0x9F DRIVER_POWER_STATE_FAILURE on standby; ntoskrnl to blame?
Ever since I installed Service Pack 1 on my Win 7 Pro x64 system, I had an intermittent issue where going into standby sometimes... maybe a quarter of the time? ...it would stay on for ten minutes before shutting off entirely. It wasn't until literally a year later, when I left the monitor on and didn't leave the room, that I managed to catch a BSOD flashing on the screen for a moment just before the computer shut off and realized I might be able to use the code. To make a long story short, I found a tool called NirSoft BlueScreenView, which let me look up the crash data and see that it was an 0x9F DRIVER_POWER_STATE_FAILURE caused by, allegedly, ntoskrnl.exe. Here's the problem — the documentation I've seen on this issue says I need to repair my install from the Windows 7 DVD-ROM to regain a non-corrupted copy of that file. But, if this file was replaced when the Service Pack was installed, doesn't that mean the copy on my disc is outdated?
At any rate, here's a zip file with, I guess, all of the kernel dumps from the BSODs that were still on file as of today and whatever else the Seven Forums utility recorded. Most of the dumps are from crashes related to this issue; the one dated April 3 is probably the only one you need to look at.
