The most hated Xbox 1 Ring Of Death usually happens with your Xbox 360 freezes and when you go to restart it, you got a 1 ring that flashes in the lower-right quadrant. This is also known as the E74 error, which will display on the screen.
When you get the Xbox 1 Ring of Death, it usually means there is something wrong with your hard drive. The connection could be loose or worse corrupted. Don’t fret, I’ve had this happen to me many times and was able to fix it in under an hour.
The problem with the Xbox 1 ring of death or E74 error is that it is not covered by Microsoft warranty. That’s the bad news. The good news is that since it’s just the bottom right quadrant and just 1 ring, it’s not the RROD. The Red Ring Of Death is when you have 3 red flashing lights.
To see if it’s your hard drive problem, remove the hard drive and then turn on the Xbox 360. If the red light is no longer there, the problem is most likely the hard drive. The problem could also stem from another internal issue if the red light is still there.
