FS PC just went black! Couple of troubleshooting questions if you will

[Noel 4,487]

Nice!  The recommended PSU tester is excellent!  The written instructions were clear, completely useful and concise.  My 4.3y/o Corsair HX850 is perfect according to the tester.  I'm assuming this does't really evaluate load capabilities though, so this suggests to me it's useful to see if you have a 'dead' PSU, but one in the honeymoon phase of a slow death.  The abrupt stopping of my PC suggests it's not the latter, and the tester proves it's not dead.

I contacted ASUS to RMA for a bench test evaluation.  So I will package it up and send it out and from the sound of it should hear from them within a 1-2d after they receive the motherboard.  They will contact me w/ one of three outcomes:  1. it's fine!  This may me my SB-E is out to lunch.   2.  The X is out and we can replace it and assure it's returned about to at least boot the first time!  It's 4.3y/o board so who knows what all is tired on it.  But if it can get me a few months down the road past Threadcrusher and all issues w/ cooling SkylakeX and X299 boards then I get pick up whatever makes the most sense.  If Intel uses non soldered TIM on SkylakeX it would be one demerit against them just out of principle---costly CPUs.   And 3.  The X is out but it can't be replaced.  At that juncture I will be out of the game for a bit it would seem.

Hey Noel did you ever get this resolved?

Sorry I see I started this post last week but never completed nor hit the Submit Reply button.  

ASUS sent me another refurbished model of my same mobo, I reassembled it all and voila all's well again.  4.42Ghz @1.32v is exactly what I was getting before so I am tickled pink!   It all went back together w/o a hitch, it was newer BIOS than I had installed but the overclock was easy and heat management is as before, excellent.  It's so nice I don't have to reinstall anything and I have no idea how long it will go for but if I can get another year out of it I'd love it.   The cost was $140, and as I say it was not the mobo I sent in but was one of the same model w/ different serial number.

Thanks!
