My modded Xbox (Xecuter 2.6) recently started doing weird things. When I press the power button, it will turn on for a few seconds, then turn off for a few seconds, then turn on again for a few seconds, then eventually FRAG. While this happens, nothing shows up on the TV... even when I get the FRAG, nothing shows up... no error... nothing at all.

Is this a power supply problem or something else?

If I keep trying, it eventually will start up.

what are the lights doing on the front?

what colours are they?

Can you eject the dvd drive?

When the Xbox is powering on/off, they are green. When they stay on, it FRAGs (flashes red and green).

Yes, I can eject the drive.

I also noticed that if I turn off the modchip, the Xbox will boot, but eventually gets to an error screen, but that's probably because my hard drive is unlocked.

Nevermind... I figured out the problem. D0 pin must have come loose (Xapter solderless). I removed it, then reinserted it. Now it works fine.
