Bad motherboard choice for that cpu.... in either case it needs the F3 bios for the cpu to work. (8350/8320/6300/6350)
Otherwise try these things first;
check power connections.
motherboard standoffs are correct, and extras that may be shorting out the motherboard are removed
ram is inserted in the correct slot/s and in far enough.
try another gpu in case of the 270 being DOA
That strange noise is most likely the board having a fit trying to supply enough juice to the hungry cpu. Be careful of the area around the cpu socket - it'll be crazy hot.
The board may not be able to supply enough power to both the cpu plus a pcie lane ~ hence it will boot without the gpu. Try the gpu in another system - if that doesnt work its DOA - so return it.
