This is a summary of all of your reports. I will use this as my check list to suggest different courses of action for you to take.
Per the check list in this order (easy ones first)
1 Make this scan. If errors run several times SFC /SCANNOW Command - System File Checker
In device manager make sure that your video card and driver are up to date.
Stop the automatic defrag. The default is once a week.
Make sure there is sufficient space on your hard drive.
Unintall your anti virus and replace with Microsoft Security Essentials. Unistall your Firewall and use Windows Firewall. At least for test puporses so Anti Virus can be ruled out.
You said that your already checked memory
2 Test hard drive if not already done
3 Take the driver verifier test. Using Driver Verifier to identify issues with Drivers
Take one step at a time. After each step use the computer if the BSOD continues, try the next step. .
