I have a Dell XPS 9550 and was dual-booting Windows 10 with Ubuntu 16.04. Over the weekend, I upgraded to 16.10 and then 17.04 without any apparent problems.
Since the upgrade, however, here is what happens:
Icons on the launcher disappear and indicator icons turn into blank squares
If I have a terminal open, commands are no longer found. E.g., I enter `dmesg` and it comes back with "command not found". `/bin/dmesg` gives same result
I have to do a power reset; when I press the power button, the screen will go black with a blinking cursor in the top left corner.
Occasionally when this has happened I see this error message: http://imgur.com/a/vysAx
I tried booting from a live USB and running fsck, and it came back clean.
I tried doing a clean install, during which I:
deleted the swap partition
deleted the ext4 partition with the Ubuntu installation
created a brand new ext4 partition and installed 17.04
Here's my current partition setup:

Read NVMe SMART/Health Information failed: NVMe Status 0x2002
I'm not experiencing any I/O errors when in Windows.
I have not yet determined any pattern or apparent cause for the I/O errors (i.e., it doesn't appear to be correlated with a specific app or happen after a certain interval).
So, what other diagnostic steps would you recommend I take? Any ideas for solutions, or is my best option to do a clean install of 16.04 (where, again, I had zero problems) and just keep using it for the time being?
Thanks in advance for your advice.
