Yoiks!
Socket 1156 is ancient. My MOBO is a socket 1155 jobbie and that's really old. 1156 predates that. Current socket is 1151, prior to that it was 1150. I have been able to spot some socket 1155 CPUs in the wild, but they're still pretty expensive.
My honest advice would be to get a new MOBO and upgrade the CPU to a modern socket 1151 variant.
