I finished installing all the hardware in my new computer this afternoon and have run into problems. The new parts is as follows.

Corsair HX 850i psu
Asrock x370 Taichi
Rysen x1800
Corsair DDR4-3200 16 gb
Asus Strix 1070 gtx
Corsair h100 v2 water cooling
Samsung SSD 850 Evo 500 gb
Corsair 450R Obsidian case

My problems are these. The computer will start, but I get no signal from the 1070 to my monitor. The computer will stop after a few moments and then restart. Post code is showing either 46 or 4b. Things I have tried are starting with only one stock of ram and I have tried clearing the cmos a number of times.
