Let start by taking the most obvious causes of BSOD out of the loop
Based on the dmps and the logs and your system settings here is my analyses.
1. Most of the BSOD has access violation error usually a sign of problem with accessing the memory... so please do a memtest
for at least 6-8 passes
for each RAM
at each slot
.. this is going to take long and better do it overnight.... You might have done this before... but i would prefer you do this for each stick at each slot for 6 - 8 passes...
2. You bios has updates....Your current version is F4 and the once available is F5A
. Please update this.
3. In your logs , precursor to your bsod..... you have these entries... these are caused by you Logitech Gaming Keyboard G510 drivers.... . which has know issues with Windows 7 and causes of BSOD.... Please uninstall ....i repeat please uninstall all the software and drivers related to Logitech
.... If possible after you do this ... use a normal keyboard... till we finish troubleshooting
The driver \Driver\WUDFRd failed to load for the device Root\SIDESHOW\0000.
The UMDF reflector was unable to complete startup because the WUDFPf service was not found. This service may be started later during boot, at which point Windows will attempt to start the device again.
The driver \Driver\WUDFRd failed to load for the device Root\SIDESHOW\0001.
4. I am not sure you removed the ATI drivers....prior to the installation of the Nvidia cards and drives...as there are remnants of the ATI Fuel service and drivers.......I would suggest you use revo uninstaller or iobit uninstaller to completely remove it....
Do these and let me know
