yes it is fully updated. yes I posted a pic here a year or so ago and was told it is the video card. the screen has lines through composed of blocks. when it happens the thing is fully locked then it reboots. it has been doing it for over a year but it is getting more often. I put in the new ssd drive still did it it is plenty fast for what I do so hate to upgrade the ssd drive gave it new life.
no it was horizontal lines like blocks. I broke down and found the 8 gig model on sale. way too easy to change over just took the drive out of my old one put it in the case and off I went. moved photos to the internal drive and iTunes and that freed up most of my ssd space. only problem was my firewire extra drive had to hunt around for a square usb cable. I won't need it down that I have the internal one. the sad part is it really does not give me anything more then I had. wen lI could play more games but I don't really play games on my computer.
Seeing as your not shy about opening it up you should consider reflowing the logic board. More often that not it solves the gpu issue. Then you can run the fans at a higher than default setting to slow the onset of the issue happening in the first place.
