I'm trying to fix a friends computer. The OS is W98 There are some problems with the CD-ROM drive. When you put in a CD, it never autoplays (autoplay is enabled). I can "Explore" the CD and some CDs open fine that way. But other CDs (they're not corrupt, because they work on another computer), when I try and open the Setup or Autoplay file, I get a "This program has performed an illegal operation message" and the CD won't play. I can't figure out why.
