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 the Minidump files but am not sure how to interpret them. Does anyone know how I can decipher this error code and prevent the BSODs? Thanks.
