My parents have a clear XBox fitted with an Xecuter 3 chip which has been working great for months now. However yesterday they turned on the XBox, the Xecuter light didn't light up, and then a green screen came up mentioning about a bios with options such as "Load BIOS from ..." and then gave options including HDD, disc, internet and another choice they can't remember. These options stayed on the screen for approx five seconds before the XBox shut down.
Now when they attempt to turn the XBox, it wont boot into the chip's mode. When you turn the chip's mode on, it'll switch on, the XBox turns on for a split second, then shuts down. It repeats this procedure, then on the third time it'll stay powered on, but with no LED on showing the modchip is on and the eject light continues to flash.
They can still boot into the standard XBox mode, which leads me to believe its a problem with the modchip somewhere. The XBox hasn't been moved since it was last working, so the chip hasn't been knocked at all. Any ideas would be appreciated!
