Event 41's simply mean that the system is shutting down - and Windows doesn't know why.
This means (IMO) that 3rd party programs and Windows stuff is ruled out - leaving hardware as the cause.
Prime95 failing on the Blend test indicates (to me) that it's a memory problem. Either RAM, CPU cache, or the memory controller. That's why I requested that you run the small FFT's, large FFT's, and Blend test. Running them together keeps the consistency of error reporting more constant (which is essential if we're trying to decide what's at fault).
