Try a CD lens cleaner, make sure the CD is free from fingerprints and then change the CD drive. They do age and your post has comments that mimic what a person would write if the CD drive was aging (and failing.)
First off you should know I installed some new memory and a video card before this happened. But I have since took both out. So, here is the problem: I turn on the computer and windows won't load. It tells me that "system32/drives/ntfs.sys is corrupted or missing" I tried to run windows xp cd to repair the file but the cd won't load all the files. I've tried to load the cd a few times and it says dmboot.sys or dmio.sys and sometimes other files are corrupted and that it has to quit. The cd works fine on my other computer. any suggestions?
