I'll jump straight into details and the steps of what I did to have made my laptop showing BSOD.
Earlier time when I first bought this laptop:
1. Launched and played a game
2. Game playing halfway and Windows pops up a warning message about RAM being low (RAM usage was at 60% when I checked through Task Manager). Closed and ignored the message, few minutes later warning pops up again. This I ignored the message and continued playing.
3. Finished playing and quit.
4. Wanted to play another game, tried to launch and game executable not loading (Hard Disk activity status indicator not flashing). Waited for few minutes, BSOD suddenly appears with the error: "DRIVER_POWER_STATE_FAILURE".
5. Waited for it to collect info, auto restarted when it had finished.
6. Goes back to normal, but when playing a game for at least probably 20 minutes or more, the BSOD would initiate again.
Few days ago and to present day:
The problem is persists, of course, but I don't know what I have done that the warning message about low RAM doesn't come up anymore.
I've searched the internet and found out that it's because of either the Hard Disk not receiving enough power or power failure or for whatever reason. This has been frustrating me every time the BSOD occurs as I'm afraid I might lose my important data because of this.
My laptop specs:
ASUS K551LN
Windows 8.1
Intel Core i5-4200U @ 1.6 GHz, 2.3 GHz
NVIDIA GeForce 840M
4 GB of RAM

UPDATE –
My 4 ".DMP" files have been deleted by a program (it deletes junk files to free up HDD space), right now I don't think I can do anything to analyze the problem that caused BSOD, but I'l try to wait for the BSOD to occur again. Also, I installed updates for my Windows 8.1 so everything seems fine. -
UPDATE 2 –
Hoorah, the stupid OS is having BSOD again, and this time I have 2 .DMP files. It's all in gibberish though so I wonder how someone could read it. I have uploaded them to SkyDrive: http://1drv.ms/1pT2zDL

You have 2 different issues. The DRIVER_POWER_STATE_FAILURE bugcheck seams to be caused by the nVIDIA driver nvlddmkm.sys
Go to nVIDIA.com and try the latest (beta) driver for your NVIDIA GeForce 840M (PCI\VEN_10DE&DEV_1341).
The other dumps show a DRIVER_VERIFIER_DETECTED_VIOLATION bugcheck, caused by a driver called
TSSysKit64.sys
which is used by this tool:C:\Program Files (x86)\Tencent\QQPCMgr
Update or remove this tool and disable Driver Verifier again!
