BSOD playing DotA2.

Hello guys, this is my first post here. I was playing dota 2 another day when sudently my pc crashed and i got a BSOD. I need some help to figure out what happened to my sistem.

Hello, and welcome to SevenForums!

Your BSOD seems to be caused by your DirectX Graphics MMS driver:

Code:

*******************************************************************************
*                                                                             *
*                        Bugcheck Analysis                                    *
*                                                                             *
*******************************************************************************

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault).  The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
        use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
        use .trap on that value
Else
        .trap on the appropriate frame will show where the trap was taken
        (on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
Arg2: 0000000080050033
Arg3: 00000000000406f8

---------

However, I've also highlighted near the top that your NVidia driver could not be loaded.

The 0x7f error occurs when there is faulty or mismatched hardware (usually memory). I'd recommend running Memtest86+ and checking to see if there are any errors. If there are, then your RAM is failing, and you will need to replace it.

If there are no errors, then it must be your GPU that is failing, which would be unfortunate considering the price of them nowadays...

Well, best of luck,
