You might try getting some contact cleaner (I use a brand called 'Gold-Guard').
You remove the chip, spray a little on the socket contacts, and replace the
chip. While you have the chip out, take a close look at the socket itself to
make sure you don't have any crud in it, and that there are no 'compressed'
contacts. If you find compressed contacts, the best bet is to replace the
socket, either yourself, if you are up to it in skill level, or by a service
tech.

Next time this happens, try reseating only one chip at a time to see if you can
narrow it down. If the contact cleaner does not do the job, it might require a
chip replacement.
