Windows 7: Need help for BSOD-BCCode a

Need help for BSOD-BCCode a

I think I've got a persistent BSOD problem. It occurs about once a month. This latest BSOD occured at 1:37 am PST. I had gone to bed, leaving the computer running a program called Freemake, which is a video transcoder with the option to shut down when the transcoding finished on a file.
I've tried to zip the .dmp file at:
however I get the error message reading:
File not found or no read permission
I've tried different settings in the properties box to get read permission but I have no idea what it's supposed to be. My user account is as the administrator.
I was able to find the file at:
C:\Users\Phunbunnies\AppData\Local\Temp\WER-7310004-0.sysdata.xml. Not knowing what to do with that, I began writing this post. Then I thought "Maybe I can zip that file." so I went back to C:\Users\Phunbunnies\AppData\Local\Temp\ but CWER-7310004-0.sysdata.xml was no longer there.
Here's what the error window displays:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.
Locale ID: 1033

Additional information about the problem:
BCCode: a
BCP1: 0000000000000000
BCP2: 0000000000000002
BCP3: 0000000000000000
BCP4: FFFFF800030D5452
OS Version: 6_1_7601
Service Pack: 1_0
Product: 256_1

Files that help describe the problem:

These are my system specs:
Windows 7 64-bit Professional SP1 updated as of 06/05/2012
Intel i7-2600
MSI Z68 GD-80 G3 mobo
BIOS V18.7 (MS-7672)
16 GB G. Skill memory F3-12800CL9-4GBRL
Intel 320 160GB SSD (SSDSA2CW160G3)
(2) Acer P236H monitors into integrated graphics
No other video card installed
Seasonic X650 PSU
Corsair 500R case

This is the first OS on this homebuilt system I put together from all new parts (December 2011) excepting the SSD/all HDD/both PLDS-ROM drives and both monitors.
OS is from retail upgrade disc and initially installed December 2011. Reinstalled from System Image
April 2012. This is the 4th or 5th BSOD in as many months.

Thank you for your help.

We've seen a number of BSOD issues with SSD's. Here's the information that I've compiled so far:
There's not a whole bunch available to test SSD's. The "easiest" test is to remove the SSD, install a platter-based hard drive, install Windows and test for stability that way.

Here's some suggestions:
- Update the SSD's firmware to the latest available version (VERY IMPORTANT!!!)
- Update the motherboard controllers drivers to the latest available version from the controller manufacturer (NOT the mobo manufacturer unless you can't find any on the controller manufacturer's website)
- Slow the memory (RAM) down to the next slower speed (I've only seen one person who claimed that this worked for them).
- Use any manufacturer's utilities that you may have. If you don't have any, then try this free one (I haven't used it myself): Crystal Dew World
- Update chipset and storage controller drivers to the latest available from the manufacturer of the device (not the manufacturer of the motherboard). Be sure to update ALL controllers on the motherboard!
....NOTE: Recently (Nov 2011) we had BSOD issues with the Marvell 91xx controller and an SSD. You may have to switch controllers also.-
Replace the SSD with a platter based hard drive and see if that stops the BSOD's. If it does, then it's likely that there's a problem with the SSD OR an incompatibility with your system.
It's my opinion that SSD's aren't reliable enough (with current hardware) to be used on a system that needs to work reliably. Until I see reliability I will not recommend, nor will I use, SSD's for critical applications.
06 Dec 2011 - This post tends to confirm issues with certain SSD chipsets and certain controllers - [SOLVED] cant find the cause of BSOD F4 - Tech Support Forum
29 May 2012 - The frequency of BSOD's with SSD's seems to have been decreasing over the last several months. It may be approaching time to re-evaluate my stand on their suitability for use in production systems.
Blue screen blames your video - but there's a lot of storage stuff in the memory dumps.
Update all storage drivers (Intel, Marvell, and USB 3.0)
Update Intel video drivers

Update Realtek audio drivers as they date from 2009

Post back for more suggestions if this doesn't fix your problems.

The following info is just FYI, I've already addressed the issues that I saw in the above paragraphs

I'll follow up

Thanks Usasma. I'll follow your suggestions. As an aside, the SSD in question was part of another system last year for about 6 months without a problem A Foxconn duo core from Dell. But as you indicate, compatibility with my mobo may be the problem.
