Hi guys a few months ago i had some BSOD issues after a while i pretty much gave up due to having funds for a new and better build (no issues with that) but no i could do with having this system working so i backed up all stuff i needed and did a fresh install of windows 7. all was fine for 2 days but then the bsod have come back.

PC Specs:
Windows 7 32Bit
MSI 760GM P23 (fx)
AMD Ahtlom ii x2 (255)
Generic 2GB DDR3 ram 1333
Nvidia GeForce GT610
1TB Seagate HDD
No cd rom or external cards

Now WhoCrashed is listing no hardware faults only drivers but i did run memtest for about 6-7 hours last night with no fault results

the drivers listed are:
rt86win7.sys (Realtek 8101E/8168/8169 NDIS 6.20 32-bit Driver , Realtek )
nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 340.52 , NVIDIA Corporation)
aswmonflt.sys (avast! File System Minifilter for Windows 2003/Vista, AVAST Software)
aswsp.sys (avast! self protection module, AVAST Software)
ntkrnlpa.exe

Now i know what all the drivers are (apart from the last one) but am not to savvy on updating them. windows says they are up to date and realtek, nvidia, avast all say they are up to date so am i missing something.

ntkrnlpa.exe?? a google search shows a system32 file but ive no clue on how to solve it
Minidumps can be uploaded if needed and driver verifier will be running once this is posted
any help would be welcome!

i have tried that apart from with avast ones since that was installed today. so that doesn't seem to be the issue
 
nvidia gpu also installs nvidia streaming software with it. The streaming software depends on updated ethernet networking drivers and will break the nvidia code if there are bugs in the network driver. Problem is only the chip vendor provides fixes for the network driver and microsoft does not update that file with windows update.

You want to go to the realnetwork website and update the driver

http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false

a old network driver can also breaks some types of antivirus scanning

ntkrnlpa.exe this is the version of the Windows NT operating system kernel that you are running.
(there are 4 versions depending on your CPU) It is the Core of windows and will be talking to all the device drivers. If something goes wrong you get a bugcheck in the device driver or in the kernel file.
If you are doing your windows updates microsoft fixes the kernel file very fast and the problem will most likely be in the driver that is calling functions in the kernel. Things like asking for memory, freeing memory but using it after it has been freed back to the system will result in the kernel bugchecking. (not the kernel's fault, it is the device driver that called the kernel that is the cause)

il do that and see if the stops the nvidia and avast crashes and let you know if or when i have another crash.
 
dxgkrnl.sys maybe causing a crash too. This belongs to Directx. I would uninstall Avast for now, then use its removal. tool. To rule it out

I would also uninstall AMD overdrive. AODDriver2.sys belongs to it. This is a known cause of crashes

And it looks like you had an AMD videocard?? Did you uninstall the drivers for this since you're using a Nvidia card now

i have always had this 610GT nvidia card installed. but i assume the AMD video drivers are the on board vga linked with catalyst which was download from the MSI website. and also no idea about the AMD overdrive. could it be tied in with a chipset/bios update from the msi site? sicne i havent install overdrive in a stand alone installer.

i have all windows updates installed so would of thought Directx to be directx11 and up to date but il try a manual update of that now.

EDIT:
Just tried to install directx 11.1 from the Microsoft site and it says that it is already installed.
 
get rid of this driver
C:\Program Files\ATI Technologies\ATI.ACE\Fuel\i386\AODDriver2.sys Mon Sep 05 22:02:55 2011

looks like the nvidia drive ended up trying to free a bad address and verifier flags on special pool caused a bugcheck. You need to do a change your dump type from a mini dump to a kernel dump or the data is not saved.

i've removed that.

on the system failure options it was already set to kernel memory dump. should i leave it, change to complete memory dump? or am i just in the wrong place to change the settings?
 
the bugcheck was from the nvidia video driver
while runing windows DWM.exe

I would make sure that you have all the windows updates applied to the windows service pack
(make sure they are not getting blocked)

I would also suspect this file and look for a update
\SystemRoot\system32\DRIVERS\AtiPcie.sys Wed Mar 10 06:33:41 2010

the newer graphics drivers tend to expose bugs in old driver code. there have been various bugs in DWM.exe that have been fixed over the years and are in the windows update fixes.
Apply the windows udates

there is 8 updates that wont seem to install 3 relate to remote desktops issues so no affect on graphics the other 5 are security updates, i have tried manual downloads also but just wont install.

All other windows updates and sp1 have been installed apart from optional language packs
