Windows 7: ASUS CM5571 - Random Blue Screen Memory dump problem

ASUS CM5571 - Random Blue Screen Memory dump problem

Hi Guys,
I'm new here. Bought this ASUS CM5571 6 months ago and like it a lot, except when every once in a while crashes , blue memory dump screen comes up for a few seconds ... not enough time to read the whole page.
Restarts... windows 7 finds no online solution for the problem. That's how I got here.
The crash is random. Sometimes nothing for weeks, sometimes 2-3 times a day. Little frustrating. I have another same model at my workplace with the same symptoms.

I attached the minidump.rar file for those who can read it....
Thanks for any help in advance

I don't know how to insert specifications from my profile here. Sorry!

You got lucky! Usually uploading just one minidump will result in a request for the rest of them (in the C:\Windows\Minidump folder). But it appears that the single minidump has identified the culprit.

It blames L1E62x64.sys - a driver component of your Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (NDIS6.20). It's most likely a driver problem, so let's try to remedy that first....

First, go to this link and download the driver under the "LAN" heading: ASUSTeK Computer Inc.-Support- It's the one that's labeled " Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller V1.0.0.37 for Windows 32/64 bit XP(WHQL). "
Then, uninstall your current drivers using Control Panel...Programs...Uninstall a program
Then install the freshly downloaded drivers and monitor for further BSOD's.

Here's a summary of the BSOD:
Built by: 7600.16539.amd64fre.win7_gdr.100226-1909

*** WARNING: Unable to verify timestamp for L1E62x64.sys

Hello usasma,
First of all thanks for your time and help!
I did follow your recommendation with a little change. Meaning :

1. I visited : ASUSTeK Computer Inc.-Support- and downloaded the file what I found under the expandable LAN section.

2. "Then, uninstall your current drivers using Control Panel...Programs...Uninstall a program" I did not find this entry in the Programs and Features section so I went to Start->Computer(right click)->Manage-> In the Computer Management window picked Device Manager->Network Adapters-> Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller( right click) ->Uninstall

3. Unpack -> Read the Readme file in Lan folder. Run setup.exe it lead me to this error message :

4. Not having internet because of the removed LAN controller I rolled back my system to a previous working stage. Start-> All Programs->Accessories->System Tools->System Restore

What else can I try? What did I miss?

Open up Device Manager and expand the Network Adapters category
What does it say there?
Right click on the device and select Properties, then the Details tab
In the dropdown box, select Hardware ID.
Let us know the 4 characters immediately after the VEN_ and the 4 characters immediately after the DEV_
We'll look them up online and see what exact adapter you have.

The screen shot says that you have an AR8121/AR8113 PCI-E Ethernet Controller made by Atheros
That is exactly the card that you downloaded drivers for.
Therefore, there's likely to be an issue with the card itself.

I would suggest purchasing an ethernet card that you can return. They're fairly cheap at most retailers - around $15 (US). If the system is under warranty, I'd suggest having it repaired that way.

I'm not really familiar with the hardware parts unfortunately, but what you are basically suggest that the ethernet card (Brand name : Atheros) is physically damaged and needs to be repared. This is a 6 months old computer and this sympthome goes back to the very first day I bought it. :-( I'll contact Asus and will see what I can do. Otherwise just walk to a computer store and ask for a ethernet card?
It crashed on me again mulitiple times since yesterday. I attached the dump file for verification.

6 months old? Yes, it's still under warranty if purchased new.

You'll have to look in the case to see what kind of slots that you have (unless the store is close and has a return policy).

PCI slot: Conventional PCI - Wikipedia, the free encyclopedia
PCI-E slot: PCI Express - Wikipedia, the free encyclopedia (compares to PCI in the picture)

You won't believe what happened yesterday. My computer knee down...I have no idea whether these things are related, but I was installing Quick books 2010 Pro updates went left it alone, used my other computer. Once without asking I could here it restarts.. .I thought - naively - it restarted automatically because of the updates. C Drive Disappeared. OOOOuuuuuch!!!!!
Inserted the boot media Device for repairing the boot sector.It did managed it somehow.( Not even Norton ghost 15.0 found the C destination drive to restore your drive!!!!!) I was able to get into safe mood. Deleted the temporary files I knew about. Started normal mode after that... look everything normal again... I had the C drive OS . Started my outpost internet security suite for deep scanning viruses. It stuck at the temprorary folder what quickbooks created for the upload. So it got suspicious. Tried to get into that temp folder to see what's up and delete the content possibly and stopping the virusscan. Freeze! Cold boot by the power botton...
BIOS sees it , but right know only black screen and asks for the right media device and Ctrl+Alt+Del
Googled the problem it is not hardware related ... I mean....the motherboard and the hard drive don't talk anymore...
Any recommendation? Start a new thred possibly?
