[QUOTE="pigoo3, post: 1620960, member: 56379"] I think that the clicking sound is normal when it is unplugged & plugged in. If the clicking continued without unplugging…then I would suspect the power supply. The computer should not power on when plugging in the power cord (without pushing the power button). Again…it could be something to do with the power button. This is the obvious first thing to check.:) - Nick [/QUOTE]
