Windows 7 often unexpected shut down

[201power]

Hi guys

Recently I've experienced often unexpected shutdown.
Can you guys help me on this?
Normally the shutdown won't have minidump file, this time I caught one!
I've attached the minidump file and sysdata file in the attachment.
Thanks a lot!

About all I can do is pass this along.

There is a BSOD forum where most of the folks that handle Blue Screens hang out. There is a sticky there about how to ask for help with a Blue Screen.
