An ultra 2 machine had a failed SMPS. So a new one was
procured. The new one has come ( Zytec EP071235-E 350 W )
and we fitted it. The machine booted up on turning ON the power.
after running it for 5 minutes and making changes in dfstab
and auto_home files ( the machines configuration need to
be changed ), the machine was powered OFF using the poweroff
command.
The trouble started here..
the machine could not be powered ON..
the familar power ON beep never comes now..

i wonder what must be wrong ?
how do i go about solving the problem..
one broot force method is the process of
elimination ..
to unpopulate all the cards, and memories
and try booting..
if power ON is possible continue till
it doesnt ?

However i would like to seek expert's view before that

the cards, memories and try booting

Is the green ligth on the front on ?? Did you check on the rear of the new PS fan is turning ? Did you plug the power cable from the new PS to the motherboard properly ?

If the fan on the new PS is not turning, you've another failed PS.
If it's turning and nothing happend, recheck the manual and see
if you plug the cables from the PS to the motherboard, Hard drive, CDROM ... is right. I don't think you'll need to remove the cards, memory. Check to make sure you plug the right cables
on the right spots on your motherboard.

Good luck,
