Two things.
A) 8GB could not be enough (recommended 16)
B) if using windows 10 the registry is set to auto update so it has nothing to do with your miner. Windows does automatic updates at a specific time and you need to change the registry file to not update without permission. That happened to me at first when I was using windows and I couldn't figure it out for like 2 days.
Just google "how to stop windows 10 updates" and you will want to use a tutorial that shows you how to edit your registry.
