Why won't lenovo y50 laptop recognize external dvd CD USB drive or stay connected?

It keeps disconnecting and reconnecting by making those beeping sounds? Also, sometimes it shows up on my laptop and sometimes it doesn't; if it does it just disappears…

The DVD drive itself keeps making the same repetitive spinning sounds but laptop won't recognize it. It does all this depending on different USB cables I use, but never actually is recognized or stays connected!

Help! I can't load games. Its a 2014 lenovo y50 gaming laptop with the external DVD cd drive. This is built for games yet it won't recognize the drive!

Why is this brand new laptop not letting me use the USB dvd drive?

Wrong USB port. Might be trying a USB 3 port and USB 2 device or vice versa.
Lack of proper driver for that drive.
Best guess from no info on your make, model, and Windows version (w10?).
