Don't Boost Usb Storage Devices Replace Ntfs.sys

Recently, after varying times of general computer usage (internet, e-mail) ranging from 5 minutes to an hour, I'll get a BSOD, with the above title. I'll attach the dump files, and include the code from it below. I've tried some troubleshooting of my own. I've run memtest86+ on each of my 4 1-gig RAM modules, all clean. I've run Prime95, clean.

Should I try to repair my windows, or replace the ntfs.sys with a new one?. Also, I don't have any readboost of USB storage devices plugged in.

Code: PAGE_FAULT_IN_NONPAGED_AREA (50) Invalid system memory was referenced. This cannot be protected by try-except, it must be protected by a Probe. Typically the address is just plain bad or it is pointing at freed memory. Arguments:

Arg1: fffffa610b3a9ff8, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffffa6001219130, If non-zero, the instruction address which referenced the bad memory address.
Arg4: 0000000000000005, (reserved) ............
