Critical Error from Audio Device

[Dknight007]

I built my comp a couple weeks ago and it endured the stress tests. But starting from yesterday, while I was playing WC3 online with my friend, my pc suddenly reboot itself, and I get this error, which microsoft says it has something to do with my audio devices. Here are the files related to the error as reported by microsoft
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\WERbde6.dir00\Mini122708-01.dmp
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\WERbde6.dir00\sysdata.xml
Today, it rebooted again after a few hours of online gaming (using vent and a Logitech mic, and same game too... for some odd reason). I look into my sound devices and this is what I have
ATI Function Driver for HD Audoi- ATI A401
Audio Codecs
Legacy Audio Drivers
Legacy Video Capture Devices
Media Control Devices
Realtek HD Audio
USB Audio Device
Video Codecs

Both times when this happens I was using Realtek HD Audio. I'm not sure what is going on... I have the latest drivers for audio, and everything seems fine. Could this be due to some other hardware/software. Right now I'm thinking of software conflict btw ATI and Realtek so I just disable ATI, sound still works but not sure if that fix the problem. Thanks!
