My kids pc keeps rebooting evertime the desktop appears I managed to boot on safe mode and do a virus/malware scan and it's clean,next step was to go to event log and got this entry around the time it reboots:

Event Type: Error
Event Source: ACPI
Event Category: None
Event ID: 5
Date: 12/06/2006
Time: 20:04:02
User: N/A

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 system vendor for technical assistance.

If you can boot into safe mode, do so...then go to your device the "computer" tab, you'll see acpi compliant blah on the driver tab...then select the "roll back" driver option....when you get to the list of devices, select "standard PC"...

this will,of course, take away all of your cool power saving features...but I've tried it on two XP systems that were experiencing random hard lockups, and once I changed from ACPI compliant.... to Standard PC in the device manager...the machines never locked up again for a memory read error...

under "roll back driver option" there are no drivers to roll back!!!
