Windows 7: BSOD errors A1 (Memory_Management) and A (Irql_Not_Less_Or_Equal)

BSOD errors A1 (Memory_Management) and A (Irql_Not_Less_Or_Equal)

Hey everyone,

So I'm a little green at posting on forums for help, normally I read and fix things myself, but this time I can't figure it out.

Background:
I have had a very solid stable system since 2010, then I decided 6 GB of RAM and a 9800GT/GTX560Ti wasn't enough. I sold these parts away and replaced them with 24 GB of RAM and a GTX560Ti 448 edition. The instant I throw these new parts into my box I start getting the two different BSoD errors (the ones in the title). I have cleared everything of my previous overclocks with the upgraded components.

System Specs: (bolded is what was introduced to the system which created the errors)
Windows 7 Professional x64
i7 930
EVGA 132-BL-E758 (Motherboard)
EVGA GTX560Ti 448 FTW Edition
Patriot Extreme Performance (24 GB of RAM)


If you need to know anything besides the core components that I have, let me know. Attached are the dump files.

The story so far:
I have ran Memtest overnight on all the sticks of RAM and nothing comes up, it claims they're all good. I'm not sure how to test the graphics card, but what I can tell you is that I can login to Windows and within 5 minutes the BSoD shows itself. When in safe mode, (where I am right now), it runs more stable, but I have had it BSoD in here as well; It's just nowhere near as often. So, this makes me think its not hardware related and hopefully it's not because I have no other RAM sticks or graphics card to test with.

My thoughts:
I only used 3 of the 6 slots for RAM on the motherboard before this upgrade so initially I thought maybe I had a bad slot. I can't disprove that, but I still get the BSoD when using only 1 stick of RAM in a slot that was previously known as working. I uninstalled the graphics driver for my old GTX560Ti and downloaded the latest driver for my new graphics card and still get a BSoD.

From BlueScreenView I have deciphered that the driver/executable causing the problem are: Ntfs.sys and ntoskrnl.exe

Any and all help is appreciated,

Ilithis

PS: Thanks in advance!

I figured I'll keep this thread more like a journal of what I have done to assist others with the same issue and to assist others helping me.

I have uninstalled Daemon Tools per loads of other threads.
I have uninstalled DisplayFusion because it crashed on me once when not in safe mode and when I clicked 'close program' the BSoD instantly appeared when I clicked. Coincidence, I think not!

I have also run verify drivers. When I did, I ran it against all non microsoft drivers. When I rebooted for the changes to take effect, the BSoD struck a few minutes after logging into the machine. The latest dump is the BSoD that I got while running verify drivers.

I have also started going through my 6 sticks of RAM, one by one, to see if the BSoD comes up on each of them.

I'll keep you all in the loop, just documenting what I'm doing makes me feel better about this issue.

First, disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
verifier /reset
-> Restart your computer.


Please remove any CD/DVD virtualization software, such as Daemon Tools/Alcohol 120%, as they use a driver called sptd.sys that is known to cause BSODs. Use add/remove programs to remove the software. After removing the software, use the sptd.sys uninstaller to remove sptd.sys from the system.

I prefer TotalMounter as my CD/DVD virtualization software as it allows me to burn images to a virtual CD/DVD if I just want an ISO file instead of a disc, and it is free.

Many use MagicISO - Convert BIN to ISO, Create, Edit, Burn, Extract ISO file, ISO/BIN converter/extractor/editor as well, which is also free.
