After a few years of collecting dust, I decided to fire up my softmodded xbox.
It boots up through the Xbox boot sequence, then shows the XBMC logo and turns off. I immediately, thought it was overheating, so I opened it up, but can't see any evidence supporting that.
To test my theory, I unplugged the DVD-Drive, started it up. I get the expected Error 12, because it doesn't detect the DVD-Drive, but it stays on perfectly fine, no overheating.
So, I suspect, it's either an issue with the DVD-Drive, or the files on the HDD have somehow become corrupt. And this is why it boots all the way to the XBMC logo then turns off.
Is there any way to test this further? Or anyway to restore/reformat the HDD and start fresh?
