The Inq claims a gamer called Dan has found a way to fix his new Xbox 360 console from crashing every 20 minutes.
He fixed it be raising the power supply of the ground with some string.
Dan, from Duluth, or 'goldeneyemaster' as he is known, told the game spot forum here that he thinks the main reason that the xBox 360 freezes is because the power supply overheats. The solution is to lift the power supply off the floor and allow the air to circulate better around it.
Another simple method involved getting a box with no cover and putting the power supply on the edges.
