New build bootlooping problem

post #1 of 15
Thread Starter 
Yesterday I build a new system for a friend of mine:

# Product Prijs Subtotaal
1 Intel Core i5-6500 Boxed € 199,- € 199,-
1 Gigabyte GA-B150-HD3P € 84,95 € 84,95
1 Fractal Design Define S € 75,95 € 75,95
1 Kingston HyperX Fury HX426C15FBK2/16 € 69,50 € 69,50
1 Corsair CX450M € 52,45 € 52,45
Totaal € 481,85

We reused his HD6950 and hyper 212 evo. He will be upgrading to a 480 or 1060 when those are released.

After building the whole system I started it up and there was noting on the screen. Every 10 sec or so the system just restarts which I interpret as a bootloop.

Things I tried, but didn't solve the problem:
- took everything out of the case and tried to boot with only the bare minimum: mb, cpu, 212 evo, 1 stick of ram, psu, monitor connected to dvi output of the onboard graphics
- swapped the psu with his old one (CM silent pro 500W)
- swapped a stick of memory from my build: Corsair DDR4 Vengeance 3200
- cleared cmos several times between swaps

Things I noticed:
- when it is bootlooping the mb leds light up, the cpu fan/case fan/psu fans run for 10 seconds until reboot (sadly there is no mb error code led thingy)
- the mouse and keyboard leds don't turn on
- the mb does not beep while bootlooping (it only did - even screamed - when I removed the 6950, without removing the 2x 6-pin headers)
- I have not found an burn-marks on the mb or smelled anything suspicious
- It has been bootloping for 30 minutes now and no change

Is it possible that we received a mb/cpu that was doa or am I missing something? Gotta be honest here, this thing is driving me mad! Have build many systems, but have never encountered something like this.

Just a thought but when you tried the stick of ram did you try it in the same slot or you tried different ones? If it doesnt boot from what youve tried (which is absolutely everything) id go towards bad mobo.

You can check the cpu and see if you notice any burn marks or nothing or look for bent pins. Its highly unlikely the cpu is the cause.

I tried different slots and sadly it was still bootlooping.

I agree that a dead mb is much more likely then a dead cpu. Will search for bend/broken pins and burn marks on the cpu and report back.

Yea i would start there, i had the same issue couple weeks ago out of nowhere as my system has been finished for two months. Turns out while filling my system got a bit of water into one of the ram slots, it dried up before i booted of course but ended up leaving a tiny bit of corrosion on the ram stick. Cleaned that up and it booted.

Could be that all the ram slots are dead or theres some bent pins or something but thats what it sounds like, bad mobo.

At the bottom right corner there are 2 pins that look a little bend to me. Do you think it is worth a shot bending them back and see if that helps?

Yes, it is worth bending it back slightly. Take it very carefully and slowly. I'm not sure what the correct tool is used to bend these back. Probably something very thin and doesn't bend too easily. I'd wait for others to comment on this.

Doesnt look bent to me but pic is blurry, if it looks bent to u then try it. Needles work the best.

Although it might have been a long shot, I bend the pins back with a needle like bluej511 suggested (was easy enough; very little force needed). Sadly, still bootlooping. Any other things I could try, or just give up and rma the mobo since it is the most likely cause of the problem?

At this point i would, i mean you could try another cpu ive youve got one laying around but i dont see it being anything else. Youve literally tried everything lol.

Only thing id check is just to make sure everything is plugged in nice and tight. I do know that corsair atx plugs are incredibly hard to plug all the way in. All 3 of mine have done so.

Update: I ended up returning the motherboard to Gigabyte RMA service. The webshop asked me to deal with Gigabyte directly, although I think they are responsible for handling these kind of issue's (in the EU at least). Maybe it was in my best interest anyway, so there wouldn't be a middleman. I received the motherboard and customer support told me there was an issue with the bios and that they fixed it (
NLA-1660011/ Repair Reason Code). Sadly it is still bootloping... To me there are 3 possible reasons:

1. not the mobo, but the cpu was doa
2. the mobo was not (correctly) repaired
3. I am missing something...

Do you guys know if the RMA service would test the mobo to see if it posts? If so, reason 1 seems likely to me and I have to take apart my skylake system to test if the cpu is indeed dead.
