I've got a mid 2010 MBP with 8gb, 500gb 850 Evo SSD, Nvidia 320m GPU. Never had a single issue with the machine. I've used Windows in bootcamp to play games since the day I bought it. Now, the other day I hooked it up to a really large TV for the first time ever and had it running for awhile. I realized that it was extremely hot in the upper left corner when I touched it, hotter than I've ever felt it before (but it didn't shut down or anything). This was in Windows. So I shut it off and unplugged it from the TV. Now ever since that happened when I play games I get screen tearing pretty bad, which has never once happened before. It seems to be fine in OSX, although I don't have any games in OSX so maybe I should try that. I fear that I may have ruined my GPU having it output that the big screen? Thoughts? Thank you.
