Hummm..... I keep thinkin' board short or weak psu. But you've changed both of those. I'm a big fan of the paper washers on top the stand-off screws. I know no-body uses em' anymore, but I like em'. One time I had an amd k6 board that needed paper a washer on both sides of the board on 1 case stand-off screw or it would shut down after the bios posted.
Look's like you guy's have tried nearly everything else so I thought I'd throw that out there. Probably a wild goose chase at best and maybe you've already tried that, but one never knows.. Computers? I am often very surprised about what I think the problem is and what it turns out to be. That's probably why I love em' so much...
Other thoughts: Have you tried firing up the board and booting it out of the case? (Thats really what we're supposed to do when we build a new rig is test everything outta' the case. Myself I just slap it together...But sometimes......) Is it the same make and model case?
It just goes to the boot screen and restarts? Heat? Would make it just shutdown. Unless there's something I don't know going on with the bios and a set restart temp. I doubt it. (Personally I like to blame everything on heat. That's why I try to get the best cooling I can.)
Weak psu? I've got two bad ones inna' row. But never a corsair.. I took me 4years to have a problem with mine. I used to kill an OCZ every year except the powerstream 520 that took 3years. Still..
It's gets to the boot screen where it wants to load drivers wants power. Starts to really charge up the board and devices then the fans quit and it starts over? Everything's been replaced? And it does look like you guy's have tried everything else I could think of.(And then some.)
Sorry if that was no help.
If I think of anything else I'll come back and post.
Best to you and G'luck with that.. "Clay"
