Thanks everybody for help,
I will sure try this tool but as i am in business of selling complete rigs customers i sell to are used to simple solutions (few clicks and mining starts).
I am afraid if i start to use this tool which i am sure i will learn how to use, i wont be able to give them support as i do that as a part of my service.Everybody i sell to are used to MSI because mostly those are the people that dont know so much about computers but wants to mine.
About MSI AB i use latest version with latest AMD drivers.
About that windows update i disabled it (first thing i do), i also disabled everything in Task Scheduler which is connected to Windows Update.
What i notices about Trixx is that before he shuts down it seem like something is happening in windows that is causing this shutdowns. Like some programs are opening by themselfs.
Any other soultion guys?
overdrivenNTool is easy to use, it might not have a fancy UI but it gets the job done.
You just have to run it once before the miner starts to set the clock and voltages, like I mentioned in my previous reply.
Trixx and Afterburner run in the background all the time, and that might be the reason of your rig crashing.
Eliminating those programs will increase stability.
Try it out, if the problem persists, let us know

I am guessing thay cause this problems but on Windows 10 old version eveything was fine. The strangest thing is that i have one rig that was updated by force on Windows 10 1709 and still have Windows Update assistant, I literally didnt change anything and it is working fine for 2 months. Problem began when i started to install fresh version of Windows on my rigs. I read somewhere that if I use miningtweaks. bat for removing Windows Apps (Cortana, Xbox,Mail, People...), Windows UI starts messing up (Windows Defender pop up, Control Panel Pop Up) but as i watch and monitor rigs i cant seem to catch that moment. Only when i sleep it happens. What an irony i cant sleep at night
