BSOD playing TERA online, error 0x0000007e

Today's Update:

-MemTest: 8 hours run, 9 passes, no error.
-SFC.EXE /SCANNOW: got error with windows resource protection or something like that, after reboot then 3more scans no more violation or error found. But my windows activation popped up (i'll work out that)

So,um...what's supposed to be the problem is? is it TERA causing that? or that windows resource protection causing that faulty BSOD?

N.B: i try playing other game tonight like Dragon Nest and it runs perfectly with maximum option :)

The problem with figuring out these problems is that often times it is tough to pin down the cause of the crash, it is looking like it may be either that you had some file system corruption or that your video card driver is doing things that it should not be doing. Also, I'm curious why running the system file checker would cause your windows to stop being genuine?

i try to pin 1-1 the BSOD by disabling some service.
to further remove that BSOD i even dusting my hardware twice, but before it was never happened.
i myself confused with that, no graphic error/memory corruption, or maybe dust happened to cause some faulty BSOD here.

So far after dusting here and there, remove the GPU and attach it again, so far only one BSOD happened, i don't know why, it happened when i'm opening 2 browser at once other than that nothing more.
I guess it's solved, thank you for you time and attention, i really appreciate your quick reply.
If some problem happen again, please help me
