***sry, additional informations will be provided ASAP as guided by the forum rules. I'm doing it now.
This is the link to my dmp file:https://docs.google.com/file/d/0B1zZyTTrGp6LQnFvbHRZVHJzczQ/edit?usp=sharing
My NB was bought at ~ Noc, 2012, and started to BSOD since March, 2013.
After a few crashes, I used Acer's eRecovery to recover my system and wiped out everything on C drive,
but it still crashes, and crashes are getting more frequent recently.
At the beginning, the dmp files reported that crashes might be caused by ntoskrnl.sys with error "DRIVER_POWER_STATE_FAILURE",
which is exactly what I've seen on screen when BSOD came out.
Then I searched the net, learned how to use Windbg, and after some works (getting additional symbols to work etc.),
the !analyze -v gave me some new information that BSODs were actually caused by nvlddmkm.sys with error "PAGE_FAULT_IN_NONPAGED_AREA"
I recovered my NB again, set the Driver Verifier to active, and got this BSOD yesterday.
Anything from here is probably beyond me, plz help, thanks :)
I will continue to upload dmp files if BSODs occur. By this time this one is the only one I have now, because I recovered it yesterday.
And sry for my poor English; I am not a native speaker
