Ok guys I've been struggling for a few days now.
-First I did as guide said. Installed everything smoothly on usb flash drive. 16 gb 3.0 flashdriver. Everything went smoothly until freezes started.
-Then I Changed my USB Drives. Bought a new one and The freezes still happened.
-I switched to usb 2.0 - It still didnt work.
-Then I installed on 120 gb ssd disk, which should perform amazingly better the all the other options. Well not, The rig still freezes.
 * I've changed settings in bios
-Turned off onboard gpu
-Switched from auto to 2Gen
-Disabled fast boot.
 *The problem with usb was, It would do a restart and after a restart it went straight into bios without recognizing my usb flash drive. The ssd on the other hand, just freezes without any reboots or anything.
- Someone suggested I should check the risers but they are all fine. Brand new. The GPU'S are brand new and everything seems to be recognized in the Terminal. The hashes are fine and everything. Any other sultions? Im helpless, my Rigg just goes down sometimes after a 1 hour sometimes after 6 hours.
PS. My internet connection is fine because all the other rigs run on the connection with the same brand SSD's, OS and does just fine.

My setup : H110 Pro BTC+ (Motherboard) / 13 X GTX 1070 Asus Dual / 2x 4GB Kingston Ram / Kingston 120 gb SSD / Some fine ass 1151 socket Intel /Risers are classical 6pin 006c ver / OS : nvOC 19

Will marry you if you help me!
