Does it had fan? check the fan if it spinning fine.. i'm kinda worried psu not supposed to make clicking sound.. u might wanna consider replace the psu.. InvalidError a b ) Power supply September 18, 2012 12:55:22 PM Is it a "tapping" or a "clicking" noise? For "tap", the only source I can think of is something touching a fan blade. Maybe one of the fan blades has something stuck on it or is out of alignment and is hitting something. For "click", the only thing I can think of is the disconnect relay but then your computer would turn off almost immediately as you hear it. Can't find your answer ? Ask !
