Random Crashes, probably not hardware

I have been struggling with this issue for almost six months now. Without any warning, freezing, or BSoD, the computer shuts down and restarts. I have tried trouble shooting the errors in event viewer but none of them seem to be the source of the crashes. I have had a replacement CPU send from AMD, have had the mobo sent to gigabyte and repaired, tried multiple video cards, rebuilt the whole computer from scratch, and have swapped out the RAM a few times. Basically, I feel fairly confident that this is not a hardware issue. I also purchased a new box because the power button in the old one was faulty. I have tried running the computer with a clean boot (no non-windows applications) per Microsoft recommendation, still get crashes. The frequency is completely random, multiple times an hour or maybe just once over the course of the day. No one program seems to trigger the crashes, I can stress test everything without producing a crash.
I am to the point of wiping the hard drive and re-installing everything unless someone has a brilliant idea that I have not yet thought of.

Build Information:
Windows 7 64 byte
AMD FX-8150 Eight Core Processor 3.6 GHz,
8GB RAM 64-bit
256 GB Solid State HD,
300 GB HD; DVD RW
EVGA NVIDIA GeForce GTX 660 Ti

For your computer restarting, go to start>right click my computer>click the advanced tab, go down to startup and recovery> uncheck the "automatically restart" box. Your computer is probably experiencing system failure. It's probably set to automatically restart when this happens. By unchecking this box, you will receive an error message instead of the restart and that message can help you diagnose the source of this problem.

If you do get a diagnose report then please copy and paste on here and i be glad to look further into why your experiencing this problem as random computer crashes can be more then 1 element of why this is happening.

pcpower silencer 500w. We have swapped it out for two others which produced no change in stability.

I should also mention that I have done a system restore from the windows installation disk with no change in stability.

Thanks Daniel, yes I know I had it set to automatically restart. I think we took it off for a while when the crashes were absurdly frequent but turned it back on after my most recent rebuild. I've turned it off again. I'll let you know if I get anything.

Got a crash but no error message. The whole thing (besides the monitors) suddenly goes dead. It is also not writing dump files despite having that option on. I've tried small dump and kernel with nothing produced.

If i was in your position, i would make a copy of important files and perform a clean install of windows. This should resolve any corruption in your files which could be the source of the problem.

However, having not found the source of the problem, a clean install of windows should resolve this, so i believe that solving this problem ways more to a clean install.

Windows also should keep a record of the error and checks it against microsoft for a solution, this can normally be found in the action centre.

UPDATE

I have performed a clean install of windows. Everything was running well until I had the audacity to install the other programs I regularly use. Now it randomly freezes during use or just dies. I'm working backwards and uninstalling programs until I return to stability. I run Folding@Home which I have long suspected was the source of the problem however the owner of the rig is adamant that we must continue folding.

Seeing as the crashes occur while I'm using it, I don't think this is the issue. I can wake it up from a sleeping state just fine, it what happens 1, 2, 3 hours afterwards that is the problem.

It's a samsung 840
 
Hmmm, no then the SSD is not the problem.
You said you'd tested your RAM...you might retest since the reload, and another thing that might be worthwhile is giving it another 0.05V; same with the CPU. The small voltage bump may increase stability while not sending heat through the roof.
