xbox shuts down after 15 min

[disturber]

Can anyone help me ?
The problem is that my xbox shuts down after playing for some 15 minutes.
I pull the mains , wait some, put the mains back then i won't have to use the powerbutton to power up , it does that by it's self.
It's an old version xbox.

Does your fan still work? Might be overheating if the fan crapped out.

No the fans are working.
I think it's a supply mather.
In some way the powerbutton does'nt work ,or work's all the time.

First I am going to ask if the modchip is enabled/disabled with the power of eject button.

If not, load up evox and let it sit for 15 minutes or whatever. Take a note of the temp.

It probably isn't a temp problem, though. You should check under the power supply. There are 2 points under the cord socket in which the solder cracks off and can cause a lot of problems. My xbox used to do that, I got a new power supply, and now it does it every 2 hours or so. If you have another xbox around, swap HDD's. If the problem stays, then it has to be the mobo.

It's a not modded xbox.
If the solder points are cracked , can it be fixed?

yah, you just have to resolder it. It should fix it, if that is the problem. Before you open the xbox, wiggle the socket up and down from the back. If it moves easily, it is probably creacked. You would also smell that "transformer" electric smell.
