Hi guys, first off thanks for helping!
heres my issue, since i installed my 2nd 1070 randomly it wont let me launch any game but once i restart my pc its fine, also sometimes when i hover my mouse pointer over my apps on my windows home page they all highlight red and i have to restart my pc to fix it, sometimes it wont do it for weeks and sometimes everyday. ive have the 2nd 1070 with sli for a few months now. my pc specs are below

1) i7 7700k
2) gigabyte gtx 1070 8gb 256 bit Boost: 1771 MHz/ base: 1582 MHz in OC mode, boost: 1746 MHz/ base: 1556 MHz in gaming
3) evga gtx 1070 8gb 256 bit Real Base Clock: 1594 MHz / Real Boost Clock: 1784 MHz; Memory Detail:
4) msi 2 way sli hb bridge m
5) maximus hero ix mobo
6) 2x4 corsair vengeance 2400mhz ram
7) 2x4 xpg (not sure of mhz but ran fine always b4 the 2nd card)
8) psu evga 850 watt bronze
9) windows 10 pro

any suggestions would be great guys and like i said when its not happening my games run great i run fortnite with all settings on epic at 160 fps in busy close range fights

the frequencies show 1037mhz 1066mhz 1066mhz 1200mhz
latency 14 15 15 16

but ive used this same ram for 8 months and no issues, the issue didnt start until i installed the second gpu
