Still trying to isolate video freezes

Still trying to isolate video freezes

[Chris]

[-- Attachment #1: Type: text/plain, Size: 854 bytes --]

In an effort to try and figure out why the video on my Dell Optiplex 780
keeps freezing I've been advised to run the latest kernel to see if it
may fix the problem. Today I installed 4.6.0-997.201605222202_amd64.deb
and when booting it would not finish at all. There were some statements
about not loading root and also about not finding a drive. Is there a
way that I can save all this information so that I can add it to a bug
report I've filed a long time ago. I'm now back to the kernel below in
my sig. Since I'm not smart on any of this I'm also wondering what the
attached means, if anything at all.

Is yours a SFF model 780? Overheating can cause freezing, and small case 
Dells, like other compact case PCs, are particularly susceptible to 
overheating if allowed to accumulated dust and/or tobacco tar, particularly 
on CPU cooler and/or within PS. Dust collected on tar acts as an insulator, 
containing heat within the source components. If you're sure overheating is 
not your problem, run memtest86 overnight or longer. You might have failing 
RAM. It happens. Sometimes simply reseating RAM will help if testing produces 
errors, but don't count on it.

I can't recall my SFF 780 ever doing as yours with any Linux kernel all the 
way back to 3.11.7 and up through 4.5.4, and servers 1.14.x through 1.18.3.

I believe this issue has finally been resolved. There are two steps I
took. One was to upgrade to the 4.4.0-* kernel. The other was to disable
GkrellM. So far the system has been running perfectly for over a month.
The only time it's been restarted was due to a kernel update. 

Thanks to everyone who helped get this resolved.

Apologies for the repost, I'd forgotten to put RESOLVED in the subject line
