http://www.tomshardware.com/answers/id-2223087/kernel-data-inpage-error.html
the KERNEL_DATA_INPAGE_ERROR occurs when memory in the kernel's paged 
pool is swapped to the hard disk and cannot be read when needed at a 
later time.
Windows broadly divides memory into three pools:
The kernel non-paged pool
The kernel paged pool
The user paged pool
  The kernel non-paged pool contains memory that must be in memory at all 
times. This includes all of the memory used to handle interrupts, track 
thread and process states, and handle deferred procedure calls. Memory 
allocated to the kernel or drivers from this pool will always remain 
resident in memory at all times, it will never be swapped out to the 
hard disk drive and referencing memory in the non-paged pool will never 
generate a page fault (in fact, PAGE_FAULT_IN_NONPAGED_AREA is another 
famous BSoD).
  The kernel paged-pool contains kernel memory that can be swapped to a 
page file or swap file located on a secondary storage medium such as a 
hard disk drive. If memory is infrequently used, it may be swapped out. 
If the kernel references memory located in the kernel paged-pool it will
 generate a page-fault interrupt which will bring it back into the 
physical memory (note that as I mentioned above, the page-fault 
interrupt handler operates only on non-paged memory).
  The user paged-pool contains memory that can be allocated to user processes.
To best address your question, imagine a scenario when an application 
causes a page fault by referencing memory that has been swapped out to a
 page file that is located on a secondary storage device that has been 
removed or is inaccessible. That memory can no longer be found, so the 
application must be terminated as it can no longer proceed.
The same is true when the kernel causes a page fault by referencing 
memory that has been swapped out to a page file that is located on a 
secondary storage device that has been removed or is inaccessible. The 
kernel cannot proceed to a consistent state, so it must terminate and 
halt the machine.
If you have any removable storage devices, make sure that they are 
configured as such. If they contain page files (pagefile.sys, 
swapfile.sys, hiberfile.sys) they may unwittingly be used to store 
memory and that memory will go with them when they are removed. Your 
machine will run uninhibited until something references the memory that 
has now disappeared at which point the referencing task will fail.
Your hard disk drive and SSD may also be failing. 
 
CHKDSK /R will scan 
for bad sectors but it won't catch non-deterministic read errors and 
long-latency events. Check the health of the drive using a vendor 
supplied S.M.A.R.T monitoring tool.
------------------------------
**if you get a inpage error and do not get a memory dump:  Look for a drive disconnection issue**
a common cause of a kernel inpage error would be a disconnection of a drive.
This can be caused by some simple issues,  Thermal expansion/contraction
 of the sata cable can make and break a connection several times a 
second.   You might consider checking the cable connections for your 
drive with on the sata port.
-There can be bugs in the chipset drivers for the sata port ( update 
chipset drivers, or change the cable to connect to another    Sata 
chipset if you have 2.
-there can be bugs in the BIOS setup for the electronics on your board (update the BIOS)
- special issues involving solid state drives.  where the SSD gets behind on it cleanup routines and takes too long to respond
causing windows to reset the port.  and the drive does not reconnect.
- sometimes you can enable hotswap in BIOS on the sata port of the drive 
and it will reconnect (hides the disconnect issue but you don't 
bugcheck)
- sometimes you have to update the firmware of the SSD because of bugs that cause the drive not to respond correctly 
  (often caused by using image software to install the OS)
- sometimes you can boot your machine into BIOS and leave the SSD drive 
powered, after 5 mins the cleanup routines in the drive will start and 
it can fix the errors.  (just leave it powered and not in use for a few 
hours)
[most of the time you will see a event viewer error from the disk subsystem that indicates that the sata port was reset]
You can also get inpage error with some physical problems with the 
memory sticks (basically, thermal breaks on certain pads where the 
memory chips connects to the circuit board.  The defect is hard to 
detect because and most people will think it is related to when they 
first turn on the machine but it occurs due to the heat cycle of the 
memory stick.  (when the board is cool, the circuit contracts and opens a
 address line (line disconnected therfore wired to 0 logic) drivers are 
loaded into the memory then the memory chip heats up in 5 to 7 seconds 
circuit and the connection is made and the address line gets set 
correctly.  This can cause a whole block of memory to move after a 
device driver was loaded into it.
 Results is memory corruption that 
only occurs when the memory is cool.  And the memtest86 would not find 
this type of failure.

The error code 
KERNEL_DATA_INPAGE_ERROR STOP: 0x0000007A
 states that the requested page of kernel data from the paging file 
could not be read into memory. It appears that there are some issues 
with the hard disk.
Method 1: I would suggest you to try the steps provided below and check if it helps.
a)       Click on Start, type Command Prompt, right click on it and select to
run as administrator.
b)       In command prompt, type 
chkdsk volume: /f /r and hit enter to check and 
repair any volume disk errors or bad sectors present on the drive which 
would be causing this problem.

try ssd life  :

download UBCD, and run memtest86+ for ram (couple of passes)
For an SSD - check the manufacturers site for a diagnostic tool, or post the model here
eg, for an intel SSD:
