What does this mean? <windows root>system32.dll. I am trying to install windows xp full version on to my newly built computer. That comes up after i install in on the blue screen and when it reboots to finnish the installation, it tries to log on and that thing comes up on the black screen and tells me to reinstall it cause it is a corrupt file. I do it about 5 times and the same thing keeps comming back up, should I have used FAT instead of NTFS? I dont know what is going on.
