Summary: After a lot of pain, I determined that the Gigabyte board was bad that I originally bought for an Intel Lynnfield i5 750 quad core. The RAM in one of the memory slots was destroyed and the slot would not work with any good substitute RAM. The LGA 1156 CPU socket & Mobo needed for the i5 Core 750 was out of production. I opted to replace the Mobo which was the least expensive way to go with Deal-Stop Price on Amazon. No experience with them but by far the best price.
