Sounds like you might not have the CPU fan plugged in.
I have a water cooled system and I dont have a fan for the cpu and trying to fill the system after doing a refurb to the rig I forgot to prime the system before filling it. The CPU got extremly hot and after I got the water flowing it kept shutting down. I let it set for 24 hours and it still did the same thing. So in my best guesstimation I FRIED like an egg the CPU.
Well after looking at the passmark I decided to go with the i7 2700k from amazon. I got it for 40 dollars cheaper than what newegg was selling it at. I also am going to prime my cooler this time outside of the rig and then I will finish filling the system.
Well this is what it looked like before...

This is what it looks like now ... minus the screwed up CPU and some other alterations.

So as soon as I can get the new CPU you will see the infamous LawnDart back online.
