Random BSOD, error 0x0000009f (DRIVER_POWER_STATE_FAILURE), Asus N76VZ
Hey guys,
I'm having random BSOD's on my Asus N76Vz since the day one. It's been going on for approx. 4 months now. I get approx 2 BSODs per week randomly. It's always the same thing; error 0x0000009f (DRIVER_POWER_STATE_FAILURE). It happens randomly, although it seems that it happens more often when computer is idle (not standby). I did several stress tests, and I never got the BSOD during the process.
There are few things I should mention;
1. Asus states that this computer supports a maximum 8GB RAM, however I am using 2x8GB, as many other people too (although they are not reporting problems similar to mine). I did run the memtest, and everything seemed to be fine.
2. My system drive is OCZ Agility 3 SSD 120GB, and recently I have flashed the latest available firmware, which seems to have reduced the number of BSODs slightly, but not eliminated. This could be accidental, but I thought I should mention it.
3. Many users of this series (Asus N76) are reporting issues with sound card producing crackling noise, when the sound card wakes up from longer period after not being used. This also affects my machine. As a workaround, many people set the Stereo Mix as Default recording device in Realtek HD Audio settings, which solves the crackling problem, and doesn't change anything in functionality. I have a feeling it has something to do with power management, which might also have something to do with BSODs.
4. There were some problems with Optimus driver switching from Intel integrated GPU to NVIDIA, which resulted in constant color settings resets. This got solved by uninstalling crappy Asus/Intel bloatware.
Regarding the drivers, I have tried all possible combinations I could think of. Especially the Nvidia GPU drivers. Now I'm using drivers provided as latest on Asus website. It doesn't seem to matter. Any drivers I try, I always get the BSOD eventually.
In normal conditions, I would've already send my latop to the service center, however, the only available service center, here where I live is notorious for extremely long waiting periods (30-180 days) and even worse, for returning computers in worse shape than they were shipped in. All kinds of bad things happen there, like breaking cases, stealing components and such stuff. And I want to avoid this if possible.
Otherwise than the BSOD's, once properly set up, this is a fine machine. That's also the reason why I have hung on it for so long inspite of BSOD's.
Please help,
Thanks
