The only thing I can think of is it may be the ram because the motherboard accepts upto 2x2gb of 1.5v ddr3 800/1066(oc) ram. The ram I have is 2x4gb of 1.65v ddr3 1600 ram
I think you are on to something, but not in the way you think
That mushkin ram probably has an xmp profile of 1600 @ 1.65 volts(overclock), but is really only 1333 ram.
That being said, it sould like a compatibiltiy issue with the ram. Check the test reports and get some tested ram and I'm thinking it will boot.
You can also try a full cmos clear >>Clear CMOS Guide<<
Then try to boot again with just 1 stick of that ram in the dimm closest to the cpu.
