Random BSOD Page_Fault_In_Nonpaged_Area BugCheck 50

This has become really annoying. It was very infrequent at first, but I had to reinstall Windows 7 (64-bit) when BSOD with this error started appearing right after the system had booted. For about a day or a two there were no BSODs, but it has started happening again.

Please help.
Here's the analysis of the dump file on WinDbg:
