Well, first off, I messed up the thread title. That should be "Dead in the water". This keyboard is really slow and I type fast.
Windoze is not on my laptop. It runs Ubuntu 14.04 Linux. The original problem started with the screen flashing rapidly. Then it calmed down a little, but started tearing sideways, but on only the upper third of the screen. I thought it might be a chunk of bad video RAM, but running memtest didn't turn up anything. Now when I boot up, it is normal for a few minutes and then goes awry once more.
I didn't bring my computer tools, so I can't check the motherboard, but it is entirely true that a cap may have popped. So, it stays off for now until I get home. I didn't smell burning electrolyte though. A good sign. My 60 years in electronics tells me it wasn't catastrophic.
This computer I am on now keeps hopping out of this edit window and going off into cursor heaven. I have to drag it back and click to reenter this box. Sometimes the cursor hops to a different part of the post. Very unstable.
