Found the following at Microsoft Help and Support:

CAUSE
This behavior may occur if your computer's basic input/output system (BIOS) tries to write to one of the earlier ports by using an AML [Advanced Configuration and Power Interface (ACPI) Machine Language] System IO operation region. Your try may be blocked by Windows XP because accessing these ports by using this mechanism is deemed dangerous and can cause system instability. This feature is designed to improve the stability of your computer's operating system.
STATUS
This behavior is by design.

Contact the BIOS vendor for a possible BIOS update. For more information see the following Microsoft Web site:

Hmm... I'm not sure what to tell ya. I will read some more on this later today when I get some time. In the meantime maybe some others will have some info.

I actually had this exact issue when a stick of my RAM went bad. If you have multiple sticks I suggest you remove one and try it and then the other. If you do not have multiple sticks I suggest you try to find one to swap out as a test.

I have a few questions.

When did this error begin?
Which OS?
Did you add any new hardware?

perhaps not but given that ACPI == power management setup... I can't for the life of me see how RAM will affect this...

there is an error in accessing memory allocation... perhaps it is due to bios error (or requiring an upgrade)...

I am with enyo on this matter though.. consider flashing your bios and see if this fixes the problem....

Hehe, it's MS Windows, anything can go wrong at anytime, displaying any type of error message that could be or could not be related to the actual problem. I though this was taught in MS Windows 101. :rolleyes:
