A literal interpretation of your most current dump is as follows:
A page fault occured and ntfs.sys was called to read or write a page from/to the hard disk. Ntfs.sys was not able to perform the read/write operation and an exception (0x24) was generated.
A page fault occurs when the memory manager determines that an address has been accessed which is not in physical memory and must be fetched from virtual memory on the hard drive. Pages are 4k blocks of memory (virtual or physical).
The memory manager relied on ntfs.sys to fetch the virtual memory block which was unsuccessful.
This leads one to believe that either the hard drive has physical defects (bad blocks) which can not be read or the actual file system which exists on the drive is corrupted. In the latter case a chkdsk /r should be able to resolve the problem.
Make sure you have the most current bios for the motherboard installed.
If you are using a raid configuration get rid of it for the purposes of this debugging session.
All of your
drivers look to be current, however you may try to run
driver verifier anyway:

Upload any additional bsods that you may get.
Edit: Try disabling(uninstalling) any virus scanners, backup programs, or disk defragmenter tools that continually monitor the system.
