I have two home built pcs that both will not power on.  They both have worked for a least 3 years until now.  Both exhibit the same symptoms---both will not turn back on.  I swapped out the power supplies and they both will turn on for one second and then immediately cut off.  I have a biostar motherboard in one and I do not remember the other MB.  I tried a 2 different power supplies in these PCs.  Could it be both boards are bad?

If you have switched the power supplies and the computer will not load it sounds like a issue with the mother board.

...or an issue with PSUs he is trying to use.

 

To properly pinpoint...you need a known good working system...or a known good working PSU.  I see no mention of either in this topic.

Reseat the RAM. If it does the same thing, take out all the RAM completely and see what happens. If it stays on and makes a series of beeps, possible RAM issue. If still just powers on for a second and turns off, make sure you are positively using a good PSU. If you are certain you are using a good PSU, it may be a bad board. Also, check and see if there are any blown capacitors on the motherboard. Do a google search on what blown caps look like; they are usualy bad if they are buldged out and or leaking liquid.
