PLEASE SUPPLY RELEVANT INFORMATION:
Operating System Version: Linux
Problem Hardware Make & Model: AMD K6, generic hardware, 5 years old
Error Messages: None



Situation:
I plugged in the power cable after being away over Christmas break. Heard an loud pop/bang. Tried switching on and got CD ROM, Power, HD & lights. NO sounds (other than power & CPU fans). No signal to monitor.
Will not switch off unless the power switch is held in for 4 seconds.

Testing done:
Took out and tested voltage on bios battery, it is still good.
Tested output of power supply to CD ROM, HD Etc. The output voltages were as expected. I have a basic multimeter.

Explanation from other posts:
Short or blown capicitor. There was no evidence of this from a visual inspection of the top of the mother board. Have not checked underside of mother board or in power supply box (requires removal of mother board to get into).

Question:
What is the best of tracking down the source of the problem? (Other than paying someone who has fancy test gear and a good knowledge of the hot spots on a mother board)

Thanks in advance
Keith.

Working around finding the problem, since you have all the classic signs of a blown motherboard or blown CPU, the only right way is to buy a new motherboard and test that at first. Even if you could pinpoint which capacitor on the mobo has smoldered through, there's no way you can replace it.
