Discs will not play

i have a optiarc cvc ad-5540a and it has stopped playing some burned dvds most ligit dvds and it also will not read my bioshock game i just bought. i have an alienware that i have had for les than a year and i dont know what could be wrong. any ideas?

start with the simplistics and go from there. when was the last time you cleaned your drive? after that check your defrag status and device manager to run a troubleshoot. also try checking the disks out on a diff drive. might be the disks not the drive.

i have cleand the drive and my defrager said i do not need to defrag and the trubleshooter could not help me. :sad:
