SYMPTOMS
A Microsoft Windows Server 2003-based or Microsoft Windows XP-based computer that is using a dual core or multiprocessor Advanced Micro Devices (AMD) processor that supports ACPI processor performance states (AMD PowerNow!) may stop responding. This problem is most likely to occur when you run a video-intensive program. However, this problem can occur whenever there is a processor performance state change.
CAUSE
This problem occurs because of a deadlock in the kernel power manager. This deadlock occurs because of a race condition that can occur when the processor performance state is changed on an AMD processor.

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.
