EP2C602-4L/D16 Random Crash / Reboot

Hi, just in case it helps someone:

I built a system with the EP2C602-4L/D16 MB, two Xeon E5 2760 CPUs, two HyperX FURY 8 GB DDR3 1866 MHz, and a Gigabyte NVIDIA GTX 750Ti 2GB PCI-E GPU (just to get an HDMI port).

My first problem was a totally dead system -- it turned out to be the GPU, apparently the board is not compatible with some PCIe GPUs.  (I tried various PCIe settings, like bus protocol version, no joy.)

Anyhow, with a different GPU in, it boots fine; my next problem was random crashes and reboots.  It would run for an hour, or 5 hours, or something, and then either spontaneously reboot, or just lock up.  I couldn't see anything relevant in either the BIOS logs or Windows logs.

It seems this was due to Windows 10 -- apparently it's not compatible with this MB.  I saw in another forum where people with the same issue fixed it by installing Windows 7 to replace 10; I installed Linux, and it works fine now.  (I've been running for a couple of days.)  I have Windows 7 on order.

So it looks like Windows 10 is just no go, but frustratingly it SEEMS to work and then just crashes on you.

Hope this helps!

Thanks for the info. Being an enterprise solution windows 10 support was likely not much of a concern as most people using this type of product tend to favor server OSes over consumer versions. 

BTW this thread seems to cover similar issues, albeit with a different board:
