Can't tell where the instability is

Hello,

I am at a point where I need to see if anyone has any thoughts on what is happening with my system.

Almost 2 weeks ago I was playing some Battlefield 4 when suddenly my graphics driver failed as I was about to close BF4 with task manager my computer rebooted. I got back into the OS I tried BF4 and they system crashed again.Needless to say I originally though this was a software issue did a bunch of troubleshooting with no luck so I made a backup of my RAID over night and shut the computer down so I could look at it when I got home. After all this I had some issues where i could not POST. I managed to fix that with clearing the CMOS and flashign a new BIOS.

Now I am still at the point where I can't load games but the system also crashes when using IE. I have rules out an OS issue as when I run Memtest86+ 5.01 from flash drive with all 4 stick the system reboots somewhere in the 30-50% range of the first pass. I dropped down to 2 sticks made past the first pass but the system rebooted at the 30-40% mark on the second pass. I switched to the other sticks same issue and rebooted about the same spot. I dropped to 1 stick and I made it past the 1st pass and when it made it to 70% of the second I killed the test and tried loading Unigine Heaven and the system crashed again.

At this point I am 80% certain it is the MoBo, but I am wondering if it is the ram that is the issue. I am also wondering if maybe there is something up with the PSU since the system just turns off and starts up again and it only happens under load. I have another of the same PSU to test with which is tonight's project. I have more ram coming next week to test that as well.

Any thought's on what is going on would be greatly appreciated.

As for the Specs:
Intel i7 - 5960x not over clocked right now.
R5E MoBo
Intel SSD 750 PCIe 1.2tb
4x 2tb Seagate SSHD in RAID 0
1 kit of CMD32GX4M4A2400C14
EVGA 980ti Hydrocopper
Corsair AX1200i PSU

The MoBo, GPU and CPU are all water cooled.

The SSD is in a 16x slot

The Sata Controller 1 is currentyl in RAID not AHCI. I am not sure if there is a setting for the SSD but I can look when I get home.

The CPU is supported and has been since the first BIOS. I am Currently running v3202 which is the latest and greatest

I switched controller 1 into ahci mode but my ssd which is my windows install drive is a pcie nvme. I did not get the other psu installed lastnight. I thought I would wait and change the pumps at the same time.

But you did give me a thought. I am going to install another drive install Windows and see if it is the ssd.

So new findings from the weekend that make this even more confusing.

I hooked up a gtx 480 and guess what I can actually run Unigine Heaven and Valley. So I hooked the 980ti into a server I had laying around, wouldn't let me into the OS. Hooked it into another computer and it crashed the system just like it does to my good rig.

I also decided to test the ram with Memtest86 + 6.3 one stick at a time. The first stick I tested worked fine made it though the tests, switched to another and it crashed. The odd thing here was the first stick that passed was the one that crashed on Memtest86 + 5.01. So I put the first stick I tested back in and it crashed. Today I should have a new kit of ram to test with. If they fail I will be swapping the board out with my spare and retest all the hardware to see if it is the MoBo messing things up

Well finally came up with the cause. Part one my GPU is messed up, I had a friend try to use it in his rig and he couldn't even install drivers. The second part is the MoBo. I installed the test board and put all the ram in and tested and it works perfect, no crashing in memtest. So it is RMA time for both the board and GPU

ive ran into weir ram voltage drop off issues that were crashing video card driver belive it or not try upping your ram voltage for mine it runs at default 1.6 volt had to up it to 1.65 now graphics drivers run perfectly fine with only game crashes on older games I fix with large access aware .

sorry don't type so well bad hand from years of welding swear 90 percent of the time windows 10 or android auto correction makes things worse

That is odd. I am not sure this is the case. The GPU ran perfectly fine till suddenly it didn't and I would expect that would be system specific, but this card is acting up on 5 different MoBo's. 2 with the same CPU and ddr4 Ram, 2 with ddr2 and 1 with ddr3.

It definitely isn't a psu issue. I have two of the same and still have the same issue and the other computer draws significantly more voltage. Also one of the test rigs that I used had a 980ti in it and I swapped this one in and it crashed, but work fine with the other card. This is definitely an RMA situation.
