The BIOS in this system is not fully ACPI...

STOP: 0x000000DD


The BIOS has a bug or is out of date to work with this version of Windows. The issue relates to the configuration and power interface and plug-and-play abilities of the BIOS.

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

  Sample Screen  

A problem has been detected and Windows has been shut down to prevent damage to your computer.

The BIOS in this system is not fully ACPI compliant. Please contact your
system vendor for an updated BIOS.

Check with the PC manufacturer if you're using the latest BIOS or not. If not, update to the current version.

A few of the manufacture's download or support links for a motherboard/BIOS update:

    If the BIOS is current, it's possible bad BIOS parameters are causing the problem, especially if the memory or CPU settings are overclocked. The BIOS parameters are stored in CMOS memory. The best way to reset the BIOS parameters is to remove the CMOS battery. To do this:

    1. Unplug the PC, and open the case.
    2. Locate the battery on the motherboard - typically a silver coin cell.
    3. Remove the battery and note if the plus side is up or down, so you can reinstall it later the same way.
    4. Wait at least 1 minute and reinstall the battery.
    5. Attach power and power up. Typically a BIOS warning message will indicate CMOS was corrupted or changed and it may require you to go into the BIOS setup to set the time and date.
    6. Proceed to boot Windows and see if this fixes the issue.

    Some BIOSes have options to enable/disable caching and/or shadowing. If the options are available, disable caching and shadowing. Most newer (2005+) systems do not have these options. There are many BIOS makers and customized versions of the BIOS, so you may have to enter BIOS setup and look a bit to find these options. Typically you press a key like Esc, Del, F1, or F2 before Windows starts (almost right after you reboot) to enter BIOS setup. Consult your computer manual for details. The setup key can also be found in our BIOS access list.

        While BSoD fatal stop errors are identified by Microsoft Windows, they are often caused by non-Microsoft applications, drivers and hardware issues.
