A computer would be nothing without its processor. The CPU/processor tells the hardware what to do in order to perform certain tasks. Since the CPU is always working, it needs a lot of power flowing to it, meaning it gets very hot. The change in temperature can cause the parts of the CPU to expand and contract, leaving a chance of disconnects between pieces that should be touching. Nerds on Call can repair or replace broken parts of the processor, or the entire CPU altogether to bring your computer back up to speed. One of the most common issues with CPUs is cooling them down, and the Nerds know how to maximize cooling for the most effective processing.
