Good afternoon,

If you need a re-run with certain options, let me know.

"dmidecoe" gives me over 1100 lines of output.  Please tell me what options to use to get this down what you need, or some way of paring the output down to a reasonable size.

A few more facts that might provide clues:
* This is a dual boot system; the other OS being windows 7 home.  I experience no problems when using windows.  Does this rule out hardware problems?
* This system has an ASUS Sabertooth Z77 motherboard.
* This system has 16 gigabytes of memory.
* This a dual monitor system.  I have two Dell U-2711 monitors, each 2560x1440.  These are "wide gamut", not sRGB.
* This system has an ASUS Xonar Essence STX audio card.
* This is a "diy" system.

Yesterday evening, the display suddenly wend "psychedelic", showing seemingly random, changing, loudly-colored squares (?) all over both screens.  First time, after a few minutes, I had to shut off the power.  Second time, after several minutes of the "psychedelic" display, it froze, after which I had to shut off the power.  Curiously, the audio CD kept playing normally (with normal sound coming out of the speakers) until I turned off the power.

This is in progress.  I'll post something when I have something worth posting.  A caution about that website.  I loaded the website in Firefox, running in windows.  "NoScript" was active; windows security essentials and Malwarebytes were hooked in.  Yet something briefly flashed on my screen while viewing that site.  It wasn't up long enough for me to see specifically what it was, but it sure looked like an ad.  Subsequent scans showed no problems.  Be careful with that site!

Bill.
