This is strange! I was playing Bejeweled 3 in my Xbox 360 and the gems were moving up and down by themselves. First, I thought that there might be problem with the controller. But I have checked with other games, did not face any problem.
Problem occurs only in Bejeweled game. Even though I did not touch left stick, the gems move.
What could be the problem?
I have been playing the game through a CD since a few years, is it possible that it is problem of the CD?
But there are other games too in the CD but they are working fine.
Help is appreciated.
