You will need to go to the website for the motherboard manufacturer and download the updated drivers for that motherboard. This is common with all the changes that windows goes through in a life cycle.
Hi meangmoeurn, what makes you think your bios is not ACPI complaint? Enter your bios & disable ACPI. The reason for this is windows must be fully updated. One windows has been fully updated you can turn on ACPI. Its a software issue. Read through this Microsoft link; http://support.microsoft.com/kb/314088
Hey there rcrozier, your solution is to disable ACPI in the BIOS. To do so, follow these steps. 1/ When set up is loading, a blue screen will appear asking if you have RAID devices, indicating pressing F6. Instead press and hold F7. This should prevent ACPI from installing. Alternately at the blue screen mentioned above, press F5 and hold. It should advance eventually to a new screen prompting you to press F2. Keep holding F5. It will give you another screen telling you it cannot recognize your pc type. It gives you two choices: standard pc or other. Choose standard pc. resulting in ACPI not being installed. Unfortunately the other result of this ACPI not being installed is that your power management will be reduced. Overclocking is not advised. Hope this helps. Good Luck!
Look in your bios & see if you can disable the ACPI, (which you should be able too do. Finish installing your OS. Than update the OS. After completing all updates re-enter your bios & enable the ACPI. You should not get that error message after re-start.
Boards that support ACPI will get this error during a fresh install untill they get windows updated. All OS's
Post back if this did not help! It worked for me.
try disabling the power saving features at the BIOS startup screen. this is an ACPI (advanced configuration power interface) error. I think that Windows does not like the BIOS settings so it just errors out.
