No, it's a 1.6 case. I talked about it in my first post but I've tested the board with the PSU outside of the case and still had power issues. However I've ran into a different issue now. So I wrote on Friday about how the Xbox magically turned back on, but now it's running into an issue where the Xbox will work fine for a couple minutes and then the fan will jump to 100% and shut off. When I try to turn it back on the fan will be at 100%, the light will flash just orange, and it'll shut down, and it'll do that in a loop. So it thinks the Xbox is overheating, even though it's always doing it when the temps are somewhere between 58c-60c. Where should I go from here?

Oh I definitely checked that already, ha, one of the first things I checked. With the Xbox as it is right now, I'm going to go get some electrical tape tomorrow and cover the entire adapter with it just in case it's touching the HDD whenever I put the top case on and see if that does anything.

Right. I've got a breakthrough though. I decided to recheck the voltages on the PSU plug (which they were the same as my first post, nothing changed), and after putting everything back in the bottom case the Xbox turned back on. Everything is inside of the case right now as it should, but the top case is not on and it's powered on fine. Played Amped 2 for a few minutes as well, and it's still on as of this writing. I powered it off about 5 times as well and moved it around a bit and it powered on each time. All of these issues make no sense, haha. It can't be a coincidence though that everytime I put the top case back on it doesn't power back on for a long period of time. Here's a pic of my Xbox as it is right now. All the times before I've squeezed the molex adapter that plugs into the PSU directly beside the IDE/SATA adapter at a 45 degree angle, and then put the extra molex behind the DVD drive. Anyone have a better idea on how to route this before I try to put the top case back on?

Tell me about it, haha. The only thing at this point that I haven't replaced which I haven't ruled out 100% is the IDE/SATA adapter and the top case shorting something when it's on. However even if the issue is caused by one of those, the Xbox should power back on whenever the top case is removed or the adapter is unplugged, which is not the case.

I've been through hell with this Xbox over the past couple of weeks so let me give a bit of a rundown. I've got a 1.6 Xbox that I installed OpenXenium on using an LPC rebuild board, Chimeric's IDE cable, StarTech IDE/SATA adapter, and a WD 2TB drive. For the longest time I had issues with the OpenXenium install where it would FRAG if the chip was installed. I checked continuity and everything was fine with each VIA to its corresponding point, so I redid my soldering twice and it booted into OpenXenium. I then install a dash, setup the new drive, and put the Xbox back together. However it FRAG'ed again whenever I put the top case back with all the bottom screws. Took the case off, still FRAGing. I realized it was FRAGing with just Chimeric's IDE cable after a couple hours so I got a replacement cable, and everything worked fine with the top case back on. Until it didn't. After turning the Xbox off for a few hours it wouldn't turn back on, period. I took the top case off, and it powered on fine, but after a couple seconds I heard a loud whine/squealing noise from the right side of the Xbox (which I assume was the PSU) > turned the Xbox off > and then it never turned back on again, even with just the bare board. So I replaced the PSU. Issue fixed, it powered back on fine. But when I put the top case back on, it wouldn't power back on, and now I'm at the same spot I was before. The Xbox is not powering on no matter what I do. So here's what I've done so far since then to try and narrow this down: I do not know for 100% certain that the motherboard has been case swapped, but I have no reason to believe it was. The bottom stickers were all intact and the screws were not exposed, and there are no missing/extra screw posts on the bottom of the case compared to the board. I've also tested power with the board and PSU isolated from the case and I'm still not getting power, so the case is not the issue I've checked continuity with all VIAs to their corresponding points with a multimeter and they all have continuity. LFRAME is also not grounded I've checked the PSU using this chart here . I'm getting 5.3v on every orange, 0v on white, 0v on red, 0v on yellow, and 0.3v on blue I'm getting 3.25v-3.26v on the collector chip Anyone have any ideas on where to go from here?
