I have a 1.0 xbox with an x3 installed using the wire method. It has been installed and working great for over a month now. Yesterday, when I turned my xbox on, it fragged. So I popped the cover and started looking around. The 3.3v light (in the corner) is lit, but the 5v (next the dial) is off. I checked all connections. I checked all voltages on the tips of the wire install adapter and they read as follows:
1- .96
2- Ground
3- No pin
4- No pin
5- No pin
6- 5.04
7- 3.24
8- 3.24
9- 3.28
10- 3.24
11- 3.24
12- No pin
13- 3.27
14- 3.27
15- No Wire to pin
16- No pin
These match the list here http://www.xbox-scene.com/articles/lpc-diag.php, except pin 1, which I'm not sure how important that is, or even if my voltmeter is accurate enough to measure that low. I also measured these on the back of the x3 chip and they are all the same. I also checked the alternate 5v connection (for 1.6, not in use on mine) and the little solder pad on the back of the chip marked 5v and there is no voltage reading at all on either. I would think that these should be 5v as well, should it not?
I have searched and searched the forums looking for an answer and can't find anything. I've resoldered the wires twice (which seems redundant, as the voltages read fine on the tips). I've removed the reset/eject switch. I no longer have the pin header to try using that instead (anyone no where I could maybe order one, if it would even help anything?).
The xbox works fine with the chip disabled. Based on the lack of 5v on the alternate point on the chip, I am thinking maybe the chip is dead. Is there another 5v point on the board (1.0 xbox) that I could try attaching to try that? I can get a hold of a friends x3 and try that, but I don't want fry that one too if something is wrong with my xbox.
Thanks in advance for any help.

Edit for fix:
Turns out it was the modchip. A trace on the back of the chip next to the pin header plug solder points was somehow broken. I fixed it with a bit of wire/solder. Now everything is fabulous. Hope it lasts now. Thanks to anyone who pondered about what the problem could have been
