Sony VGN-NR398E Cpu

The quickness and speed of your laptop largely depends on the clock speed and model of CPU installed in the system. The CPU is the main hardware component that processes information for the computer. In order to replace the old processor with a new CPU in your Sony VGN-NR398E, do some research as to how to do it properly so you do not wreck the new processor. You should make sure you are replacing the component that is actually bad, as a CPU rarely goes out unless it was overused or overclocked. Buying and installing a new CPU can be tricky for anyone to do themselves, as there are a lot of things that could go bad.
