BSOD every day when I leave PC and come back next morning

Every day when I come back to my custom built PC, it recovered from a BSOD. I've attached a .zip with the "GrabAll" files.

It appears that most of the files from the SF Diagnostic tool are missing, please re-run and then re-upload the files that it generates.

Sorry about that, I ran the tool and replaced my original post's attached file.

Just a thought; Does the temperature change in the computer's environment during the hours you are away ??
Just remembering a repetitive BSOD I had several years ago that ended up being a hairline crack in the motherboard. Temperature changed enough in the environment that the MoBo "moved" enough to disrupt the circuit, resulting in BSOD. Silly thing ran fine during the day.

Temp is quite consistent day/night. +/- 3 degrees F

I should also point out that I do occasionally experience the BSOD during the day.

Ok had a look through your files, and a couple of things to do:

First and foremost Remove Daemon tools, it is a known causer of BSODs, once it is uninstalled download and run this program

DuplexSecure - Downloads

when the tool runs if the uninstall box is grayed out your done and can close the window, if it is not click the uninstall button and let it do its job. DO NOT click the install button it will install a harmful driver that is known to cause BSODs

Once that is done run some hard drive diagnostics:

Hard Drive Diagnostic Procedure

Then run the system file checker to check for any file system corruption:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
If the command finishes with anything other than "no integrity violations found" run it two more times
If after the third run it is still not coming back with "no integrity violations" run the command at boot: http://www.sevenforums.com/tutorials/139810-sfc-scannow-run-command-prompt-boot.html

And last run some memory diagnostics:

be sure to let the test run for 8-9 passes (do this over night it can take a long time)
