This looks to be remarkably similar to an issue I'm pursuing.
I've just reformatted the disk, and installed a fresh copy of Windows XP
Home SP2. The PC still freezes (this has been an issue for quite some time).
There seems to be a regular pair of events in the System event log that
accompanies such a freeze:
Event Type: Error
Event Source: ACPI
Event ID: 5
Description:
AMLI: ACPI BIOS is attempting to write to an illegal IO port address
(0xcf8), which lies in the 0xcf8 - 0xcff protected address range. This could
lead to system instability. Please contact your vendor for technical
assistance.
The other is the corresponding 'read' event.
The corresponding link to Microsoft's site gives the following information:
*********************
Product: Windows Operating System
Event ID: 5
Source: ACPI
Version: 5.2
Symbolic Name: ACPI_ERR_AMLI_ILLEGAL_IO_WRITE_FATAL
Message: %2: ACPI BIOS is attempting to write to an illegal IO port address
(%3), which lies in the %4 protected range. This could lead to system
instability, etc.
Explanation
The system BIOS attempted to incorrectly access hardware resources
concurrently with the operating system. This type of access cannot be
synchronised and can cause system instability.
User Action
Contact the system vendor for an updated BIOS and follow the vendor's
instructions for installation.
*********************
I cannot seem to find a suitable BIOS update, but am awaiting a response
from the system vendor.
However, following a comment in another forum, I changed the Plug and Play
Operating System setting in the BIOS to No/False. This setting is recommended
in a Microsoft article (http://support.microsoft.com/default.aspx/kb/314068)
anyway. Following that, I was able to run the PC for a good couple of hours
as it downloaded and installed a large amount of updates from Microsoft
Update. It hasn't frozen since, but as that was only last night, I can't be
certain of success yet. However, prior to that, the PC was freezing so
frequently as to be unusable; it was freezing pretty much immediately on
trying to run updates from Microsoft Update, and also trying to install an
update from another site, so there has been a definite improvement.
I'll update these comments as I investigate further.

Just had a Windows XP Home system restore because of corruption. Ever since I.
got it home it keeps freezing. It freezes at least once an hour during any
operation, ie. internet, outlook email, documents, etc... It completely
freezes, no mouse, no keyboard, no ctrl+alt+del.....nothing! I have to shut
down the whole computer and then restart it manually......upon start-up each
time there is no scan disk.
What could be the problem?!?!?
Thanks for any help!!!
