Thanks for the reply.
I just had another BSOD while in the chess program.
Stop: 0x0000007E with 3 drivers possibly causing problem "fltmgr.sys" ; ntoskrnl.exe ;
and USBSTOR.sys
Bug check string: "System_thread_exception_not_handled"

Based on the zip file I uploaded, did you see any commonalities between the 4 BSODs?

All of them have a thing common, most occuring cause is device driver, though overclocking can cause many problems too.

I only saw 1 dump, where are the others? Did you run disk cleanup or another cleanup utility?

I have uninstalled ASUS AI Suite 3.
I have updated Samsung 840 SSD firmware to latest firmware. Samsung Magician states that drive health is "Good."
(I have already done thorough chkdsk on C:, the SSD and on D:).
I will be working on the other items on your list and will report back as I do those items, although updating the BIOS of Asus X-79 Deluxe mobo might be tricky.
Note that all BSODs have occurred while the 6 cores were under full load (chess program), e.g., while O/C to 4.4 GHz, instead of stock speed of 3.4 GHz of the Intel i7-4930K. (It seems to run at 1.2 GHz when not under load.) So reverting to stock speed is very unlikely to occasion a BSOD.
Thanks for your pointers.

Please upload the chkdsk log

Hi Eric:
I use a variety of chess programs. But the relevant BSOD aspect is that a chess program, like Prime, will push all 6 cores to near maximum usage. Have you looked at my zip file?
If the causes of the 5 BSODs are unrelated, which is more likely: a bad SSD (where Windows is), or corrupted Windows files?

Actually i am only interest in the chess program, as being a chess player since half of century.
Not much related to your this problem.

As for your this issue, try to think when this started.
Such as install any program &or updates, including surfing internet.

This is not in my knowledge as i do not have any BOSD before.
So, i am not much help to you.

Thanks.

Just had another BSOD while in chess program. I can upload the log if you like but probably nothing new as BSOD again caused by "ntoskrnl.exe".
I will work on gathering system specs.
I am uploading CPUZ system specs. Let me know if this is sufficent.
Thanks,
CMA

but probably nothing new as BSOD again caused by "ntoskrnl.exe".

If we'd do that with everyone there wouldn't be a BSOD Team, ntoskrnl is the Windows kernel. Windows files are only blamed when there is nothing else to be blamed directly and as such are an invalid cause.

It is recommended to upload a new zip when you want to post about a new BSOD.

Please follow the quote below regarding CPU-Z, I'm not really a fan of the text files that can be created with CPU-Z

Please run CPU-Z | Softwares | CPUID, open it and make screenshots of the following tabs

CPU
Mainboard
Memory
SPD*
Graphics

*SPD shows the details of each stick, you can show the details by choosing different slots in the left upper corner.
Please make screenshots of each stick.

Please post each screenshot in your next reply/replies.

I have finished filling in my system specs using the SevenForum automated tool + additions you suggested.

I did a routine disk cleanup yesterday but fortunately have recovered the dump from 9am on 7/13 (attached) which should show several dumps.
