BSOD reference (my website):
BSOD
The WinDbg one is the one that tells you how to run memory dump analysis'
Updating ASACPI.SYS is sorta strange. It depends on the make and model of your mobo, the OS that you're using (Windows 7 32 or 64 bit), and if the appropriate file is available for your system.
The 2005 version of the ASACPI.SYS file is the one that causes the most problems with Windows 7.
That being said, it's not 100% certain that it will cause BSOD's (I've got it on my Asus P6T Deluxe system and it isn't BSOD'ing on me (although it may be related to my issues with sleep/hibernation - but I'm too lazy to check it out).
The actual device that uses it is listed in Device Manager under System Devices...ATK0110 ACPI UTILITY
Interestingly, the
driver date there (on my system) is 2004
So, go to the Asus support website and download the appropriate driver from this list (it may be under any of the headings, so check them all. Most likely it's going to be under the Utilities heading.
First is the ATK0110 driver
Next is the Asus AISuite
Next is the Asus PCProbe
All of these will install a 2009 version of the ASACPI.sys file on your system.
