Clean it,

sounds like the CPU cooler is so clogged with dust it is over heating almost immediately. There are a number of videos on YouTube to show you how to do this.

My dell optiplex 280 will no longer boot but the cpu fan sounds like an aircraft taking off. I had this problem on and off and it usually came good after several reboots. No luck this time. Any clues

"usually came good after several reboots." is THE classic symptom of bad caps. You found it.
