problem...

I used drivercleaner to clean all my nvidia graphics card drivers, but it seems that it also cleaned some of my nvidia nforce4 drivers and nvidia lan drivers. I have an Epox 9Npa+Ultra mobo. Epox's crappy website doesn't have any drivers for it. Device manager says I have ethernet and it's working properly (but no internet), my PCI bridge device, pci memory controller and sm bus controller aren't installed. Should I just reinstall Nvidia's Nforce4 drivers on my computer again? Could I just wipe all the nvidia's drivers (driver cleaner) and reinstall nforce4 drivers (off nvidia's site) and be good to go? Will it still allow me to run my raid? If not that, what should I do?

I think if you just reinstall the nforce drivers and other drivers that nvidia uses. RAID will probably still work.
