All was fine until I started streaming a cnet video over the internet. I think my video card is not happy as the primary laptop screen and the external monitor went both froze and freaked out (I wish I would have taken a photo) but it was clear that they both needed to be turned off right away. I will try and duplicate again.
Disconnect the other hardware, it could be that other monitor.
Which reminds me, do a SMC, PRAM reset, Hardware Test, check the battery etc., might be a power issue.
1. SMC reset

Problems solved: Machine is not booting, power button pressed and nothing happens, problems with indicators, Magsafe has wrong lights, battery is not charging, monitor and graphics issues etc. If the battery is not charged (from like letting it sleep too long), let the Mac charge up awhile first.

Magsafe: Use the correct/matching power supply charger with your Mac, not a less powered one from another Mac.

For those machine that have it, you need to have a Internet connection and hold the D key down for quite some time to load it from Apple's servers.
If it gives anything, write it down and consider taking it in for service.

Is a logic board something I can do myself ?
No unfortunately, it's the whole insides of the main computer.
I have no money for a new machine right now.
Bummers, it's $310+ for a logicboard graphics repair is what I was quoted for that model which that one is likely only worth about $500 to $600 now if the wear isn't bad enough to be seen.
Should I ask a genius for some good will on that one, or give it a try ?
They will hook up their CAT5 cable to it and run a diagnostic, tell you what it is. Gratis.
