Hello, I was playing on the 360 last night and I noticed a really faint beeping noise that was constant and happened every half second. The beeping wasn't very high pitched, but it wasn't low either. I investigated and it turned out to be the Xbox. I made sure the hard drive was secure, which it already was, but then the beeping stopped for about a minute. I kept playing and it came back. Then I ejected the disc, and it stopped. I started playing again to see if that was the problem, and after about a minute it started again. Ejected the disk again, and it stopped again. Odd. The next day, or today, I try another hard drive with another game. The beeping noise is back, but this time is a bit louder and lower-pitched. I am not sure what to do about this, I don't want to open the console and void the warranty. I'm not even sure if I should worry about it. By the way, the Xbox is a White Pro I got in 2007 and all the games are installed to the hard drive, and the beeping noise isn't there with arcade games or demos if that helps. Any help or info is much appreciated.
