A bugcheck (BSOD) is a mechanism to protect your PC from damage.
Bug Check 0x9F: DRIVER_POWER_STATE_FAILURE
This bug check indicates that the driver is in an inconsistent or invalid power state.

To see the driver which causes the issue, I have to take a look at the dumps with the Debugging Tools for Windows.
Please start the Windows Explorer and go to the folder C:\Windows\Minidump. Next, copy the dmp files to your desktop, zip all dmp into 1 zip file and upload the zip file to your public Skydrive [1] folder and post a link here.
