Apr 13, 2013 1:50 PM in response to tymek2225by BDAqua,★HelpfulHi, 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...

Apr 13, 2013 2:03 PM in response to BDAquaby tymek2225,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.
