Hi, new comer with support need here please:
I have a desktop with below configuration:
MB: Gigabyte EP35-DS3 Rev. 2.1
RAM: A-Data DDR2 800 1GB X4 (total 4GB)
Video Card: Colorful iGame HD4850 512MB PCI-E
Monitor: Samsung 943BWX DVI
I'm trying to change to Mac OS from Windows XP
I tried many time to install Mac OS on it, iTkos, iDeneb, Leopard, Snow Leopard, etc...........Unluckly I still failed to install it. There's always different error.

Anyone has same configuration and installed Mac OS on it smoothly? please kindly share your experience with me, many thanks!!!!!!!!
