SYMPTOMS
When you try to start your Windows 2000-based computer, the computer may stop responding, or &quot;hang,&quot; during the memory check phase of the startup process.



CAUSE
This problem occurs if both of the following conditions are true:
 * The amount of random access memory (RAM) that is installed on the computer exceeds the amount that is supported by the operating system.

-and-
 * Physical Address Extensions (PAE) is turned on in the Boot.ini file.

This problem only occurs with specific original equipment manufacturer (OEM) server configurations. If you run the kernel debugger, the system will appear to be stuck executing the MmInitializeMemoryLimits function. On some computers, the Windows 2000 operating system is set to only recognize 8 gigabytes (GB) of RAM. Memory more than this maximum setting is ignored. In the condition that is described in the &quot;Symptoms&quot; section of this article, the memory is not ignored, and this causes the computer to stop responding.
