My computer is as follows:
Vista x64 UE
Q6600 (OC'd to 3.0gHz)
GA-X38-DQ6
Corsair DDR2-800 1GB*4
8800GTX

It's Prime95 stable at 25hours, OCCT stable 2hrs, Memtest 86+ stable >14hrs no errors.

I play COD4 MP and UT3 on it for >4hours and no problems. I've done DivX video encoding overnight and no problems.

For some reason when it's idle, I get a BSOD with a Driver_Power_State_Failure error similar to this:

BCCode: 9f
BCP1: 0000000000000003
BCP2: FFFFFA8007C51050
BCP3: FFFFFA8007C55060
BCP4: FFFFFA8005720010
OS Version: 6_0_6000
Service Pack: 0_0
Product: 256_1

I tried googling this to figure out a work around but I'm not having luck narrowing down the culprit.

I have attached the Minidump files but I am not sure how to interpret them. I tried to use the advice in the stickies above without success. Does anyone know how I can decipher this error code and prevent the BSODs?

Thanks in advance.

See if this is relevant. http://forums.techguy.org/windows-vista/641640-driver-power-state-failure-vista.html

wow.... you're good.... i actually just powered on my Western Digital MyBook last week- I had turned it off during December when I was testing my overclock and recently turned it back on to use it as a backup disk

i'll turn it off when i'm not using it and i'll see if the BSODs stop... the Window Update could not be installed... it says "Update does not apply to your system."

Edit- Thanks a bunch!
