i just put in a sorta new motherboard and graphics card to my old micon millienia. I can hear the hard drives,(1 180 @7200 and 1 20 @7200) and the fans on the grpphics card, motherboard and case all start up. however the screen does not light up. It is recieving something from the computar, because if i unplug the computar the monitar tells me it is working and just needs input. also i hooked it up to this computar and it worked. what should i do!

thanks!

oh yeah, i forgot to say that it is a asrock mother board, k7v88 witha n athelion processor. i don't know what my old motherboard was, but it was a pentium 3

thanks again!

also should i have turned it on first with my old graphics card?

Try it with on-board video and sound, one stick of RAM, and one HD and see if it will come on then.

You might also look at the pins coming from the monitor to make sure that one of them is not bent.
