Out of the 4 dumps provided, none had signs of Verifier running. Please enable it: Using Driver Verifier to identify issues with Drivers
Three pointed to the NT Kernel as the cause, which means that either hardware is the cause, or control was passed to the kernel before it bluescreened.
One pointed to your Intel graphics drivers. They are dated pre-Windows 7 RTM, which means they are technically not compatible with Windows 7. You should be able to find an update, which will hopefully take care of the problem.
Code:
igdkmd32.sys Wed May 06 14:13:40 2009
In summary, enable verifier and update your Intel graphics drivers.
