issues with asrock 990fx killer

Before tearing it down .......

1. Check that you are using the latest non-problematic driver for your video cards.

2. Baring that, pull the two R9 280X's and test with a different single video card.


EDITED to include "different"

Well I'm pretty much out of ideas. If it started with Windows 10, it would be easy to assume that it's a Windows issue, but why would going back to Windows 8 not help? Does Windows make changes in the NVRAM or anywhere else which might cause the observed behaviour and would not get changed back by Windows 8? It just sounds so weird that it makes me think it's just a coincidence that the symptoms started after installing Windows 10. But I'm no expert and I also have personal experience of Windows doing weird stuff on my ASRock motherboard*, so I'm not willing to rule out any possibility. Unfortunately, I can't really help with this either. At least the problem doesn't seem to be the CPU, which I guess is good news.

*I had to edit Windows boot options manually using bcdedit to be able to boot to grub, since booting to Windows erased the Ubuntu boot option from the BIOS/UEFI boot menu, even though the EFI partition had all the required files intact.

wanted to update that i switched out my fx 8350 for jmy wifes fx4300 now this will tell me if the board or cpu is bad im also testing my fx 8350 in my wifes pc she has a different board but same brand name

Luckily there's a way to check this: you could try running Linux. You can either use a Live CD if you have one already, or make a bootable USB stick using some Linux image. I'm not sure it matters which Linux distro you use for this, but Ubuntu 14.04.3 LTS should be a pretty safe bet (see http://www.ubuntu.com/download/desktop/try-ubuntu-before-you-install). You don't need to install Ubuntu, you can just run it off the USB stick. If the computer is stable under Ubuntu, then I'd say the issue is somehow linked to Windows.

Thats the thing it all started with windows 10 and i gone to windows 8.1 tp see if the problem would jump from os to os and it did tho it doesnt afect window 8.1 as it did windows 10 but it still freezes up tho

I did do memtest86 on all chips before i came looking for help and no errors were found the test run all night on all chips sepertly
