Startup Blue Screens

[W0LF0S]

Windows 7 x64 Home Premium.

I have a problem with startup. Here's what typically happens:

1. BIOS runs it's startup.
2. Windows begins starting.
3. Login screen opens.
4. Blue screen (this sometimes happens as #3 and not #4).

The blue lists PAGE_FAULT_IN_NON_PAGED_AREA, or SYSTEM_SERVICE_EXCEPTION, no reason at all. After running Startup Repair, the problem seems to be fixed, and then comes back. I opened the Startup Repair log this last time after running the System Restore again, and the Root Cause it listed was: Unknown Bugcheck: Bugcheck 3b. Parameters = 0x0000005, 0xfffff80002fa7000, 0xfffff880061f2f90, 0x0.

I'm at a total loss as to what to do, any help at will be appreciated. Thanks.
