Windows 7: BSOD yet again, Please Help!

The timing of the chkdsk doesn't impact this.
What we're looking for here is a repeat of the bad chkdsk results
If that happens, then we've gotta start ruling out things. Here's a list of the most common problems that we deal with here:
- driver issues (mostly BSOD's)
- hardware problems
- compatibility issues
- software issues
- malware
- Windows issues

We fix most of these by following the procedure above. In most cases this'll tell us if it's hardware or not.
So, if you do everything above and the system still has problems - then it's most likely hardware
If you do everything above and the system doesn't have problems - then it's most likely a software issue

So we'll either start looking for hardware issues, or you'll be able to start adding programs to your system.
When adding programs, make a handwritten list of each and everything you do to the system. Keep this list up for a week or two - just in case one of your changes/additions is causing issues.

Good luck!

How can someone tell there are errors from the chkdsk report? Can you please show/tell me which line I should be looking for so I know what to look for after each chkdsk? Thanks!

The line that says if " it made (no) corrections to the filesystem" kind of sums it up.
If there were corrections made... Something was wrong.

There are other indicators, but this one is the most significant:
Windows has made corrections to the file system.

Been almost a week and so far, no errors after each chkdsk. However, I came across 2 BSODs; 1 (BAD_POOL_HEADER) was forced by trying to update the memory controller in Device Manager by selecting option to find drivers via the Internet -- this happened 2 days ago, 2 (MEMORY_MANAGEMENT) was when trying to install a remote desktop program called showmypc and after it downloaded the file, it crashed -- this took place earlier tonight. Tried to obtain info in Event Viewer but it didn't log them for some reason. So I went and did another BSOD Posting Instructions so pls check the zip file. Also, before I started doing the chkdsk, I switched the ram module settings from dual channel to single. System was stable until what I've explained above.

It is again an A1. It refers to MsMpEng.exe.

You are running MSE, which is fine, but I remember some problems I have seen before with a part of MSE: MsMpEng.exe, taking up ( and not freeing) resources, ultimately causing bsod's. The potential fix is easy. See this quote from Microsoft:

If its MsMpEng.exe ,then this issue may be caused as MsMpEng.exe service value is not set to Zero in the registry

To check for the exact issue, we need to add the MsMpEng.exe process in Microsoft Security Essential Excluded process list.
To do so, please perform the below steps:
1. Open Microsoft Security Essential program.
2. Click on Add button.
3. Select the path c:\program files\microsoft security essentials\MsMpEng.exe
4. Click ok.
5. Click on Save changes.
6. Close Microsoft Security Essential program.
7. Restart the computer.
After restarting the computer, please check the usage of MsMpEng.exe service in the Task manager window.

You've got Memory Management and Bad Pool Header errors - both are related to memory.
While I don't suspect that you have a RAM problem, it would be prudent to run MemTest and Prime95 to help assure us that the RAM/memory channels are working properly. The reason I don't suspect the RAM is because of the patterns within the error reports - it seems to be memory access issues rather than physical memory problems (so continue on with MvdB's suggestions).

Here's the full list of free diagnostics/stress tests. Just scroll down to the memory test and to Prime 95:
I suggest starting all troubleshooting with the following diagnostic tests. They'll save you a lot of time and heartache if there is a hardware failure, and you'll have the disks on hand in case you need them in the future:
H/W Diagnostics:
Please start by running these bootable hardware diagnostics:
Memory Diagnostics (read the details at the link)
HD Diagnostic (read the details at the link)

Also, please run one of these free, independent online malware scans to ensure that your current protection hasn't been compromised: Free Online AntiMalware Resources (read the details at the link)
Then, if the above tests pass, I'd try these free stress tests:
FurMark download site: FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net
FurMark Setup:
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature"
Click "Go" to start the test
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
NOTE: Set the alarm to go off at 90C. Then watch the system from that point on. If the system doesn't display a temperature, watch it constantly and turn it off at the first sign of video problems. DO NOT leave it it unmonitored, it can DAMAGE your video card!!!
- Click "Quit" to exit
Prime95 download site: Free Software - GIMPS
Prime95 Setup:
- extract the contents of the zip file to a location of your choice
- double click on the executable file
- select "Just stress testing"
- select the "Blend" test. If you've already run MemTest overnight please run the "Small FFTs" test instead. (run all 3 if you find a problem and note how long it takes to error out with each)
- "Number of torture test threads to run" should equal the number of CPU's times 2 (if you're using hyperthreading).
The easiest way to figure this out is to go to Task Manager...Performance tab - and see the number of boxes under CPU Usage History
Then run the test for 6 to 24 hours - or until you get errors (whichever comes first).
This won't necessarily crash the system - but check the output in the test window for errors.
The Test selection box and the stress.txt file describes what components that the program stresses.
More details on the use of this test: Torture test your CPU with Prime95
More Video Stress Tests:
1. Thanks to VirGnarus for finding this test:
2. Two other video stress tests (may be more stressful than FurMark):
Video Memory stress Test - МИ NVIDIA / Утилиты / VMT
Artifact Locator -
Sorry, but I don't read the language that this website is made in.
3. Another interesting test that came to my attention: Download - OCCT Website english
USE AT YOUR OWN RISK - the program doesn't have a whole bunch of safety features to protect you from yourself!

I can't c:\program files\microsoft security essentials\MsMpEng.exe but I did find c:\program files\microsoft security client\antimalware\MsMpEng.exe. Also checked in folder program files (x86), no luck either. Should I re-install it or get another free anti-virus program?

sorry, forgot to add that I added the process, c:\program files\microsoft security client\antimalware\MsMpEng.exe instead and don't see it in the Task Manager under Processes or Services tabs.

Just an update, I was able to borrow a couple of ram modules from a friend w/ the same secs as me 1600mhz DDR3 4gb. Checked in bios and it's currently running at auto -- 1333mhz, dual channel this time. Ran prime95 test for almost 24hrs until my son accidentally turned off the system ><. Anyways, so far the system has been stable for a day but that's the system being idle, no unusual crashes/bsods **crosses fingers**. I will start doing Memtest later and leave it overnight. I'll update when it's done.
