This D620 originally had XP Professional as its OS. About 1 1/2 months ago, I clean installed Windows 7 on it. It was not designed to handle Windows 7, and due to certain issues, I went back to XP. The only XP disk I have is XP Home Edition, which I clean installed this morning. I am now unable to connect to the internet; I was able to connect to the internet previously. In Device Manager, I have yellow question marks next to: Biometric Coprocessor, Data Interface, Data Interface [2 entries for the same title], Ethernet Controller, Network Controller, O2Micro CCID SC Reader, PCI Device, SM Bus Controller, Video Controller.
Suggestions / advice? Thanks.
