Try swapping in an LCD to see if the problem goes away.

I have two CRT monitors, both work fine with WinXP. Both PC's are identical except one is set up for dual boot. The problem started when I installed Ubuntu and only occurs while running Ubuntu.

Can you confirm you are running both boxes on same ubuntu release (17.04) and the XP does not experience such problems ?
After a blackout, is the pc functional or dead ? Can you perhaps use ssh to connect during blackout ?
You might want to check out the logs during the incident if you can ssh in.

If you cannot ssh, a more serious issue is at hand.
What kind of GPU or GPUs are inside (stock, multiple ..), I suspect radeon ?
Are you using stock out drivers or you installed them and if yes how ?

1. No I have not installed new BIOS. I don't see the need right now, that's not the problem. UPDATE: PC does have latest firmware version.
2. Yes both are running 17.04, and no the problem doesn't occur while logged on to XP.
3. It doesn't black out it just dims and becomes un responsive for several seconds.
4. I will try to locate log files. Didn't know ubuntu recorded such events.
5. integrated intel graphics media accelerator 3100
6. it's using what ever drivers ubuntu loaded when I did the install.

PBUILDER-DIST-SIMPLE(1) 				      General Commands Manual					   PBUILDER-DIST-SIMPLE(1)

NAME

       pbuilder-dist-simple - simple multi-release pbuilder wrapper

SYNOPSIS

       pbuilder-<dist> operation [...]

DESCRIPTION

       pbuilder-dist-simple  is  a  wrapper  that makes it easy to use pbuilder with chroots for many different Ubuntu distributions.  If you need
       more features than pbuilder-dist-simple provides, have a look at pbuilder-dist(1).

USAGE

       Create one symlink to pbuilder-dist-simple for each distribution for which you want a build environment, naming them like "pbuilder-lucid",
       "pbuilder-natty", etc.

       Replace operation with the action you want pbuilder-dist-simple to do (create, update, build, clean, login or execute).

EXAMPLES

       pbuilder-natty create
	      Creates a pbuilder environment for Ubuntu Natty.

       pbuilder-lucid update
	      Updates an existing Ubuntu Lucid environment.

       pbuilder-lucid build ./sample_1.0-0ubuntu1.dsc
	      Builds the specified package on an already existing Ubuntu Lucid environment.

FILES

       By default, pbuilder-dist-simple will store all the files it generates in ~/pbuilder/.  This can be changed by modifying the BASE_DIR value
       on the top of the script to any other directory you want.  If the directory doesn't exit, it will be created at runtime.

SEE ALSO

       pbuilder(1), pbuilderrc(5), pbuilder-dist(1)

AUTHORS

       pbuilder-dist was originally written by Jamin W. Collins <jcollins@asgardsrealm.net> and Jordan Mantha <mantha@ubuntu.com>, and	this  man-
       page by Siegfried-A. Gevatter <rainct@ubuntu.com>.
