About a week or so ago my MBP began to freeze up. It seemed to happen when I'd stepped away for a while and the screen saver was running.
A month ago I replaced the internal HD with a 1TB kit from OWC and added one of those cooling fan platforms under the laptop, along with a stand to keep it cool because I'd noticed the laptop running quite hot. It's pretty much stationed at my desk these days. It replaced a stolen MBP from a few years ago.
Anyhow -- the screens (two) get funky pinkish pixels, accompanied by sluggish response or no response then I have to force a shut down. After multiple attempts this afternoon to reboot I got it to run stable enough to get through a little audio editing project before I shut it down.
Early in the edit session, the screens became distorted but to my surprise I was able to save the project and power down and restart.
Does this sound like a Nividia issue or something else? Should I question my install of the new HD?
