I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Load the dmp file into Blue Screen View from Nirsoft.  It says:

Driver Power State Failure, Bug Check 9F Parameter 3.

Microsoft says the following (look under Parameter 3 XP and later)

It is not altogether revealing. Does the computer even start?

Also, try testing memory ( and the hard drive (Dell hard drive test tool)
windbg sys this :
FAILURE_BUCKET_ID:  X64_0x9F_3_IMAGE_nvlddmkm.sys

BUCKET_ID:  X64_0x9F_3_IMAGE_nvlddmkm.sys

so it looks you are having problems with the video driver - try a newer, or older version
restoring  the system to a date it worked ok can also help !

here all the drivers for W7 - 64 bit :
