Dell Inspiron 2330 reverted back to win 7 - missing drivers  

I purchased a Dell Inspiron 2330 from a pawn shop - previous owner installed win 7 Ultimate 64-bit (replacing win 8). I got the activation code and downloaded a good copy of win 7 Ult 64-bit (from MS site) to do a fresh install to delete all his stuff !! Big mistake Cannot connect to internet. Multiple drivers out. Found a LAN driver to correct Ethernet driver but still unable to connect. Not very good at OS level diags (more of a "know just enough to be dangerous" type) :) Any help is appreciated. Have a laptop connected so can download and load via stick. I entered as much info as I could garner in the "System Specs" page of my profile. Thanks.

I have update the chipset and LAN. The yellow triangle was fixed on the Ethernet Controller, but I still cannot connect to internet thru my Ethernet connection. Network Controller is an unknown device; as is, PCI Device, PCI Simple Communications Controller and USB Controller. There is also and "Unknown Device" listed. This machine originally came with Win 8, but the previous owner downgraded to win 7 Ultimate 64-bit. I would put win 8 back on, but he removed the product activation sticker. Dell Support Rep told me it is on the motherboard !!!

I feel really stooopid right now. I unplugged and plugged back in the Ethernet cable. Computer now has internet access. duh! Thanks for all your assistance. I would not have needed this help if I had reset the Ethernet plug yesterday. Running WinUpdt now. Will probably run a couple of hours. lol
