I occasionally (always at the least convenient moment...) receive this BSOD on my Windows 7 desktop PC:
Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 1033
Additional information about the problem:

Files that help describe the problem:
C:\Windows\Minidump\010812-16578-01.dmp
C:\Users\al\AppData\Local\Temp\WER-37500-0.sysdata.xml
Trying to find out more information about this seems to be futile because the file C:\Users\al\AppData\Local\Temp\WER-37500-0.sysdata.xml doesn't exist (the folder exists, but not any file that starts with "WER"), and attempting to analyze the minidump file yields the following:

Well, hal.dll and ntoskrnl.exe are part of the OS and there doesn't seem to be anything I can do to upgrade those "drivers".
I know that the hardware is perfect (including RAM voltages in BIOS etc) because this same exact system works perfectly with Ubuntu 8 and Ubuntu 10 (triple-boot config). The problem is definitely in the system software, but how do I find out what it is?
