BSODs while playing battlefield 3, randomly and idle

Hi,
I've been getting many BSOD's recently, theyre occuring randomly, when PC is idle or lots of them when playing battlefield 3 (those have been reduced significantly by increasing GPU fan speed to manual 70%).
I've tried:
Cleaning up registry
Cleaning up HDD
Reinstalling GPU drivers with driver sweeper
Swapping out RAM and cleaning it up
Run Furmark stress test - 15 minutes max perf. whole test, no errors
Used win memory check tool - no errors


My Rig:
CPU: AMD Athlon II X4 630 2.8 GHz
GPU: Radeon HD 5850 1 GB
RAM: 4 GB RAM DDR3 (4 modules)
MB: M4A78-EM
PSU: Arctic Cooling Fusion 550
OS: Win 7 Ultimate x64

My PC is cca 2 years old, its currently running on defaults clocks (everything)

Most of my BSOD's are SYSTEM_SERVICE_EXCEPTION but I've had many others such as:
BSOD REFERENCE_BY_POINTER
BSOD BAD_POOL_HEADER
BSOD BAD_POOL_CALLER
BSOD irql_not_less_or_equal
BSOD page_fault_in_nonpaged_area
BSOD driver irql_not_less_or_equal
BSOD MEMORY MANAGEMENT

Also, this is what I am getting after win restarts after BSOD (this one is most recent, previous ones looks very similiar)...

Recommendations

Problem Devices

Code:

AODDriver4.1    ROOT\LEGACY_AODDRIVER4.1\0000    This device is not present, is not working properly, or does not have all its drivers installed.

Please install the drivers for this device. Devices without drivers can cause issues.


Daemon Tools
Please uninstall DAEMON Tools. This software uses a driver called sptd.sys which is a known BSOD cause in Windows 7. Uninstall the software using Add/Remove Programs. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

As an alternative, many people recommend the use of Total Mounter or Magic ISO


System Optimisers
Please remove the following software

Code:

Auslogics BoostSpeed

This software is a known cause of BSOD's. Most people here do not recommend the use of automatic optimisation tools for Windows 7. Microsoft have improved Windows 7 significantly and it is much better at organising and optimising itself than its predecessors. Windows 7 is not XP. Automated optimisation software can delete important registry entries that can cause multiple problems with windows 7.

If you feel the need to use a registry cleaning or optimisation software, I recommend the use of CCleaner but make sure you back up the registry before making letting ccleaner delete anything.
I also recommend the use of Puran Defrag to defragment your HDD. Check the "Boost Overall System Speed By Puran Intelligent Optimizer (PIZOR) under additional operations.


Razer Mice
Razer Mice can cause issues. Please resort to using a traditional USB mouse for testing if possible.


BSOD Analysis
The BSOD dumps you gave me do not give a definitive cause for your BSOD's.

As a result I recommend you check your hardware for issues. Please run Memtest86+ to check your RAM. Let it run for 6-8 passes overnight as described in the tutorial. Pay particular attention to parts 2 and 3.

Also check your HDD for errors using Seatools and chkdsk.. Download and create a bootable version of the Seatools for DOS program as described here. For check disk, follow this tutorial: Disk Check
