BSOD after sleep and USB-breakdown
Hello everyone,
After trying everything I could think of, I was hoping you guys here could help me with a very annoying BSOD problem.
The problem only occurs after trying to get Windows 7 to sleep. Sometimes it works without any problem, but most of the time the screen goes black but the fans keep spinning. As far as I can see there is no actual CPU or HDD activity. And after about 10-15 minutes of being in this weird state, the computer finally shuts down. But when I try to wake it, instead it reboots and gives me a nice BSOD-message on reaching the desktop.
After Googling this seemingly widespread problem I have tried everything other people were advised: disabled media sharing in WMP, set the right energy settings and such. However, the problem persists.
The WhoCrashed report isn't helping me very much either:

crash dump file: C:\Windows\Minidump\011111-31715-01.dmp
This was probably caused by the following module: ntkrnlpa.exe (nt+0xDCD10)
Bugcheck code: 0x9F (0x3, 0xFFFFFFFF87B8A030, 0xFFFFFFFF82F29AE0, 0xFFFFFFFF85CA0D08)
Error: DRIVER_POWER_STATE_FAILURE
file path: C:\Windows\system32\ntkrnlpa.exe

Bug check description: This bug check indicates that the driver is in an inconsistent or invalid power state.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time.

This was probably caused by the following module: ntkrpamp.exe (nt!KeBugCheckEx+0x1E)

A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: ntkrpamp.exe .
Google query: ntkrpamp.exe DRIVER_POWER_STATE_FAILURE
So, I'm hoping someone here could make anything of this?
System info:
Windows 7 professional 32bit (full retail, clean install). The age of my hardware varies greatly. However, the main portion of my computer would be about two years old.
Maybe somewhat of a hint to the cause of this problem, might be the fact that the BSOD occurs every time when for some mysterious reason the USB devices stop working. That is, my WiFi-adapter gradually loses speed (though no weakening of the connection is displayed), until the internet connection is completely gone. Any USB device plugged after this won't work, including the adapter itself. The only USB devices that continue to work are my mouse and keyboard.
I hope you guys have any idea what is causing this mess!
