It's a eMachine ET1641, Vista program was completely wiped off hard drive, loaded Windows Xp Pro, it is missing Ethernet Controller, PCI Device, SM BUS Contoller, Video Contoller (VGA Compatible) I went to the eMachine support site and they have downloads for SATA, (2)VGA, (2) TV Tuner, Chipset, Audio, LAN, Wireless LAN, Modem. I don't know where to put them or which ones to use. I have uploaded them onto a jumpdrive but when I try to install it says there is no driver for that device on the jumpdrive, yet when you look on the jumpdrive it is there and I can put them in a folder on the computer. I have tried that NLIte program, but I must need step by step instructions because it doesn't work when I put the Windows CD in to try to intergrate it..
