Memory problems

I'm fairly pc literate, but I swear when it comes to repairing my own pc I kind of have some difficulties so please bear with me.

I just bought this pc and received it no Wednesday. Since using it, it has crashed 1-2 times every day. The common errors I gets are system_service_exception and pfn_list_corrupt and one that read memory_management.

From what I gathered it was either my drivers or my memory. So I ran a memory diagnostic test, and it came up with hardware problems both times but when I restarted my pc the first so that it would tell me the errors, my pc crashed immediately with a pfn_list_corrupt error. When I ran it a second time my PC started normally but nothing ever read off to me what the problem was.

I have an HP Pavillion Notebook and am using Windows 7 64-bit with 4 gb of RAM. Any ideas or troubleshooting I can do to better evaluate and fix this problem? I really need this notebook for college soon.

Also my pc is a refurbished pc from compusa

From Last Night:

My pc crashed again and this time the error was memory_management and the troubleshooting read this:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.
Locale ID: 1033

Additional information about the problem:
BCCode: 1a
BCP1: 0000000000041790
BCP2: FFFFFA80019D4180
BCP3: 0000000000000201
BCP4: 0000000000000000
OS Version: 6_1_7600
Service Pack: 0_0
Product: 768_1

I also forgot to mention that when I attempted to load the minidump files it wouldn't let me compress them, even after I took ownersihp


Please go to C:\Windows\Minidump

Copy the files in there to any other folder. Then zip them. Attach the zip to a post using the paperclip above where you type, in advanced mode reply.

We can see the stop errors like this.

I attempted to do that but the files won't allow me to. I even used the 'Take Ownership' command on them all. When I try to do so it comes up as 'file not found or no read permission'

Boot to safe mode + networking.

Then copy the files to another folder before zipping.

Attach from there.

I finally got the minidumps into a zipped file and attached them to this thread and will add them to my main post.


AVG is known for memory corruption crashes. Please uninstall it in safe mode using the special tool found here:

AV Uninstallers - Windows 7 Forums

I recommend MSE as a replacement as it never causes bsod and is resource friendly.


These drivers need to be updated.

That's the Intel storage driver. Please visit their site and let the scan utility find and install the latest drivers:

If for some reason it doesn't install the newest storage driver, you can get it from your motherboard's website, from the manufacturer.

These other drivers should be Googled to find what they are and to get the latest versions of them to instal. Manufacturer's sites always best:

Unless you plan to be very particular about updating them all, I'd suggest a clean install of Windows while performing a format during.

Thank you for the advice on AVG. I uninstalled it and installed Internet Suite Security instead (it came with a free year with my pc).

The drivers I have to call my manufacturer about because Intel did not recognize them properly and I'd like to see what they suggest as they didn't send me the Windows 7 discs or anything.

Thank you for all your help so far though!
