Files that help describe the problem:
I am now seriously considering doing a fresh install of windows 7 on my C: drive partition. I just want to verify with you guys that the aforementioned stop error does not point to memory sticks or hardware in general.

I'm currently running a memtest on the 2x2GB sticks that are currently installed. I have already tested them the other day on a per-stick basis and they passed, so this is just to double check.

Please let me know what you guys find out on the attached dump. thanks!

After just 1 pass, memtest found errors!!! I'm not sure what to do next though. Not sure if I would retest the memory sticks 1-by-1 or just bring them to the shop.

Retest them one at a time, hoping you can identify whether it is a bad stick, motherboard slot, or compatibility issue.

Also, take a known good stick and test that stick in each slot.

I retested the first 2 slots with another set of dual channel sticks. The sad thing is that there are errors too. This could be a motherboard slot issue. So now I am retesting but now placing the sticks on slots 3 & 4 and seeing if errors creep up.

BTW, any news on the latest dump that I uploaded?

The last DMP you upload is stop code 1A which is memory management. MsMpEng.exe was the process running at the time of crash. It belongs to Microsoft window defender and probably not the cause.

BugCheck 1A, {3452, 95c3000, fffff700010ced90, d2100000a4b5fc46}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+33a23 )

Hmm... I'm sure I disabled it back when I installed Avast. Yesterday, I removed my Avast and replaced it with the MS Security Essentials. Not sure though if that enabled defender.

If it's a software related issue, the weird thing is I might also be having some motherboard issues too. So far mem slots 3 & 4 are working fine after about an hour of memtest. As for slots 1 & 2, it doesnt even last 10 mins before errors come out.

BTW, thanks for the continued help guys.

Sure, you are welcome

For your question regarding Microsoft security essential and the window defender. When you install MSE, it will automatically use the Microsoft Window Defender as part of its services.

Let's us know if using slot 3 and 4 completely solving the issue

Also, can you please perform system file check:
SFC /SCANNOW Command - System File Checker

I'm sorry if you've done this before

Let us know the result

You may try RMAing the motherboard, seeing as you are getting errors.

Yeah. I'll RMA the mobo tomorrow...

Really? MSE still uses defender? weird...
Once I finish memtesting the slots/sticks, I'll try to do a normal boot while using only slots 3 & 4 and do another SFC /SCANNOW and also check for stability while playing.
