BSOD - intermittent . Seems to happen with multiple processes.

I have already completely replaced the RAM sticks as well. I ran mem tests on the originals with no errors but thought why not.

This one was code 0x000000C2

Code:

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff80002c9273a, The address that the exception occurred at
Arg3: fffff8800805b938, Exception Record Address
Arg4: fffff8800805b190, Context Record Address
