DVD drive has been corrupted and no longer works

I just purchased this Gateway dx series desk top computer and was downloading information disk for my printer and external hard drives . Everything was going great until I downloaded my kodak camera disk . When I restarted my computer the information from Kodak came up in about 4 different windows . After closing the windows I tried installing my printer disk and got no response at all. I checked my "hardware" and the DVD rom drive was no longer registering on my computer. I ran a systems check and it said ; 'DVD rom drive has been corrupted' . I tried to get it back on by using the recovery disk but I got no response . I tried down loading the hard drive recovery but nothing happened ...
