I put together a computer with a P4 3.4GHz processor, WD SATA HD, Windows XP Pro, Radeon HD 3650 video card that came with a CD,Intel D945GTP MB with no installation CD. I went to Intel's site and downloaded files that I hoped were for the MB. I got sound and I'm not sure what else. Buy I coudl not connect to the internet. In the control panel in other devices there were four yellow question marks.
Ethernet Controller
PCI device
PCI Serial Port
USB Device
I am assuming I need the driver for the Ethernet Controller but don't know how to get it. If it is something else any help would be appreciated
