I'm trying to upgrade my pc to windows Vista. When installing from windows Xp, I get this error message:-
This computer is not compliant with the Advanced Configuration and Power Interface (ACPI) standard. Windows must be installed onto a computer that supports ACPI. Contact your computer manufacturer for a BIOS update or install Windows on an ACPI-compliant computer.
The Motherboard I am using is ECS P4VXASD2+. I have also updated the bios. In the bios settings I also made sure the ACPI is Enabled.
