Studio XPS 8100-sudden shutdowns
Have three identical 8100s, and at random intervals they will do a sudden restart. This will happen anywhere from 2-4 times a day. They will do this with nothing else running, including the antivirus and did it new out of the box before I installed any other software. Dell tech support has been no help to this point, their best suggestion was to reinstall from the recovery partition. Having three computers with the same problem would seem to indicate some other issue, if all other 8100s have this problem then there are a lot of upset customers.
Thought it might be an overheating problems but was able to rule that out. Has anyone else had this happen, and if so what was the cure?

I just ran the diagnostics and let it sit for 30min, when I came back it was frozen at the screen that says "No problems have been found with this system so far, do you want to run the remaining memory tests.." but I can't proceed because it's stuck.
I checked the temperature monitoring with lv-sensors in centos and all the cores run around 40C degrees. If I touch the inside heatsink it seems fairly cold actually, but the northbridge chipset heatsink is scalding hot. I read online that this is normal.

It doesn't sound like hardware to me. If you put all of the original hardware back in, will it run through the diagnostics without shutting down?

it's shut down at random with any hardware I put in it. Right now I have swapped everything including the power supply and it still shuts down. And thats with no hard drives, just running off a Centos Live USB. Sometimes it will run for a few hours, some only a few seconds but if I leave it on overnight it is always off in the morning.
Additionally I have disconnected all the USB & front panel devices on the case from the mobo. I'm just going to order a new LGA 1156 micro ATX motherboard online and hope that solves the issue, because I've narrowed it down to the mobo / cpu and I seriously doubt it's the CPU.

So I replaced the motherboard, and less than 48 hrs later it started doing the same again. There's only one possibility left and thats the CPU, so I put the i7-860 in another Dell XPS 8100 and sure enough it started rebooting too. This is the first time I've experienced this kind of issue with a cpu. I always assumed a cpu was either working or completely dead.

I have been struggling with this machine for years:
I tried reinstalling Windows, uninstalling and reinstalling drivers, changing all the power settings, etc
I have replaced the power supply with this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817151095
I have replaced the RAM with these http://www.amazon.com/gp/product/B00683X4PQ
I replaced the motherboard with the same model as the original http://www.amazon.com/gp/product/B0062QDRGU
Now the fans are quiet, I have no BSOD's, and it has been rebooting less, but it still stops responding to USB input after being left idle every single day.
I am at wit's end. After reading neilt51's story I have ordered a replacement power switch http://www.amazon.com/gp/product/B007RZLAO6 and praying that it will be the solution.
