take out your other hardware, network card, sound card, drives etc.

Its probably that one of these is faulty and causing the crashing. You've replaced the RAM, PSU and mobo so that pretty much rules out the primary culprits.
HAve you tried stress testing the CPU with something like Prime95?

I take it you've checked that the CPU is running at a good temperature?

Hello,

Can you boot into safe mode?

If you do get a chance to boot into the OS successfully, check to see if Automatic Restart is disabled, and if not, then disable it...
