I have a Dell OptiPlex 755 running WIN 7 Ultimate.  Ever since I installed a Samsung SSD 850 evo I get a BSOD every morning.
The drive is 232 GB with 61.9 gigs free.  My only automated procedure at night is a backup using NovaBackup by Nova Stor and it isn't backing up any files on or from the SSD.  I've attached two BSOD screens.  I've tried using Samsung Magician to optimize SSD performance and I've increased the page file  size to 600 mg.  Any ideas?

Agreed.  Also if you see and failures or warning in System and Application logs, that would also be helpful.

Two suspects are RAM and drive. Thus check if Samsung drive hast latest firmware version.
Check the RAM as well. There is RAM testing rool on Windows installation media, use it.

Firmware is latest.  Did RAM test, left the computer, bsod when I returned.  So, bad ram?  Curious coincidence that it occurred after SSD install.  Is there away to isolate which stick? Or is it trial and error?  Thanks.

Good day,

First shutdown safely the machine, remove power cord and try to switch the machine ON, to release any left electric charge,  before removing all memory sticks installed, except one. Run Memory tests.
If the RAM stick tested O.K. follow the above mentioned safety steps, mark the memory stick and replace it with another one. Till you find the defected one(s).

BTW, any memory errors,  means you have either bad RAM or a bad slot. You will have to run further tests to determine which is the case.

Sometimes iut is enough if you exchange the RAM stick places. So put stick out from slot 1 and insert it into slot 2. And the one from slot 2 into slot 1.

Hi all,

Interestingly, I spoke with a computer guy I know and he tipped me to a program called "WhoCrashed"  and it pin pointed the problem driver causing BSOD.  I am posting this so fellow BSOD sufferers are aware of this excellent program.  Thank you all for your help.  Here's the "WhoCrashed" report:

"On Thu 11/12/2015 6:51:16 PM GMT your computer crashed
crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: pffilter.sys (pffilter+0x32DF)
Bugcheck code: 0x50 (0xFFFFFFFFFFFFFFD0, 0x1, 0xFFFFF80002EBF0F1, 0x0)
file path: C:\Program Files (x86)\IObit\Protected Folder\pffilter.sys
product: Protected Folder
company: IObit Information Technology
description: Protected Folder filter driver
Bug check description: This indicates that invalid system memory has been referenced.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: pffilter.sys (Protected Folder filter driver, IObit Information Technology).
Google query: IObit Information Technology PAGE_FAULT_IN_NONPAGED_AREA"
