0x000000A5 BSOD - ACPI Incompatibility...

[Kipper]

Hardware involved is:

2x256 PC2100 ECC Unregistered
1x512 PC2700 Non-Parity (backward compatible)

I am running these in an Asus A7V8X. Whenever I boot with the PNY in the computer, I get a BSOD as soon as I drop into Windows: 0x000000A5 - ACPI is incompatible with the BIOS...blah blah blah. I am able to boot perfectly fine with the two ECC sticks in this board (been running that way for two years). I'm able to boot with ONE 2100 ECC stick and the 512MB stick, or the 512MB stick alone, but unable to do so with both. The BIOS is recognizing the fact I have 1GB of memory, although it's hiccuped at times.

I've tried:

Reseating memory
Flashing BIOS to latest (1014)
Moving the sticks around in various slots

Everything yields the same results, until I pull out one of the ECC sticks. So I've essentially been able to run it with 768MB, but no dice for 1GB.

Any ideas?

I get that same message on older computers using after a Windows 2000 upgrade. Updating the BIOS fixes it. Since your motherboard was made in the last 4 years, you shouldn't have this problem.

Sounds obvious, but have you checked for a newer BIOS?

In OP...

"Flashing BIOS to latest (1014)"

That was the first thing I tried.

I also have an "ACPI not fully compatible ..." error when trying to boot into an IBM NetVista PC.

I am taking your advice to update the BIOS to the must current level. IBM's Tech Support page for my model states that there is a critical BIOS update that must be performed, so I suspect this will help.

To all who consult this thread for future use...

I updated the BIOS and my ACPI problem (blue screen of death) went away completely.

Furthermore, if you have an ACPI / APM problem with any PC, the first step I would recommend is to search out any possible BIOS updates and install them ASAP.
