Hi, I have a problem where every time I insert a CD into my cdrom drive I receive an illegal operation.. An invalid page fault in module autorun.exe at 0167:00404500. I have ruled out memory hardware because I can use all programs on the hard drive/surf the internet etc.. No problems booting up at all. When I place a cd in the drive (Mitsubishi 52x IDE)It attempts to autorun, I then receive the illegal operation. This error can cause the system to be unstable (I have to restart the machine) eveything is fine until i use the cdrom. System specs as follows:- Pentium III 600B Slot 1. Abit VA6 Motherboard, 128mb PC-133 SDRAM, 32mb TNT2 Video Card, 15GB Seagate HDD, 52x Mitsubishi CDROM Drive, Thats basically it. There are no DOS Drivers installed for the CDROM... Any info/help much appreciated. Cheers, Steve
