First off, I've been a tech for 12 years. This is the very first time I've been stumped for two months!!! Two freakin months!!

System:
AMD FX-8350
G-Skill DDR3 and Corsair RAM (12 GB, 2x 4gb and 2x 2gb)
1TB hard drive (never given me issues)
Radeon HD 6770
Cooler Master aftermarket cooler

motherboard....well.....

So lets begin in my heartache.

I came home from work and my computer was off. I assumed my kids had pressed a button and turned it off but that wasn't what happened as they have no access to it. I press the power button, and nothing happens. Nothing.

I go out and buy a brand new Corsair power supply to replace my Coolmax.

No boot.

I send my MSI 760GM-E51(FX) motherboard off to be RMA. It comes back and something happens. Fans spin, hard drive spin, CD tray opens and close, GPU fan spins. .....

But no boot, no post, and no beeps.

I send my FX-8350 off for RMA, it comes back. And I got boot! Yay me! I play for a few hours and the world is happy. I go make bacon!

Come back...computer is off. Power it up, and I'm back at fans spinning, tray opening etc, but no POST or beeps.

I replace my motherboard with a GIGABYTE GA-970A-UD3, brand new, and I get fans spinning, CD tray doesn't up but the light is blinking on it but thats it.

But no beeps, no POST.

I'm at my wits end. I've never had this much trouble. I removed aftermarket cooler and went back to stock as well, thinking maybe the backplate was causing a short.

Now before you ask, yes I saw the troubleshooting guide for this issue and went through it (8pin power, RAM replace, etc etc etc) . And yes, my computer WAS WORKING and then went back to the previous issue.

I'm completely out of ideas.

Static electricity or your case shorting out the board, possibly. Check the ground where you have the system plugged in. Is the AC outlet wired correct?

Hi, the CPU requires the F7 BIOS version (with 970A-UD3). Check the motherboard manufacture date to make sure that the BIOS does support the CPU.

1. Manual read
2. 8 pin firmly plugged in
3. All standoffs put in correctly
4. Video card fully seated
5. Video card doesn't require power
6. I have four sticks, I have tried them all, one at a time in both boards
7. Verifyed all RAM
8. Using correct RAM slots
9. Plast guard is not there
10. CPU installed correctly, did it three times to be sure
11. No bent pins, triple checked, + AMD won't do RMA's if there was
12. This may have been the issue with the first CPU, but made sure not happen on the new one
13. CPU fan plugged in and spinning
14. Switched from aftermarket cooler to stock, with stock thermal paste still on brand new
15. No lose screw, made sure of that
16. No static, discharged to be sure
17. System speaker installed, tried flipping it both directions to be sure I had it correctly
18. Front panel plugs are correct
19. Power supply is on
20. CPU is supported with BIOS version
21. Reset CMOS, not that it matters since it doesn't POST
22. Old motherboard had integrated video, tried that. New motherboard doesn't have onboard
23. All components firmly pressed in, including only doing bare minimum to boot

alexoiu :

Version on board says its 3.0, so it should have that BIOS version FA, no way to check to be sure because it won't POST.

spooky2th > I took it to three different plugs in the house, and even took it to work, same results.

giveen :

I can still see a scenario where static charges build up in the case and fry the motherboard (what is the case anyway?)

I know its fairly low chance, but its the only thing left that we can blame

giveen · May 23, 2013

_Brute_Force_ :

Welcome to my two months of hell. Its a brand new board. Just put in, I made sure its on all its standups, so no short, I've discharged by touching the frame.

What do you make of the flashing CD tray light that started with the new motherboard?
Elite 310

Also what do you think about how after replaceing the CPU it worked for a bit?

smorizio · May 23, 2013

I seen this in real life. If you used the old power supply again it could be the old unit is outputting more voltage then the atx spec and it fried both mb and CPU. If you used new power supply then your video card or one of the hard drives has a short In it and it killing your system. I would rma mb and CPU again and start with a bare bone system and check with a volt meter the output on the power supply.

giveen · May 23, 2013

smorizio :

That is basically what I am considering, Hopefully gigabyite is faster with the RMA than MSI was. AMD was great. Also, I need to check on my video card to see if I can return it. I have no spare hard drive nor money to replace it.

giveen :

Reminds me of the time I managed to fry 2 motherboards in less than 30 mins! (massive power fluctuations and bad PSUs don't mix)

but back to the topic, when you clear your head and think about it. "Event x" happens that fries your motherboard and cpu. I'd say its most probably power related, but basic stuff wouldn't hurt the cpu since the motherboard power regulator would handle it.

I'd say in your next trials, only consider the things that were running before everything was fried (like reconsider the cooler).

Got anything that can measure power fluctuation?, you might have been very lucky, twice!

Also try a different GPU if you have one, preferably one that doesn't use external power, could be that 6 pin causing the troubles (but u'd think it would fry the GPU too)

I'm intrigued by this one, can you update back this thread with any progress or post here if you start a new one?

I will post in here what the solution is going to be

GPU actually doesn't take power. XFX Radeon HD 6770.

My guess is one thing (probably something power related) caused everything else.

Right now, brand new mobo is being RMA back to Newegg, waiting for AMD to approve RMA and XFX to approve RMA.

_Brute_Force_ · May 23, 2013

wait a second, I'm pretty sure 6770 uses a 6 pin, isn't this the card?
http://products.xfxforce.com/en-us/Graphics_Cards/AMD_Radeon%E2%84%A2_HD_6770/HD-677X-ZAFV

It says in the specs and I can clearly see it at the top right (facing the right not the top).

giveen · May 23, 2013

_Brute_Force_ :

Sorry, one number off
6670

dammit, thought I figured it for a second lol

giveen · May 29, 2013

So parts are still on their way. XFX hasn't answered my RMA request in 5 days.
So a thought. I'm pretty sure that the motherboard is the root of all this. Do you think that perhaps my motheboard standoffs are too short? Resulting in a short? The reason why I ask is because I bought my new case and my new aftermarket CPU cooler about the same time.

So my thought was that my standoffs are too short, resulting in my CPU cooler (which has a metal brace), touching, and cross-wiring with other stuff that was touching the case as well.

This is my case

I am wondering if I need a taller standoff rather than the typical 5mm.

_Brute_Force_ · May 29, 2013

giveen :

What you can suspect is having an uneven motherboard tray, where its higher and closer to the motherboard at parts where it shouldn't be. Tho I'll be honest, I've never experienced this before, but at this point its more possible than anything else.

Since is a "new" case, does it mean you still have the old one, you might want to rebuild the computer in it just to check that the new one is not the root of all the problems.

New motherboard is ATX, old case (and old motherboard) is microATX but I gave those away already (including my old processor) to my brother-in-law

spooky2th · May 29, 2013

Have you checked the face plate to see if it is touching metal somewhere? On one of your plugs maybe?

giveen · May 29, 2013

The faceplate has the copper tubes touching from the cooler but its touching the plastic seethrugh

giveen · May 30, 2013

AMD says my processor is fine
FD8350FRHKBOX TEST/INSPECTION PASSED

smorizio · May 30, 2013

Has the new mb and video card come in??? If try did try bread boarding the mb outside the case. With one dimm no hard drives to see if they post.
Also check that the rma mb bios is at a rev that will pst with your CPU. Vendor could sent you an older mb.

giveen · May 30, 2013

smorizio :

Motherboard is here, processor will arrive next week. 7 days and no response from XFX.
I'll breadboard it when it all arrives.

Motherboard is revision 3, which should have FX support out of box

giveen · May 31, 2013

Just talked with XFX on twitter, and an hour later, RMA issued and they paid for shipping. Sending it off this afternoon.

giveen · Jun 10, 2013

XFX says inital tests show output on my video card is working just fine, but they are in the first stage of testing.

giveen · Jun 18, 2013

Wasn't able to work on it till late last night. Build was fine on the kitchen table and it POST'd just fine. I put everything in the case, and it booted to linux partition just fine, but keyboard and mouse weren't working. Did some research and found I had to enable an option in the BIOS that has no description on what it does (AMD IOUMMA mode or something like that).

Let it run all night on the linux partition and it didn't shutdown so thats a good sign.

Windows won't boot, keeps BSOD, probably due to motherboard drivers so I'm going to be reinstalling it this morning.
