welcome to Seven Forums. I will try to assist you in this. Have you done any work inside your computer recently or installed any new programs or drivers?

Your error is many times caused by memory or memory corruption.

PAGE_FAULT_IN_NONPAGED_AREA (50)
[COLOR=red]Invalid system memory was referenced[/COLOR].  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: [COLOR=red]fffff8a00866c000, memory referenced.[/COLOR]
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff8000315bbdf, If non-zero, the instruction address which referenced the bad memory
 address.
Arg4: 0000000000000000, (reserved)

This is not always caused by bad memory, but can be caused by other things too. So to begin with, boot into safe mode with command prompt and run this,

Open a elevated command prompt ( click start, type cmd in the search box, right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know.

Also, please run memtest86+

Next I would like you to run memtest86+. It is quite a long test as it needs to be run for 8 complete passes all at the same time. Please download the test from Memtest86+ - Advanced Memory Diagnostic Tool. Although the names atr similar, this testis much better than memtest86. It needs to be run for 8 complete passes or until you get an error. If you get an error, stop the test. In the link above if you will go down to the middle of the page you can download either the ISO file which needs to be burned to a CD by Windows image burner or any disk image burner you choose. Or you can download the auto installer for USB Flash drives to run it from a flash drive. Whichever you choose, be sure to download the zip file and extract it. Each Pass consists of 10 tests, each pass checks a different thing and each pass checks different things. It takes a minimum of 8 passes to completely check the ram, more passes are better. It will take quite a number of hours to do the test, so it is usually better run over night. To run the test, boot from the media you chose and don't press any keys, the test will run automatically and will continue running until you tell it to stop. It will tell you how many passes it has run and how many errors are found. If it finds errors they will show up as red lines at the bottom of the page. It will take somewhere around 9-10 hours to check my computer with 8 GB of ram. If you have more it will take much longer.

So, you are booting into Windows OK now? If so, I would still recommend running memtest86+ exactly as I described in my post. many times this type of error is caused by memory. What happens is when you BSOD, the BSOD can cause system files to become corrupted, which is what you just fixed, but the underlying problem still exists.

That would be great. Be sure to download it from the link provided and run it for 8 complete passes all at one time unless you get an error. If you get an error, you can stop the test. The download links are in the middle of the page and you can use the 5.01 or the 4.20, it won't matter about the test. Just with the 5.01, it will tell you to press certain buttons when it first starts, don't press anything. I use the 4.20, they are both basically the same test but I've had trouble with the 5.01 getting it to continue running. Others have no problems. Use whichever you want.
