First thing I'd do is test the memory one stick at a time with memtest: http://www.memtest.org/
Or some similar pgm. Windows has its own built-in memory testing app, if you want to use it. If the memory tests OK...

Breadboard the system on an insulated surface with just the CPU/cooler, 1 stick of memory in 1st slot, PSU, and monitor connected to integrated video. Connect your HDD and boot to windows. You can start the system by shorting the 2 pins the start button connects to. (or plug the start button in) If it still BSODs, I would suspect a bad MB.
