Memorex dvd ram 525g v1

hey i bought this dvd drive awhile back and i installed it it worked it played cds and dvds then when i installed my old cd drive with this one ,adn now this one dont play cds just dvds i took my cd player out to see if it hat some conflicts with my dvd still the same thing what happend and how can i fix this?

Sounds like a coincidence…most likely just a hardware failure. While the drive may just be dirty, most likely the CD laser has failed.
