The following machine starts with a black screen saying that the fan is not work and will shut down in 5 seconds unless f2 is hit. while this occurs the fan is running fine. however if i hit f2 the os loads but the fan cuts out. Do i need a replacement of is it another problem that is controlling the fan because its strange that it comes on shortly and works fine. if checked the wire and the connection to the mother board and they are fine. any help would be great.
