Hi you knowledgable people, a friend of mine in Canada has recently had PC problems that seem to be caused by humidity. Whenever the humidity is excessive, as it has been on several occasions recently, the computer just shuts down completely. Restarted it might run for a few minutes then close down again. Is this a problem anyone has come across and is there a practical solution?
Probably dust as wee eddie suggests, this could also provide a low impedance path on the logic board/cards when the dust gets damp and could cause all sorts of problems. I would suggest a good clean as wee eddie suggests and if practical/safe leave the pc switched on during periods of high humidity, heat from the machine will then help to keep logic dry.
