BSOD when shutting down

Hi, I recently started getting a BSOD when shutting down. My computer will run normally after I turn it on, then when I go to shut down it will hang for 15-20min then BSOD. I never had this problem before.

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.3
Locale ID: 1033

Additional information about the problem:
BCCode: 9f
BCP1: 0000000000000003
BCP2: FFFFFA80084C9BF0
BCP3: FFFFF80004CF23D8
BCP4: FFFFFA8009B6CA80
OS Version: 6_1_7601
Service Pack: 1_0
Product: 768_1

I have attached the DM Log Collector zip file to this post.

Can anyone take a look at this for me please? I'd really appreciate some help.

UPDATE: Found a solution, although I don't quite fully understand why it worked. I asked somewhere else and someone suggested a check my power connections. I had my two hard drives and my DVD drive all connected on the same single power cable. I seperated them and put my OS drive on its own cable connected to the PSU and haven't had a BSOD since.
