Greetings everyone!
Here is my situation:
First my Mac Pro G5 showed a blue screen every time I turned it on. It didn't go further.
Then after a check, I realised that the graphics card was dead. I replaced it and naw it works. (The card is an ATI X1900XT.) But still, when I turn on
the Machine, after the apple logo, the blue screen remains there for about 5 minutes, then I am able to log in. Allso when I log out it remains for 5
minutes. So far, in the system everything works perfectly, but what's with the blue screen!? Is it a software or hardware problem? I have reset the vram
and pram, but nothig changed. I have reinstalled the system OSX 10.6.3, allso got a new HDD and installed the OS there; no change. I changed the slot of
the graphics, the slot of rams; no change. Can someone tell me how to resolve this issue?

10.6.3 only runs on Intel Macs. It won't work on your G5.

You need 10.5 or earlier.

You either have PowerMac G5 or first batch of intel based Mac Pro. You can't have it both in one computer.
You either have to find Apple Service Diagnostic disk for your exact model or find Authorized Apple Service Provider to diagnose it for you.

I am sorry for the wrong model. It is a Mac Pro, Model ID: MacPro1.1, Model No: A1188 (EMC 2113). This Machine has worked for some years with 10.6.3. I only replaced the Graphics Card. No other changes are made!
