EDIT: Only one problem now. In device manager I have a "NVIDIA nForce Networking Controller - Packet Scheduler Miniport" that I want to uninstall. This device existed on my old motherboard, and my current motherboard has the RTL8111C chip. Why it tell me "Failed to uninstall the device. The device may be required to boot up the computer"??? Currently, I simply have it disabled. I would really appreciate anyone's help!
