Re: Dell E172fpb
That behaviour is characteristic of a SMPS trying to start, shutting down on a fault, then starting over. Typical burp frequency is about 1 per second.
First two things I'd be doing, after a visual and ESR check of the usual suspects:
Check the rectified (ex line) DC on the large cap - should be around 1.4x line voltage. Check the small electros near the SMPS controller.
