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: fffff8800403e000, memory referenced.
Arg2: 0000000000000001, value 0 = read operation, 1 = write operation.
Arg3: fffff8800feea1ce, If non-zero, the instruction address which referenced the bad memory
 address.
Arg4: 0000000000000000, (reserved)

Install current version of the above driver. In addition
If overclocking restore normal settings
SFC /scannow

Scan with your Anti Virus
How to Find Drivers
search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone - will help you search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- - if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
- The most common drivers are listed on this page: http://www.carrona.org/dvrref.html
- - Driver manufacturer links are on this page: http://www.carrona.org/drvrdown.html
To remove any left over driver remnants, especially from graphics cards, use driver sweeper
www.guru3d.com/category/driversweeper/

After performing all of the above, post back with any new BSOD reports, or indicate that the attempted repairs were successful.
If any links do not work, if clicked, please copy and paste to browser address bar.
Remember that several attempts may be required before we can solve your BSOD problem. These reports are not definitive but merely point the way to a solution.

I would replace the driver as shown. If no effect, test hard drive
Test Hard Drive www.carrona.org/hddiag.html

If problems continue, perfrom a repair install., which will correct the corruption shown by the sfc.

What brand HD?

I do not see Corsair on the list of SSD that are tested,
but this from the Corsair website.

What programs can Corsair recommend to test the performance of my Corsair SSD? A » ATTO, CrystalDiskMark, HDTune, SiSoft Sandra and Everest are all very good benchmarks of your SSD performance. However, all Corsair SSD specifications are published based on ATTO performance.
