Xectuer 3 was working, then started getting the red and green flashing

I installed my Xecuter 3 about 3 months ago, installed the newest bios and slayers. Everything worked great...until this morning. I started the xbox up, and now all of a sudden it is giving me the blinking red and yellow death (only after rebooting 3 times)! However, if I press and hold the power button so the chip is deativated, it will boot the regular xbox dash, but also makes me enter the current time each time. Please guys, any ideas? This is really weird...

 

Check your install, it is usually due to something coming loose.
