look like your Overclock is hitting a rough road huh? BSOD.... why dont you try backing down your cpu to 3.5 or 3.0 or even stock and see. I doubt its your powersupply. IT might just be your cpu not happy with running 4.1 or 4.0 ( its not a stable overclock afterall) It couldnt even pass 2 hours of prime. BTW, you really should find a speed where you can pass at least 4+ hours of prime and work your way up. instead of running at 4.1ghz and work your way DOWN to a stable speed.
