I have elliminated Power supply as the problem by throwing the MoBo into my known good xbox and the fault remains.
I beleive the problem arose after too many resolders at the front panel resistors when trying to make my aladdin work (even tho it turned out it wasnt the prob).
So I retouched all surrounding resistors and capacitors just lightly with a little new solder and the problem remains. The mobo and cpu temps are normal, mobo at 30-40d cel, CPU @ 35-50d cel.
The problem seems to have progressed as it used to play games for a while and then shut off, but now it lasts only a minute or two.
Im sure it must be related to the fact that it turns on automatically with power applied. But I dont know where else to look.
Any help would be very much appreciated.

1) the solder is touching the metal sheilding and is ground it
2) You soldered to the wrong point.
3) Make sure you check the solder points, and make sure that the wire is only touch pin 8, and not anything else.

Any other possible solutions? I thought I was the only one with this problem.....

I think that the power button must be getting grounded as nfs911 says, but cant find where. BUT DAM he's got a cool case!!! (nfs911) That neon light in a clear case is fkn wicked. Im gonna get me one!
Good luck guys.
boo.

Now it starts up when i insert the powercord and initially stays on for about 20 minutes before its starting to turn on - off -on - off again.. And the power switch has no use.
If i unplug the power cord for a short period and inserts it again it works for about 5 minutes then starts the on-off cycle again.
So i guess there is a heating problem with a resistor/capasitor/transistor somewhere? or some voltage building up due to faulty hardware?

My old soldering work was still looking good after a year of playing so i started to look at the traces.. Then i discovered it, a very little bit of a thiny trace had burned(?) of. Looking at the surrounding traces it looks as though there have been some problem with the manufacturing. Several of the traces in the neighbouring area are damaged, looks like the board has been dirty during the production so the traces has been eched a bit to much. (look at picture 1 - closeup. Circle nr.1 shows the trace that was completely broken, Circle nr.2 show a trace that is just half the width it should be)
what i did was to peel of a little bit of the isolation covering the trace nearby the gap and soldered a very thin copper wire across. Due to a flat battery i have no picture of the outcome of this surgery, and who is waiting for the batteries to recharge when the xbox might be working again? not me!
And guess what, when i inserted the power cord it stayed off! And it worked 100% when i used the power button too. So i guess i found the problem, lets just hope the other traces will last a few more years before breaking down..

Xbox is version 1.1 by the way.
