I was upgrade my home PC from existing 512kb to 2k since early Feb. Today I failed to open my pc and message shown the BIOS in the system is not fully ACPI compliant.
Anyone can give me your advise and what should I do for next.
Thank you very much
You might just check your BIOS settings and see if ACPI is disabled, it is required for 64 bit Operating systems. Maybe the battery that keeps your bios settings has died and you went back to default BIOS settings.
