First suggestion is to do a basic test of the PSU and then a barebones set-up outside of the case, for the latter see my canned text below and for the PSU see the video @ Corsair Video FAQ: How to test a Corsair power supply here
Remove the MB and do a barebones set-up on a piece of cardboard (make sure it is larger than the MB) only connect the PSU, the GFX card, screen, 1 stick of Ram and the keyboard.
IF your MB doesn`t have a power test switch you will then need to short out the 2 power on pins on the MB header to get the PSU to activate, you can use a small flat bladed screwdriver or a paper clip bent into a U shape, this is perfectly safe if you do not touch anything else, the idea is to see if we can get a BIOS screen if you do you can then add one component at a time until you find the problem component, you must power down and remove the power cord from the wall before adding another component, second suggestion try a known working PSU, it is not unknown for new components to be bad, third suggestion try and loan an ordinary PCI graphics card (not pci-e) again to try and get a BIOS screen.
Other things worth checking include, if you used stand offs beneath the MB are they in the correct locations (only where there is a screw hole in the MB) otherwise the MB will short out, check for stray screws or bared wires for the same reason,
make sure the jumper cap that can be used for clearing the CMOS is not missing or on the wrong pins and finally try removing the CMOS battery for a few moments and then replace it, this will clear any possible bad MB settings.
Your aftermarket cooler, a very important thing I must make you aware of is that you do not need the additional heatsink and CPU fan and if you did use it you would void your CPU warranty both AMD and Intel are clear on this, see below;
This Limited Warranty shall be null and void if the AMD microprocessor which is the subject of this Limited Warranty is used with any heatsink/fan other than the one provided herewith.

If the build is still unstable outside of the case, remove the hyper evo 212 cooler and use the one AMD provided, clean off the old thermal paste from the top of the CPU (see guide here) reapply thermal paste if the stock cooler that was shipped with your CPU does not have a thermal pad pre applied and while still outside of the case test the hardware again.
Let us know how it goes and any questions along the way please post.
