Help needed please



Hi all
Not sure if I am posting in correct place if not please excuse my mistake. I am not fully computer literate so I am sorry to be a pain. I have recently purchased a Samsung SH S223C CD/DVDW for my computer. I installed it on the SATA drive as told and all worked fine for 2 weeks. On Mon this week I tried to burn a CD and low behold it would not work I then went to device manager checked and found an exclamation mark against the model I deleted and re installed and a message came up quote problem with installation your DVD player may! not work properly. I have searched for the DVD drive on my computer and it does not show I have tried to install again from the disc but again it will not reconise or show a DVD drive on My Computer any help would be most appreciated sorry.
