Retail Win 7 Pro x64 (clean install, but was doing the same thing before reinstall)
Hardware about a year old, except for relatively recent RAM addition - but Memtest checks out with 0 errors.
The BSOD seems to happen at random; I can't find any sort of pattern here.
In addition to the attached files requested in the sticky, Bluescreenview outputs the following:
Filename : ntoskrnl.exe
Address In Stack : ntoskrnl.exe+7c229
From Address : fffff800`02c0d000
To Address : fffff800`031f5000
Size : 0x005e8000
Time Stamp : 0x4f558b55
Time String : 06/03/2012 04:58:13
Product Name : Microsoft® Windows® Operating System
File Description : NT Kernel & System
File Version : 6.1.7601.17790 (win7sp1_gdr.120305-1505)

Full Path : C:\Windows\system32\ntoskrnl.exe
are up to date except for NVIDIA HD Audio, which I didn't bother installing since I don't use it (hence disabled devices). However, this WAS installed prior to fresh OS install, and the BSOD was happening then too.
Any ideas would be greatly appreciated.
