XBMC4Xbox

I was ftping to it, and had to leave for work, when i came home i tried rebooting it, and it has been fraging ever since.

it was recently modded with xblast lite, and i checked it wasnt the solder for the chip, any other ideas?

What version of xbox?
Will it boot the stock nand ?

1.0, and I have removed the chip, and still fragging

What is the LED pattern?
( as I'm guessing you don't get an error screen, since it's a v1 )

on off on off frag...

What it frag?

If you mean what is frag? It's the LED Flashing Red and Green

I think the PSU is slowly dying. If it's a Foxlink PSU, I would check for cracked joints underneath it. It's the kind of issue you can get as the traces under the PCB heats up and restrict current flow.

This process can be slow enough to take a couple of hours if you're just on the edge of supplying enough current to the CPU. Once the heated joint passed a certain temperature threshold, the current restriction is so great the CPU isn't supplied with enough current and begin to give out all sorts of weird errors, like a FRAG. It's an assumption though.

Easiest way to verify this would be to monitor voltage rails (3.3V, 5V and 12V) coming out of the PSU after the box has been OFF for quite some time (as to make sure the PSU is at room temperature) to get a base reading and check those rails again after 15 hours, when the Xbox starts FRAGging. If voltage drops considerably (>100mV), you have found the problem!
It still doesn't make it 100% the PSU's fault as the issue could be on the motherboard itself (CPU?) but it'd give you a damn good indication why your Xbox FRAGs after such a long period of time.

I own a dead 1.3,could I modify that psu?

Yes, you can rewire it and it will work. I saw some tutorial floating around but those were to use a 1.0 PSU in a 1.2-1.5 Xbox. Reversing the steps should get you going. Be very careful when rewiring the power supply, mixing up voltage rails could end up frying your motherboard beyond repair.
I would do the test I explained in my previous post before doing this though. As I said, maybe it is not the PSU at all and you just have a bad board.

Hi had same problem with my xbox v1.0 i was thinking about a possible bios problem the worst, but the problem was the power supply bad voltage faulty power supply i change the power supply no more frags like new.

bad caps ?
