If you're getting a WHEA_UNCORRECTABLE_ERROR when you BlueScreen, it usually means something is not getting enough Voltage. I don't know if you could see the error or not, but that could be a reason. If you're BSODing during gameplay, it could be a CPU overheat, Overclock Instability, Or just a display driver error. I had those a lot when I got my 980 Ti and after I updated the BIOS(Dated after Windows 10 release), the GPU BSOD stopped and hasn't come back yet.
