'won't turn on'
what does that mean?
the data is on the harddrives.
So however it's stored, it will most likely still be there.
if the 'fans won't turn on' then you might have a bad power supply . . .
did you set all the plugs and connectors back in firmly?
fans don't turn on unless the bios is set up to do that. So it's possible you got a bias reset.
the one thing you absolutely DO not want to do is format a drive.
also if you added a very large new graphics card and fans don't turn on, it's possible that the power supply does not have enough power to give for the whole system.
as long as you have the harddrives, and they are in a format that you can use (IE not sure if you can do it with encrypted drives) you can just plug them into a different machine, that machine should discover them.
and then you'll have your data back.
do not, under any circumstance, 'install' to or reformat the drives you want to recover.
get a fresh drive and boot from that.
if it's a linux box and you lost the root password, there is a way to get it back.
but you need to be able to find that kind of thing on your own. No one is going to just tell you how to do it. (it's very easy, actually, but it takes a skill set that . . . is one of an expert system administrator.).
not turning on may merely mean that some case switch is triggered so that teh board shuts off if you remove the case?
do you have that kind of thing?
do you have a USB case you can stick the drives in? that way you could just attach them to a different computer. That is the quickest way to get back the data other than jsut realizing that a case switch needs to be disconnected.
I had a bad install with a new linux version recently. Never ignore rpm new messages when you are trying to upgrade and then down grade. I had to get the rpms and do it by hand like that and the DNS didn't work.
in the end I learned a lot.
