How long will a refurbished XBox 360 last I mean Gamestop refurbished not a red ring of death one sent to Microsoft to get fixed but the kind someone would sell to Gamestop and they refurbish it?

It means the 360 has been over heated depending on what player slot it is over... it could also mena your power cord has died and a few others.

There isn't a set time. Mine took almost 2 years. It may never even happen for some people.

It does overheat but it wont get it just for being on. If you have it in a cool, well ventilated place it wont overheat quickly.

1 ring means a memory problem, if u have a harddrive replace it, or switch out memory cards if u use one, but it sucks u lose all your memory. U can also try unpluging all the cables and the power...

go to youtube at the top type in how to fix e74 and click the one that has the xbox on the brown shagg carpite do what it says and it sould fix it it fixed mine
