System exception due to poor CPU socket contact

When the computer is in use, suddenly appear black screen and restart the situation, reboot, the computer or black screen. What the hell is going on here?

Because the CPU pins are gold plated, and the CPU sockets on the motherboard also need gold-plated, can be used well. Because the gold has a good conductivity, not easy to oxidize, so the CPU socket between the general will not encounter bad situation. But as the market price competition is fierce, many motherboard CPU sockets are not gold-plated, or gold-plated thickness does not meet the requirements. Therefore, in the use of the process, as the use of more and more long, CPU socket will easily produce oxide layer, so that the CPU and socket between the bad contact, resulting in computer crashes and other failures.

In this case, the user only needs to replace a cooling fan to tighten the CPU or replace the computer motherboard can be resolved.
