I've just replaced the video card on my 24" Intel iMac from a NVIDIA 7600 GT (256MB) to a NVIDIA 7600 GT (128MB). The shop that ordered and replaced the video card for me said that the 256MB was on a 3 month back order and was leaning towards discontinue. So the 128MB card was all I could get as a replacement. Also upgraded from 2GB ram to 3GB. After repairs I attempted to install Windows XP SP2 retail using Bootcamp from MAC OS X 10.6.2. I was able to create the partition "Bootcamp" followed instructions and proceeded to insert the Windows XP SP2 retail CD as prompted. Bootcamp did its usual restarting phase but then it just gets stuck and all I get is a black screen. I can hear the computer reading the CD and doing its normal windows set up procedures but I'm unable to see anything on my screen. After a long waiting period of about 30 minutes I just reboot the machine and hold down the Option key to boot back to Mac OS X. I does show me that I have Windows XP as an option to boot to. I have choose it and it leads me back to the black screen. I have installed and ran Windows XP using Bootcamp many times in the past, and have never had this issue as well. I've read many threads here and on other forums, but couldn't find the answer. If any of you know the remedy to this specific situation please help me out. If you need anymore information please ask as well.
