1) Unplug and re-plug connectors. The wiping action will clean them.
2) (advanced) With the computer open but connected and running, hit
components and connectors one at a time with freeze spray and note the
appearance or disappearance of symptoms. This assumes you can get at
relevant bits without shorting anything inside. Freeze spray is
generally used to find defective semiconductors, but will help find
mechanical issues too (for example, a cracked solder joint).
