My Power Mac g3 Blue & White starts up, but I get no video.

I have an old powermac g3 b&w and when I turn it on, the lights go on, but I get no video on my screen. What should I do to get it working?

Hi, does it sound like it's starting up, like Disk activity & such?


Have you reseated the Graphic card?


Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

Thanks for your reply, yes, I can hear how it's starting. I had this PowerMac for a little time, and then (I think so) the psu was dead, but I had an other powermac (the same model) but it was not complete. I replaced some things to the other mac and now I get this what I described above. But the PRAM battery was not so good anymore, if I changed the date and time, it resetted it automaticly after restart to 1 jan. 1970.
