Try physically removing the component, check for dust / hair on the contacts. Then re-install. I've had a similar problem with a video card installation on an m17x. One of my wife's hairs made it into the contact bar. Sometimes the simplest solutions are the best. Also, make sure you are grounded! When the case is open, it is no longer a faraday cage, and several thousand volts of static electricity can be transferred to the motherboard without you ever knowing, especially in low humidity conditions.
