So i did a factory reset and now there are 6 unknown devices with missing drivers. Thankfully they are all named. I tried googling the name of the drivers that I need but I have only managed to find one like that. Anyone happen to know where i can go to find drivers for these?

3D Video Controller (says i have to get an Intel driver first)
Network Controller
PCI Device
PCI Simple Communications Controller
SM bus Controller
Universal Serial Bus (USB) Controller
