SYMPTOMS

Consider the following scenario:
  • You use a computer that is running Windows Server 2003 or Windows XP Professional x64 Edition.
  • An NVIDIA USB controller is being used on the computer.
  • Devices connected to the USB bus draw excessive amounts of power (current) from the USB port on the computer.
In this scenario, you do not receive an overcurrent notification. For example, you do not receive a notification that the sum of the power requirements for the connected USB devices is more than the available power that the USB bus provides.

NoteIf you have many USB devices that are connected to the USB bus, one or more of these USB devices may not work. Also, if the overcurrent condition causes a USB port failure, the system may stop responding.

Technical support for x64-based versions of Microsoft Windows

If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
