I have been happily using debian 9 stable on my notebook following "don't break debian" advices but I have some issues recently. It freezes from time to time especially when playing mkv files. This is a hard freeze, no keys work, I have to hard reset my computer. Secondly, screen sometimes (randomly) moves horizontally very fast, but it is hard to describe / explain this problem. It seems to happen randomly. --- Edit: I noticed that this screen "flashing" problem happens when I press a key when there is a video on the screen, in browser or in video player.
This is a notebook with Intel graphics. No external GPU.
Question 1: Could you please help me diagnose & solve such problems?
Question 2: I might consider making a fresh start with installing/resetting debian 9.3 to its original state, keeping my current files & settings in my home. What is the practical way to do that, considering that this is a dual-boot system with Win 10, with separate /home partition and encrypted root, home and swap partitions?

None1975 is right, it sounds like that bug. I was affected by it too, see this thread for possible workarounds:

Re: Screen & system freezing problems / fresh install?
Screen & system freezing is often an hardware problem. It is typically triggered by intensive video use. Check for over heating, etc.
The posts above about a known bug are worth following up.

But using that older kernel will expose you to known security holes, including Meltdown.
