I've seen quite a few threads about this already. But haven't really seen any fixed for it, So I'll add mine to the list in hopes a fix can be found.
I've been having this issue for a few weeks. I have contacted asus and they told me to download and repair the ASUS Splendid Video Enhancement Technology driver. That didn't work.
Here are my last few minidumps,

They told me to completely remove the Kasperky Internet Security I have. They also told me to remove and do a clean install of the 337.88 driver. Here is the link to that thread in case you wanted to read it.
http://answers.microsoft.com/en-us/windows/forum/windows8_1-system/windows-81-bsod-driverpowerstatef...I made a post on r/techsupport as well. A person there also told me to remove and re-install that driver. He recommended DDU to completely remove it. So I did that and re-installed 337.88. and for two days it was fine....and then it wasn't.
I've seen people say on this thread,
http://rog.asus.com/forum/showthread.php?48428-G750JM-Daily-BSODS-DRIVER_POWER_STATE_FAILURE that going back to 332.60 works, and also that updating to 334.43 also works.
So idk what I should do. lol Has Nvidia or asus even acknowledged this issue?
EDIT: Just talked to NVIDIA support and they told me to remove 337.88 with DDU and do a clean install of 340.43.
