DVDs not working in my PC

This is probably a stupid question, but for some reason DVDs will no longer play in both my DVD players in my PC. I get an error saying that it does not detect anything. Is it because I have no DVD Playback software? I clicked on the drives and they show that nothing is in the drives. Please help, I know it’s something easy to fix.

I have the exact same problem with my half life 2 cd-dvd and my star wars battlefront 2 cd-dvd… since these are games I love, I really really need help.

also it may be because of my dvd drive and not the dvds, seeing as how those 2 are the only dvds I have.


AGH! some help please? look, it may be because this thread is old, so im making a new one.
