Page Fault In Nonpaged Area crash? (blue screen of death)

Hello all, I've recently have had computer crashes from what appears to be from this "page fault in nonpaged area" error. This error seemed to have happened after I updated my drivers. I then reset my drivers to their original state but to no avail. I tried to research the problem but have come up short, I downloaded a program to help identify the problem. I've had mostly two different reports, the reports are as follows.

On Sat 7/19/2014 6:34:00 PM GMT your computer crashed
crash dump file: C:\WINDOWS\Minidump\071914-36125-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x153FA0)
Bugcheck code: 0x50 (0xFFFFFA80115164A0, 0x0, 0xFFFFF803C9C8D5A3, 0x2)

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 the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

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.

I have multiple crash reports like this and I don't know how to fix it. Any help with this problem is greatly appreciated.
