Building a personal computer requires taking into account many things, but especially the compatibility of the motherboard and CPU. A 775 motherboard is a good example of how the motherboard informs what CPU a given computer can use. The name refers to the 775 socket on the motherboard. This is where the CPU slots in to provide the primary “brains” of the computer, and each kind supports specific chipsets.
The 775 socket in particular supports a range of Intel processors. Various models of motherboard with the socket are available on eBay. Build or repair your computer successfully with an appropriate 775 motherboard.
