Original Xbox not reading discs

You can get a cheap DVD head cleaning kit. Put it in the XBOX, let is run for a while to clean the internal receiver, take it out.

Does it have the Red Ring of Death?

Common problem with the original xbox.

No but it will probably happened soon with the way that it won't play so many discs

Remember, that the original Xbox came out in 2001. It looks like (from not expert sites) several answers guess a console should last about 10 years with moderate use (whatever moderate use means). You might find it a bit too pricey to take it in for a professional cleaning at maybe a computer repair store (but at least you can ask for an estimate). It might be time to retire said console and maybe find a slightly newer one on Ebay?

The Xbox One came out in 2013? It's about time they come out with the next generation Xbox. But I digress.
