Bug Check 0x3B: SYSTEM_SERVICE_EXCEPTION
This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code.
A few things can cause this BSOD. Putting aside the highly unlikely possibility of the OS service actually being defective, the two main problems that can cause this tend to be either drivers or RAM.
0xC0000005: STATUS_ACCESS_VIOLATION, is one of the more common error codes. Long story short, it means that memory corruption has occured, and the application crashed as a result. Points again to either drivers or RAM.
In the short term, I would run memtest86/Prime95 to make sure your RAM passes OK.
