Clean the CD-ROM
Clean the CD-ROM. To do this, use a CD-ROM cleaning kit, or gently wipe the silver side of the CD-ROM with a soft, lint-free cotton cloth. Do not use paper cloth which can scratch the plastic and leave streaks. When you clean the CD-ROM, wipe from the center of the disc outward. Do not use a circular motion.
If the issue continues to occur, clean the CD-ROM with a damp cloth or a commercial CD cleaning solution. Dry the CD-ROM thoroughly before you insert it into the CD-ROM drive.
Clean the CD-ROM Drive
If cleaning the CD-ROM does not resolve the issue, clean the CD-ROM drive using a CD-ROM drive cleaning disc. CD-ROM drive cleaning discs are available in most computer stores.
