Having problems with your Dell Dimension 5150 (DIM515MIN) PC Desktop ?

My Dell Dimension 5150 fails to turn on when i press the main power button. It makes a jarring noise about five times and then nothing, no connection with the monitor, no activity. Any ideas?


Answers :

My first inclination would be to check the power supply. There is a fan within it. If it is not turning and pushing out air, the supply will immediately fail when it gets hot. Upon starting PC, you should hear that fan and feel air coming from the vent holes. I would also check to see that any case fans inside are clear of cables. Hard drives and other media drives could also make the sound, but they shouldn't prevent PC from starting.
