This was probably caused by the following module: ntfs.sys (Ntfs+0x8EF7)
Bugcheck code: 0x1000007E (0xFFFFFFFFC0000005, 0xFFFFF8800161DEF7, 0xFFFFF88003738728, 0xFFFFF88003737F80)

Bug check description: This indicates that a system thread generated an exception which the error handler did not catch.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.

crash dump file: C:\Windows\Minidump\022414-32651-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x75BC0)
Bugcheck code: 0x1A (0x31, 0xFFFFFA8006D843B0, 0xFFFFF880066F2000, 0xFFFFF8A00EC80DA5)

Bug check description: This indicates that a severe memory management error occurred.
This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.
