Sorry probably should have given you a little more info:
Xbox flashes red and green when it tries to boot up. It has 2-3 tries at booting and then just flashes.
your xbox is fragging which means that the Bios is messed up. You should try to reprogram yourX-chip with the latest bios v1.3. Your chip could also be fried or something. not to worry about the xbox though, most likely the reason it's not booting up is because you have upgraded the HDD? (not enough info). If ypou have upgradded the drive then the original xbox bios might have trouble for a number of reasons. 1st maybe you did not lock the new HDD that could be the problem. There are some other reason which I'd rather not get into until you give more info.
Try putting the original drive in and remove the chip. You shold be fine.
