Windows 7

For now I've installed everything you specified, except SP1.
I'll do that tomorrow and see if that will help.
I tried playing FIFA 12 today, after installing all these stuff, and BSOD again..
I uploaded only the latest BSOD in this post, which was IRQL LESS OR NOT EQUAL

No progress.
I installed SP1, and still have BSOD's.
Nothing of that helped.

Sometimes it is a process of elimination. We try to cover all the variables until the culprit is discovered. Although SP1 may not have cured your bsod it has made your system look a lot more like it should so some advance has been made already. Don't worry we'll get there...
Now looking through your dmp file I notice your running Daemon tools? Please un-install.

sptd.sys Wed Jan 04 00:01:58 2012: an sptd.sys variant from Daemon Tools (known issues with Win7)


Sorry about the lateness of posting, I've had some issue's of my own to deal with, namely a defective keyboard which was a tough one to find..

Ok, so I uninstalled Daemon Tools, and it didn't really help.
Here's dump file from that last BSOD after uninstallation of DT.

Code:

*** WARNING: Unable to verify timestamp for nvm62x64.sys
*** ERROR: Module load completed but symbols could not be loaded for nvm62x64.sys

nvm62x64.sys Fri Oct 17 22:01:06 2008: nVidia Ethernet Networking Driver (nForce chipset driver)

Please update your drivers: Drivers - Download NVIDIA Drivers

As I mentioned before please use your motherboard website as a guide and update all drivers to latest versions.

I installed those drivers with that link you gave me with nVidia Chipset:
(64bit)
NVIDIA DRIVERS 15.49WHQL

*Uploaded new dump file with latest BSOD (BSOD that happened after installation of these drivers).

As kemical has already noted above you need to remove this driver
sptd.sys 1/3/2012 Usually associated with Daemon Tools or Alcohol Software Products. Use the tool found here DuplexSecure - Downloads (get the correct version for your architecture) run it and click the UNINSTALL button.

I installed what kemical asked for, I uninstalled what Trouble said with the tool he posted.
I'm getting again BSOD.
I uploaded it as usual (latest BSOD, after removing sptd.sys).

Would you please use your Sytem's BIOS Utility to set your memory timings properly and see if that helps with the machine's stability
Currently your 400MHz memory which should be set to 5, 5, 5, 18, command rate 2T, is currently set as 266MHz memory 4, 4, 4, 12 command rate 2T
Please make those corrections and see if the problem persists.

I also noted several drivers in the driver stack of which I cannot find any trace of via google. Do you have anything other than the usual (mouse and keyboard) fitted to your machine? Don't forget, the more you can tell us the more we can help so info is key here...
