Windows 7: Intermittent BSOD Issue

Hello I have a consistent BSOD problem which usually only strikes about once a week and sometimes up to 2 weeks. Usually I have been playing a game for about an hour or so before it happens. Have not been able to determine any consistencies in regards to what triggers it. I've attempted to update all drivers and debugging tools can never seem to pinpoint a driver issue (although that may just be me). Thank you.

64 bit Windows 7 Ultimate Full Retail
This is the original installed OS on the system
System is only about 2 years old
The OS was installed on 1/9/2011

Hi.

In this order,


Restart,run SFC /SCANNOW Command - System File Checker you may need to run it 2-3 times to "fix" everything.

Download and install SUPERAntiSpyware.com - Downloading File


Restart in safe mode run full scan with superantispyware.


Run RAM - Test with Memtest86+


Finish and post back with results.

1) ran the system file checker 3 times and found no discrepencies

2) booted into safemode and ran superantispyware/malwarebytes/spybot with nothing found except tracking cookies.

will run memtest overnight as I need to use the computer for work at this time. I will report back. thank you.

Ran memtest86 overnight and it came back with no errors.

can anyone see any noticeable driver issues or recommend any new course of action? thank you as always.
