Maybe you could provide a little more information on what you've tried - what happens when you do have RAM installed? As much detail as you can go into.

I would remove the board from the case and try to boot it from the bench.

you must have a system speaker attached to the proper pins on the board in order to hear the (pass/fail) codes...

remove all the connectors from the case and after connecting all the power leads short the "start button" pins on the board to boot up...

the beep codes will tell you what if anything is wrong...
