Q: flashing pixels

I sometimes suffer from Flashing pixels on my mac mini. Mac mini also shutsdown after that and get a message on start up that something has gone wrong.

check you monitor cable,
remove it and put it back on, possibly switch the ends.
Do you have an adapter connected to the cable itself?

pull the mini out too, inspect the pins on all ends. If you have compressed air spray over the top, not directly into the pin array or you could damage them.

something is lost in translation here.
you still see if when the computer is shut down? If so it's the cable or the monitor.
Is the monitor plugged directly into the wall or power strip or battery backup?

It's a Kernel Panic. The report is stored and can be read using the Console app (found in /Applications/Utilities/) under System Diagnostic Reports.
From everything you have said I suspect it's a graphics hardware issue. Run Apple Hardware Test.
