SYMPTOMS

Consider the following scenario:

You are running a Windows XP-based computer that has an NVIDIA 680i motherboard installed.
You connect a keyboard to a USB port on the NVIDIA 680i motherboard.
You restart the computer.

In this scenario, the USB keyboard does not work. Additionally, a yellow exclamation mark (!) may appear next to the keyboard in Device Manager. If you disconnect and then reconnect the keyboard while Windows XP is running, the keyboard begins to work. However, this problem occurs again after you restart the computer.
